You have 1.2 x 10^25 particles of NiCO3. How many grams are present?

Answers

Answer:

2365.0 g

Explanation:

First we convert 1.2 x 10²⁵ particles into moles, using Avogadro's number:

1.2 x 10²⁵ particles ÷ 6.023x10²³ particles/mol = 19.9 mol

Then we convert 19.9 moles of NiCO₃ into grams, using the molar mass of NiCO₃:

NiCO₃ Molar Mass = 118.702 g/mol19.9 mol * 118.702 g/mol = 2365.0 g

Answer the following questions about the solubility of CoCO3(s). The value of Ksp for CoCO3(s) is 1.0 × 10^−10.
A. Calculate the value of [Co2+] in a saturated solution of CoCO3 in distilled water.


B. If 0.10 M of Co2+ is already present in distilled water, calculate the molar solubility of CoCO3(s).


C. Explain why CoCO3 is less soluble in distilled water that already contains Co2+

Answers

Answer:

Attached picture.

Explanation:

(1) Ksp equals the product of [Co 2+][CO3 2-]. CoCO3 is excluded from the equilibrium expression because it is a pure solid. The mole ratio of Co 2+ and CO3 2- is 1:1 so their molar solubilities are the same.

(2) There is an initial concentration of 0.10 M Co 2+ so write that in the "I" row for Co 2+ on the ICE table. When you find the zeros of the quadratic when solving for "s", take the positive value rather than the negative value because concentration cannot be negative.

(3) Extra products will cause the equilibrium to consume products and form reactants. So the reverse reaction will occur faster than the forward reaction. More products mean an increased Q value compared to K, since the numerator of [tex]K = \frac{[products]}{[reactants]}[/tex] increases.

What would happen to the position of the equilibrium when the following changes are made to the reaction below?
2HgO(s) ↔ Hg(l) + O2(g)

1.) The pressure on the system decreases.

Answers

Any impact on pressure will only affect gas molecules. So in this question the reactant has 0 gas molecules and the products have 1 gas molecule (the O2 molecule).

This means when you decrease the pressure the equilibrium will shift in order to oppose this change.

As you decreased the pressure it will move to the reaction that will increase the pressure back to equilibrium. So if you decrease pressure the equilibrium will shift to the right hand side (forward reaction) to oppose the change in pressure and a higher yield of Hg(l) and O2(g) will be produced.

Data:
2Fe(s) + O2(g) => 2FeO(s) ΔH = -545.6 kJ
4Fe(s) + 3O2(g) => 2Fe2O3(s) ΔH = -1,643.6 kJ
3Fe(s) + 2O2(g) => Fe3O4(s) ΔH = -1,117.7 kJ

Given the data above, determine the heat of reaction, ΔH, for the reaction:
2 Fe3O4(s) => 2 Fe2O3(s) + 2 FeO(s)

Answers

Answer:

ΔH = 46.2 kJ

Explanation:

Hello there!

In this case, according to the given set of reactions and the required one, it is possible to apply the Hess' rule in order to realize the following manipulations to obtain the required reaction:

1. Keep this reaction as it is.

2Fe(s) + O2(g) => 2FeO(s) ΔH = -545.6 kJ

2. Keep this reaction as it is.

4Fe(s) + 3O2(g) => 2Fe2O3(s) ΔH = -1,643.6 kJ

3. Reverse double this reaction so that we obtain:

2Fe3O4(s) => 6Fe(s) + 4O2(g) ΔH = -(-1,117.7 kJ)*2=2235.4kJ

Add them up to obtain:

2Fe(s) + O2(g) + 4Fe(s) + 3O2(g) + 2Fe3O4(s) => 6Fe(s) + 4O2(g) +2Fe2O3(s) + 2FeO(s)

Simplify common terms to obtain:

2 Fe3O4(s) => 2 Fe2O3(s) + 2 FeO(s)

Therefore, the enthalpy of such reaction is:

ΔH = 2235.4kJ -545.6 kJ -1,643.6 kJ

ΔH = 46.2 kJ

If 74.5 m of oxygen are collected at a pressure of 98.0 kPa, what volume will the gas occupy if the
pressure is changed to 90.4 kPa?

Answers

Answer:

80.8 mL

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 74.5 mL

Initial pressure (P₁) = 98.0 kPa

Final pressure (P₂) = 90.4 kPa

Final volume (V₂) =?

The final volume of the gas can be by using the Boyle's laws equation as follow:

P₁V₁ = P₂V₂

98 × 74.5 = 90.4 × V₂

7301 = 90.4 × V₂

Divide both side by 90.4

V₂ = 7301 / 90.4

V₂ = 80.8 mL

Thus, the volume of the gas is 80.8 mL

You are attempting the reduction of quinone with sodium borohydride. After adding the 0.05 g of NaBH4 you note that the solution remains yellow. Following the procedure, you continue to add increments of 0.05 g NaBH4. You note that the yellow color remains even after the addition of 0.10 g of extra NaBH4. Several students around you are experiencing a similar problem. Propose a cause for this and suggest a solution.

Answers

Answer:

When benzoquinone reacts with sodium borohydride, which is yellow in color, white and colorless hydroquinone is formed.

Explanation:

The reaction described below should occur. However, even as we add more sodium borohydride, the color stays yellow. This implies that the solution must contain unreacted benzoquinone. Furthermore, NaBH4 is a kind of hydride (H-), and the reaction starts with the addition of hydride.

