Answer:
219.1K
Explanation:
T1/V1= T2/V2
Temp for Gas Laws are always in Kelvin

so T2= (T1xV2)/V1
(35Lx313K)/50L=219.1K

Answer:
126 g of H₂O
Explanation:
Firstly, we complete the equation:
2H₂ + O₂ → 2H₂O
If we have 7 moles of hydrogen, we assume, the oxygen is in excess.
Ratio is 2:2.
2 moles of hydrogen can produce 2 moles of water
Then, 7 moles of H₂ must produce 7 moles of water.
We convert moles to mass → 7 mol . 18 g/mol = 126 g
