Answer:

24 mol Cu

General Formulas and Concepts:

<u>Chemistry</u>

  • Stoichiometry

Explanation:

<u>Step 1: Define</u>

RxN: 2Cu (s) + O₂ (g) → 2CuO (s)

Given: 12 moles O₂

<u>Step 2: Stoichiometry</u>

<u />12 \ mol \ O_2(\frac{2 \ mol \ Cu}{1 \ mol \ O_2} ) = 24 mol Cu

<u>Step 3: Check</u>

<em>We are given 2 sig figs.</em>

Our final answer is in 2 sig figs, so no need to round.

Why do oxygen and sulfur have similar chemical properties?
Step2247 [10]

Answer:

Oxygen and sulfur have similar chemical properties because both elements have six electrons in their outermost electron shells. Indeed, both oxygen and sulfur form molecules with two hydrogen atoms: water and hydrogen sulfide

A 10.0-g sample of sodium chloride was placed in 10.0 g of water. If 3.85 g of Cl2 was obtained, what was the percent yield of C
suter [353]

Answer:

63.53% yield

Explanation:

The balanced equation for this reaction is 2NaCl + H2O -> 2NaOH +Cl2

First we must find the limiting reactant

From NaCl we can only produce 6.06 grams of Cl2 in <u>theory</u>

From H20 we can only produce 38.995 grams in theory

so we know NaCl is the limiting

% yield is (Actual/Theoretical) x100 so

(3.85/6.06)x100= 63.53% yield

Hydrogen sulfide burns form sulfur dioxide:
Helga [31]

Answer: 404.04 kJ.

Explanation:

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

moles of H_2S

\text{Number of moles}=\frac{26.7g}{34.1g/mol}=0.78moles

2H_2S(g)+3O_2(g)\rightarrow 2SO_2(g)+2H_2O(g)    \Delta H=-1036kJ

According to stoichiometry :

2 moles of H_2S on burning produces = 1036 kJ

Thus 0.78 moles of H_2S on burning produces =\frac{1036kJ}{2}\times 0.78=404.04

Thus the enthalpy change when burning 26.7 g of hydrogen sulfide is 404.04 kJ.
