The answer to this would be 22 mL
Here N H 4 O H { NH }_{ 4 }OH NH4OH is not a strong electrolyte because it doesn't dissociates completely.
Answer:
4.415 g of FeSO₄
Explanation:
The balance chemical equation for given single replacement reaction is as follow;
Fe + H₂SO₄ → FeSO₄ + H₂
Data Given;
Volume = 650 mL = 0.65 L
Density at STP = 0.08988 g/L
Mass = Density × Volume = 0.08988 g/L × 0.65 L = 0.0584 g
Step 1: <u>Calculate Moles of H₂ as; </u>
Moles = Mass / M.Mass
Moles = 0.0584 g / 2.01 g/mol
Moles = 0.0290 mol of H₂
Step 2: <u>Find out moles of FeSO₄ as;</u>
According to balance chemical equation,
1 mole of H₂ is produced along with = 1 mole of FeSO₄
So,
0.0290 moles of H₂ will be produced along with = X moles of FeSO₄
Solving for X,
X = 0.0290 × 1 mol / 1 mol
X = 0.0290 moles of FeSO₄
Step 3: <u>Calculate mass of FeSO₄ as;</u>
Mass = Moles × M.Mass
Mass = 0.0290 mol × 151.90 g/mol
Mass = 4.415 g of FeSO₄
I think it's 10 but i may not be right so, sorry if it's wrong lol
Answer:
11.55 mol ≈ 11.6 mol CO2
Explanation:
C3H8 (g) + 5O2(g) → 3CO2 (g) + 4H2O(g)
from reaction 1 mol 3 mol
given 3.85 mol x mol
Solving proportion
x =(3.85*3)/1 = 11.55 mol ≈11.6 mol