The acid oxygen is protonated once more to produce a neutral primary alcohol. As sodium borohydride is a reducing agent, adding more will not cause the benzoquinone to react with it, increasing the amount of NaBH4 will not affect the color of the benzoquinone.

Often, benzoquinone is very vulnerable to solid minerals, acids, and alkalis, causing it to condense and decompose.

A 250mL beaker is submerged in a large container of Liquid A and turned upside down, and another 250mL beaker is submerged and turned upside down in a large container of Liquid B. Hydrogen H2 gas is bubbled into each upside-down beaker until 100mL of liquid has been displaced. The masses mA and mB of hydrogen inside each beaker is then chemically determined. Note for advanced students: you may assume the solubility of H2 in either liquid is very low.

a. mx will be greater than my
b. mx will be less than my
c. mx will be equal to my
d. It's impossible to predict whether mx or my will be greater without more information.

Answers

Answer:

Mx will be less than My.

Explanation:

The correct option is - Mx will be less than My.

Because, liquid X have been higher viscosity and vapor pressure than liquid B.

Vapor pressure of liquid A is greater, so the amount of liquid X will vaporized greater and H2 gas has been displaced greater from the beaker as compared to liquid Y.

The amount of H2 in liquid Y remains greater in beaker as compared to liquid X.

So, Mx will be less than My.

Calculate the mass (grams) of 0.750 moles of Al2(Cr2O7)3

Answers

Answer:

526g is the mass of this sample

Explanation:

To solve this question we must, as first, find the molar mass of Al₂(Cr₂O₇)₃ using the periodic table. The molar mass is defined as the mass of this compound per mole. With this value we can find the mass in 0.750 moles as follows:

Molar mass Al₂(Cr₂O₇)₃

2Al = 2*26.98g/mol = 53.96g/mol

6 Cr = 6*51.9961g/mol = 311.9766g/mol

21 O = 21*15.999g/mol = 335.979g/mol

53.96g/mol + 311.9766g/mol + 335.979g/mol

= 701.9156g/mol

The mass of 0.750 moles is:

0.750 moles * (701.9156g / mol) =

526g is the mass of this sample

N₂ + 3H₂ --> 2NH₃

If 207.0 g of H₂ reacts, what mass of NH₃ is produced?

Answers

Answer:

69mol

Explanation:

The balanced chemical equation given in this question is as follows;

N₂ + 3H₂ → 2NH₃

The above balanced equation shows that 3 moles of hydrogen gas (H2) reacts to produce 2 moles of ammonia (NH3).

To convert the given mass of hydrogen to moles, we use the following formula:

mole = mass/molar mass

Molar mass of H2 = 2g/mol

mole = 207/2

= 103.5mol

If 3 moles of H2 produce 2 moles of NH3,

Then, 103.5mol of H2 will produce 103.5 × 2 / 3

= 207/3

= 69mol

The water treatment plant adds chlorine gas to the municipal water supply to
control microorganisms. If a technician adds Cl2 at a rate of 1 mg per liter of water,
what is the molar concentration of chlorine in the drinking water?

Answers

Answer:

1 × 10⁻⁵ M

Explanation:

Step 1: Given data

Concentration of chlorine: 1 mg/L

Step 2: Convert the concentration of chlorine from mg/L to g/L

We will use the conversion factor 1 g = 10³ mg.

1 mg/L × 1 g/10³ mg = 1 × 10⁻³ g/L

Step 3: Convert the concentration of chlorine from g/L to mol/L (molar)

We will use the molar mass of chlorine: 70.91 g/mol.

1 × 10⁻³ g/L × 1 mol/70.91 g = 1 × 10⁻⁵ mol/L = 1 × 10⁻⁵ M

Task:Your task is to design a simple interactive inventory management system using Python functions.Question:You are asked to build a simple inventory management system for storing and updating information about a company's products. To simplify, assume that this company has only three products. For each product, the system stores a record about its inventory level (number of items) and the price of each item. Note that this information will need to be initialized before running the program.There are three main operations provided by the system (listed below). When the system is started, the program should list these three operations and let the users choose which one to execute. These functionalities are as follows:1) Generate overall statistics for the entire inventory (total number of items, average price per item, the minimum number of items among the products and the maximum number of items among the products).2) Retrieve information (quantity or price) for a given product3) Update information (quantity or price) for a given productOnce the user makes a selection, the program should invoke a relevant function and complete the operation. The system should continue running (i.e., functionality selection should be provided to the user repeatedly) until the user kills the execution of the program (possibly with a unique input character). One possible system design could have four functions:Function 1: display_system_operationsInputs: NoneOutputs: NoneDescription: This function prints out all possible operations of the system for the user to choose.Function 2: generate_overall_statsInputs: NoneOutputs: Print overall statisticsDescription: This function generates all basic statistics of all products, such as the total number of items, average price per item, the minimum number of items among the products and the maximum number of items among the products.Function 3: retrieve_informationInputs: product name and information type (quantity or price or both)Outputs: Print the information requestedDescription: This function retrieves the relevant information for a given product, which is obtained from the user as an input.Function 4: update_informationInputs: product name, information type (quantity or price) and the updated quantity or priceOutputs: NoneDescription: This function updates the quantity or price information in the inventory.Hints:1) You can initialize the product quantities and the prices using lists. For indexing the products, you can use a list of lists.2) Remember that lists can be modified directly; the important thing is to identify the correct indices based on user input.3) You can use formatting options (the format method) to print out nicer looking outputs.4) You can design a main function which will be the starting point when you execute the entire program. Main function is also a function like others.Using python What was the purpose of the US tariffs?
