Answer:

4.02g of Na2CO3⸱2H2O must be added completing the volume of the solution to 100mL

Explanation:

A 3%(w/v) solution contains 3g of solute (In this case, Na2CO3) in 100mL of solution.

Assuming we require 100mL of solution we must add 3g of Na2CO3. The reactant that is available is its dihydrate, with molar mass:

106g/mol + 2*MW H2O

106g/mol + 2*18g/mol = 142g/mol

That means the mass of Na2CO3.2H2O that must be added to prepare the solution is:

3g Na2CO3 * (142g/mol Na2CO3.2H2O / 106g/mol Na2CO3) =

Answer:

An ion found in some compounds used as antiperspirants contains 13 protons and 10 electrons. What is its symbol?

Solution

Because the number of protons remains unchanged when an atom forms an ion, the atomic number of the element must be 13. Knowing this lets us use the periodic table to identify the element as Al (aluminum). The Al atom has lost three electrons and thus has three more positive charges (13) than it has electrons (10). This is the aluminum cation, Al3+.

Answer:

The mass of iron needed to react with the oxygen is 70 g.

Explanation:

The balanced chemical reaction between iron and oxygen is given as;

4Fe    +  3O₂    ---------->    2Fe₂O₃

Molecular mass of 3O₂:  3(16 x 2) = 96 g

Molecular mass of 4Fe: 4(56) = 224 g

96 g   of  O₂  ---requires--------> 224 g of Fe

30 g of O₂ -------requires--------->?  Fe

=   (30 x 224) / 96

= 70 g

Therefore, the mass of iron needed to react with the oxygen is 70 g.

Chemical fertilizers contain various chemicals that cause harm to soil and water.

Explanation:

Chemical fertilizers contain various chemicals such as phosphates, nitrates which can cause water pollution. Eutrophication caused by the environmental nitrogen and phosphorous that causes rich minerals and chemicals in the water.

These can cause excessive growth of the algae and phytoplankton that will cause depletion of the oxygen from the water body and organisms will die due to this.

B. Eastern Europe

Explanation:

The economy of Eastern Europe depends on producing foods. For example, Poland and Belarus are two countries in Eastern Europe, and they both produce chocolates. Producing foods isn't the only detrimental part of the region's economic data. The other half depends on consumer goods. For example, Estonia and Latvia are good countries in packaging food. The answer to the question is B.

Answer:

44.62 kJ

Explanation:

Firstly, we calculate the energy needed to heat the liquid (ethyl alcohol) by using the formula:

Q = m × c × ∆T

Where;

Q = Amount of heat (J)

m = mass (g)

c = specific heat of ethyl alcohol = 2.138 J/g°C

∆T = change in temperature (°C)

According to the information given in this question;

Q = ?, m = 50.0g, ∆T = (78.4°C - 60°C) = 18.4°C

Therefore, using Q = mc∆T

Q = 50 × 2.138 × 18.4

Q (amount of energy needed to heat ethyl alcohol) = 1966.96 J

Next, we calculate and add the amount of heat needed to vaporize by using the formula;

How many kilojoules of energy are required to heat 50.0 g of ethyl alcohol from 60.0 °C to 78.4 °C and vaporize it? The specific heat of ethyl alcohol is heat of vaporization is 853 J/g.

Answer:

1644 g

Explanation:

Step 1: Write the balanced equation

N₂ + 3 H₂ ⇒ 2 NH₃

Step 2: Calculate the moles corresponding to 2000 g of NH₃

The molar mass of NH₃ is 17.03 g/mol.

2000 g × 1 mol/17.03 g = 117.4 mol

Step 3: Calculate the moles of N₂ needed to produce 117.4 moles of NH₃

The molar ratio of N₂ to NH₃ is 1:2. The moles of N₂ needed are 1/2 × 117.4 mol = 58.70 mol

Step 4: Calculate the mass corresponding to 58.70 moles of N₂

The molar mass of N₂ is 28.01 g/mol.

58.70 mol × 28.01 g/mol = 1644 g

Explanation:

Answer:

Molarity of NaOH = 1.8 M.

Explanation:

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

Mass of NaOH = 36 g

Molar mass of NaOH = 40 g/mol

Volume = 500 mL

Molarity of NaOH =?

Next, we shall determine the number of mole in 36 g of NaOH. This can be obtained as follow:

Mass of NaOH = 36 g

Molar mass of NaOH = 40 g/mol

Mole of NaOH =?

Mole = mass / molar mass

Mole of NaOH = 36 / 40

Mole of NaOH = 0.9 mole

Next, we shall convert 500 mL to L. This can be obtained as follow:

1000 mL = 1 L

Therefore,

500 mL = 500 mL × 1 L / 1000 mL

500 mL = 0.5 L

Finally, we shall determine the molarity of NaOH. This can be obtained as follow:

Mole of NaOH = 0.9 mole

Volume = 0.5 L

Molarity of NaOH =?

Molarity = mole / Volume

Molarity of NaOH = 0.9 / 0.5

Molarity of NaOH = 1.8 M

Answer:

3441.6 grams.

Explanation:

2 O₃ → 3 O₂

First we convert 71.7 moles of ozone (O₃) into moles of oxygen gas (O₂), using the stoichiometric coefficients of the reation:

71.7 mol O₃ * [tex]\frac{3molO_2}{2molO_3}[/tex] = 107.55 mol O₂

Then we convert 107.55 moles of O₂ into grams, using the molar mass of O₂:

107.55 mol * 32 g/mol = 3441.6 g

The amount of thermal energy stored in an object depends on three things.

The correct option is :

=》It has a high magnitude.

the damage caused by an earthquake is proportional to its magnitude, as much the magnitude is, that much damage will be caused by it.

The term used to indicate and earthquake that causes major damage to buildings in an area is called a high magnitude earthquake. Hence, option a is correct.

The most typical way to gauge an earthquake's size is by its magnitude. No matter where you are or how violent the shaking is, it is the same number since it represents the size of the earthquake's source.

The USGS no longer uses the outmoded Richter scale to determine the magnitude of major, teleseismic earthquakes. Several magnitude scales measure various aspects of the earthquake, but the Richter scale measures the biggest wobble (amplitude) on the recording.

Currently, the USGS uses the Moment Magnitude scale to report earthquake magnitudes, however many different magnitudes can be calculated for comparison and research. Therefore, option a is correct.
