Identify the correct equilibrium constant expression
for this equation:
C6H1206(s) + 60,(g) <—>6C02(g)+ 6H2O(g)

Answers

Answer: Keq= [CO2]^6[H2O]^6/ [O2]^6

Explanation:

The correct equilibrium constant expression for this equation C6H1206(s) + 60,(g) <—>6C02(g)+ 6H2O(g) will be

keq = 6[co2] 6[h2o] / [c6h1206] 6[o].

What is the equilibrium constant?

All reactions tend towards the state of chemical equilibrium. It is the point at which both the forward process and the reverse process are taking place at the same rate.

Since the forward and reverse rates are equal, hence the concentrations of the reactants and products will be constant at the equilibrium state. Here, it is important to remember that even though the concentrations are constant at equilibrium.

The double half-arrow sign we use for writing the reversible reaction equations. It is represented as a sign of equilibrium.

therefore, the correct equilibrium constant expression will be C6H1206(s) + 60,(g) <—>6C02(g)+ 6H2O(g)

1) The Specific Heat Capacity at 25°C of Gold is 0.129 / (g°C)

a) What is the molar Specific Heat Capacity of Gold in J/(mol °C)​

Answers

Answer:

25.4 J/mol

Explanation:

The specific heat of any substance is referring to the amount of energy required to raise 1 gram of that substance 1 degree kelvin. Molar heat capacity is referring to the amount of energy required to raise 1 mole of that substance 1 degree kelvin. So in order to solve for molar heat capacity of gold we must convert from grams of gold to moles of gold.

( 0.129 J /g) ( 196.97 g/ m o l ) = 25.4 J m o l

196.97 is the molar mass of gold which can be found on the Periodic Table of Elements. Because grams are located on both sides of the denominator they cancel out leaving us with our new units of J/mol.

A chemist titrates 0.200 M NaOH, strong base, with 50.00 ML of 0.150 M HCI, strong acid. How many mL of NaOH will be required to titrate to the endpoint

Answers

[tex](normality \: of \: acid)×(volum \: of \: acid) = (normality \: of \: base)×(volum \: of \: base)[/tex]

0.15N × 50mL = 0.2N × (Vbase)

75mL = Volum of base

37.5mL of NaOH will be required to titrate 0.200 M NaOH, strong base, with 50.00 ML of 0.150 M HCI, strong acid to the endpoint.

How to calculate volume?

The volume of a solution can be calculated using the following formula:

C1V1 = C2V2

Where;

C1 = initial concentrationC2 = final concentrationV1 = initial volumeV2 = final volume

C1 = 0.200MC2 = 0.150MV1 = ?V2 = 50mL

0.2 × V1 = 0.150 × 50

0.2V1 = 7.5

V1 = 7.5/0.2

V1 = 37.5mL

Therefore, 37.5mL of NaOH will be required to titrate 0.200 M NaOH, strong base, with 50.00 mL of 0.150 M HCI, strong acid to the endpoint.

Answers

Answer:

Ka=[H+][A−]/[HA]

which solution has the lower pH, 0.10MHF(aq) or 0.10MHC2H3O2(aq) :

Higher value of Ka indicates greater ionization thus more protons in solution, higher H+ concentration in solution means lower pH value.

Since HF have higher Ka have, thus HF solution will have lower pH.

The measurement is when the solution has the lower pH so HF should have higher ka.

Measurement when the solution has the lower pH?

In the given solution, it contains the  lower pH, 0.10MHF(aq) or 0.10MHC2H3O2(aq).

Here higher value of Ka represents the high ionization so there should be more protons in the solutions. and, the higher h+ concentration have the lower pH value.

So in the case when HF has higher Ka, due to this, HF solution will have lower pH.

Answers

Answer:

Explanation:

Step 1: Given data

Initial volume (V₁): 0.125 LInitial concentration (C₁): 3.00 MFinal volume (V₂): 0.325 LFinal concentration (C₂): ?

Step 2: Calculate the final concentration of the solution

We want to prepare a dilute solution from a concentrated one by adding water. We can calculate the concentration of the dilute solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁/V₂

C₂ = 3.00 M × 0.125 L/0.325 L = 1.15 M

what is the mass of 1.5 x 10^21 silicon atoms?







Answers

Answer:

0. 070g

Mass of 1 Si atom =28.08/6.022*1023

So mass 1.5 *1021*4.6629*10-23

Answer:

[tex]\boxed {\boxed {\sf 0.070 \ g \ Si}}[/tex]

Explanation:

We are given a value of atoms and asked to find the mass. We can complete this in 2 steps.

