Answer:
The answer to your question is 3.5 moles of H₂
Explanation:
Data
moles of H₂ = ?
moles of Zn = 3.5 moles
moles of HCl = excess
Process
1.- Write the balanced chemical reaction
Zn + 2HCl ⇒ ZnCl₂ + H₂
Reactants Elements Products
1 Zn 1
2 Cl 2
2 H 2
2.- Use the coefficients of the balanced reaction to calculate the moles of H₂
1 mol of Zn ----------------- 1 mol of H₂
3.5 moles of Zn ------------- x
x = (3.5 x 1)/1
x = 3.5 moles of H₂
Answer:
B
Explanation:
CH4 + O2 →H2O + CO2
Left side
C = 1
H = 4
O = 2
Right side
C = 1
H = 2
O = 3
So find common denominator in this case would be 6 O
CH4 + 3O2 →2H2O + CO2
Left side
C = 1
H = 4
O = 6
Right side
C = 1
H = 4
O = 6
