Dependent Variable: The side effects (hallucinating and becoming delirious)
Answer:
4.50 g of H₂O
Explanation:
The Balance chemical equation is
2 H₂ + O₂ = 2 H₂O
Step 1: Calculate Limiting Reagent
Moles of H₂
Mole = 2 g / 2.02 g/mol = 0.99212 mol
Moles of O₂
Mole = 4 g / 32.00 g/mol = 0.125 mol
Mole ratio of H₂ : O₂ is 2 : 1. Hence, 0.99212 mol of H₂ will need 0.49606 mol of O₂. This means O₂ is limiting reagent.
Step 2: Calculate Moles of H₂O
0.125 mol of O₂ will produce 0.250 mol of H₂O because the mole ratio of O₂ : H₂O is 1 : 2.
Step 3: Calculate mass of H₂O
Mass = 0.250 mol × 18.02 g/mol = 4.50 g of H₂O
Answer:
Balanced Eqn
2C2H6 + 7O2 = 4CO2 + 6H2O
From the balanced equation
2((2*12)+(1*6)) of Ethane gave 6((1*2)+16)) of water
60g of Ethane. >. 108g. Of water
Xg > 1.61
X= 1.61*60/108
X= 0.89g