1. Convert Atoms to Moles

First, we have to convert atoms to moles. We use Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance.

In this case, the particles are silicon atoms. We can set up a proportion.

[tex]\frac { 6.022 \times 10^{23} \ atom \ Si }{1 \ mol \ Si}[/tex]

Multiply by the value of atoms given.

[tex]1.5 \times 10^{21} \ atom \ Si *\frac { 6.022 \times 10^{23} \ atom \ Si }{1 \ mol \ Si}[/tex]

Flip the ratio. This allows the atoms of silicon units to cancel and leave the moles of silicon.

[tex]1.5 \times 10^{21} \ atom \ Si *\frac {1 \ mol \ Si } {6.022 \times 10^{23} \ atom \ Si}[/tex]

[tex]1.5 \times 10^{21}*\frac {1 \ mol \ Si } {6.022 \times 10^{23} }[/tex]

[tex]\frac {1.5 \times 10^{21} \ mol \ Si } {6.022 \times 10^{23} }[/tex]

[tex]0.002490866822 \ mol \ Si[/tex]

2. Convert Moles to Grams

Next, we convert the moles to grams. We use the molar mass, which is found on the Periodic Table. This value is the number of grams in 1 mole of a substance. Look for silicon (Si).

Si: 28.085 g/mol

Use this value as a ratio.

[tex]\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]

Multiply by the number of moles we calculated.

[tex]0.002490866822 \ mol \ Si *\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]

The moles of silicon units cancel, so we are left with grams.

[tex]0.002490866822 *\frac {28.085 \ g \ Si}{1}[/tex]

[tex]0.002490866822 *{28.085 \ g \ Si}[/tex]

[tex]0.06995599469 \ g \ Si[/tex]

3. Round

Finally we must round our answer. The original value has 2 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place.

[tex]0.069\underline95599469 \ g Si[/tex]

The 9 tells us to round the other 9 to a 0, then the 6 to a 7.

[tex]0.070 \ g \ Si[/tex]

The mass of 1.5 × 10²¹ silicon atoms is 0.070 grams of silicon.

When answering this question include the following:

Have both the unbalanced and balanced chemical equations.
Explain how to find the molar mass of the compounds.
Explain how the balanced chemical equation is used to find the ratio of moles (hint: step 3 in the video).
Explain how many significant figures your answer needs to have.
The numerical answer
Your Answer:

Answers

Answer:

See Explanation

Explanation:

The unbalanced reaction equation is;

CO2(g) + LiOH(aq) + Li2CO3(aq) + H2O(l)

The balanced chemical reaction equation;

CO2(g) + 2LiOH(aq) + Li2CO3(aq) + H2O(l)

The molar mass of each compound is the sum of the relative atomic masses of the atoms of the elements that compose the compounds.

For CO2

12 + 16(2) = 12 + 32 = 44 g/mol

For LiOH

7 + 16 + 1 = 24 g/mol

For Li2CO3

2(7) + 12 + 3(16) = 74 g/mol

For H2O

2(1) + 16 = 18 g/mol

From the balanced chemical reaction equation, the mole ratio is 1:2:1:1. This is obtained from the stoichiometric coefficient of each reactant in the balanced chemical reaction equation.

From the question;

1 mole of CO2 occupies 22.4 L

x moles of CO2 occupies 825 L

x = 1 mole * 825 L/22.4 L

x = 36.8 moles

From the reaction equation;

1 mole of CO2 produces 1 mole of water

36.8 moles of CO2 produces 36.8 moles of water

Mass of 36.8 moles of water = 36.8 moles * 18 g/mol

= 662 g of water

The answer must have three significant figures because that is the same number of significant figures to which values were given in the question.

A chemist makes 380. mL of magnesium fluoride (MgF2) working solution by adding distilled water to 20.0 mL of a 18.8 L stock solution of magnesium fluoride in water.

Calculate the concentration of the chemist's working solution.

Round your answer to 3 significant digits

Answers

Answer:

0.99 μmol/L

Explanation:

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

Volume of stock solution (V₁) = 20 mL

Concentration of stock solution (C₁) = 18.8 μmol/L

Volume of diluted solution (V₂) = 380 mL

Concentration of diluted solution (C₂) =?

The concentration of the diluted solution can be obtained as follow:

C₁V₁ = C₂V₂

18.8 × 20 = C₂ × 380

376 = C₂ × 380

Divide both side by 380

C₂ = 376 / 380

C₂ = 0.99 μmol/L

Therefore, the concentration of the diluted solution the chemist is working on is 0.99 μmol/L
