Answer:
Explanation:
2HCl = H₂ + Cl₂
2 mole 1 mole 1 mole
73 gram HCl = 73 / 36.5 = 2 mole of HCl
2 moles of HCl will produce 1 mole of chlorine gas .
At STP , one mole of chlorine gas has volume equal to 22.4 litre .
If it is incomplete or complete combustion. Normally the problems question with tell you.
EX:
"In the presence of plenty of oxygen" is complete combustion
"Not enough oxygen present" is incomplete combustion

Answer:
The water would be neutral, (usually 7). The salt water would be the same (7) and the vinegar would be very acidic. (probably 2).
Explanation:
2H₂₍g₎ + O₂ ₍g₎→ 2H₂O
138 mol H₂ × (2 mol H₂O ÷ 2 mol H₂)= 138 mol H₂O
64 mol O₂ × (2 mol H₂O ÷ 1 mol O₂)= 128 mol H₂O
128 mol H₂O
