Answer:
The answer to your question is 0.35 moles of ZnCl₂
Explanation:
Data
moles of ZnCl₂ = ?
mass of Zn = 23 g
mass of CuCl₂ = excess
Balanced chemical reaction
Zn + CuCl₂ ⇒ ZnCl₂ + Cu
Process
1.- Convert the mass of Zn to moles
-Look for the atomic mass of Zn
Atomic mass = 65.4 g
-Convert the grams to moles
65.4 g -------------- 1 mol
23 g ---------------- x
x = (23 x 1)/65.4
x = 23 / 65.4
x = 0.35 moles of Zn
2.- Calculate the moles of ZnCl₂ using proportions and cross multiplication, and the coefficients of the balanced chemical reaction.
1 mol of Zn ---------------- 1 mol of ZnCl₂
0.35 moles of Zn -------- x
x = (0.35 x 1) / 1
x = 0.35 moles of ZnCl₂
The mass of water is equal to the combined mass of hydrogen and oxygen.
<h3>What is Mass?</h3>
This is defined as the quantity of matter in a physical body. The electrolysis reaction of water can be seen below:
2 H₂O ---> 2 H₂ + O₂
We can deduce that 36 grams of H₂O dissociated to give 4 grams of H₂ and 32 grams of O₂ which option D was chosen as the appropriate choice.

This will be classified as light on the API scale due to the large percentage of lighter fractions such as paraffins and naphthenes.
