Answer: mass of oxygen is needed to react with 10g of hydrogen is
Explanation:Calculation:
- The reaction of oxygen with hydrogen is depicted as:
H2 + 1/2 O2 → H20
- From the above reaction, we can calculate the mass of oxygen as:
Mass of oxygen required to react with 2 gm hydrogen = 16 gm
⇒ Mass of oxygen required to react with 10 gm hydrogen = (16/2) × 10
⇒ Mass of oxygen = 80 gm
- According to the given amounts, mass of water formed = 10 + 80 = 90 gm
- No of moles of water in 90 gm = 90/18 = 5 moles
- The volume of 5 moles of water = 22.4 × 5
⇒ The volume of 5 moles of water = 112 Litre
- Hence, 80 gm of oxygen is required to react with 10 gm of hydrogen and 112 L of water is formed on this reaction.
