The sum of all coefficients = 7
<h3>Further explanation</h3>
Given
The word equation
Required
The sum of all coefficients
Solution
The chemical equation can be expressed in terms of:
- word equation
- skeleton equation
- balanced equation
Convert the word equation into a chemical equation(skeleton) :
Ga + Cl₂ → GaCl₃
Balanced equation
2Ga + 3Cl₂ → 2GaCl₃
The sum of all coefficients :
= 2+3+2
= 7
Answer:
0.675 mol
Explanation:
Step 1: Write the balanced equation
2 Al + Fe₂O₃ ⇒ 2 Fe + Al₂O₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of Fe to Al₂O₃ is 2:1.
Step 3: Calculate the moles of Al₂O₃ produced when 1.35 moles of Fe are produced
We will use the established molar ratio.
1.35 mol Fe × 1 mol Al₂O₃/2 mol Fe = 0.675 mol Al₂O₃
Answer:
1.
%K = 31.904%
%Cl = 28.930%
%O = 39.166%
2.
Hg = 80.69/ 200.59 = 0.40/0.2 = 2
S = 6.436/ 32.07 = 0.20/0.2 = 1
O = 12.87/ 16.00 = 0.80/0.2 = 4
Hg2SO4 is the empirical formula
