C2H5OH(g) + 302(g) → 2CO2(g) + 3H2O(g) + heat
reaction type
1 answer:
Answer:
Combustion
Explanation:
The reaction type is a combustion reaction;
Ethanol + oxygen gas → carbon dioxide + water
Now;
Ethanol is the fuel and oxygen gas rapidly combines with it to form carbon dioxide and water.
- This process releases heat energy from chemical bonds.
- Most hydrocarbons burn in excess air or oxygen to give carbon dioxide and water.

Answer: 1.6L
Explanation:
V1 = 1.50 L,
V2 =?
n1 = 3mol
n2 = 3 + 0.2 = 3.2mol
From PV = nRT
V1 /n1 = V2/n2
1.5/3 = V2 /3.2
V2 = (1.5/3/) x 3.2 = 1.6L

Explanation:
mass of solute(KBr) = 3.73g
mass of solvent(H2O) = 131g
mass of solution = mass of solute + mass of solvent
= 3.73 + 131
= 134.73g
Answer: 4.15234 m
512 g H2O * 
= 0.512 kg H2O
Nitric Acid: HNO3 = 1.008 + 14.007 + 3(15.999) = 63.012 g/mol
H = 1.008 g/mol
N = 14.007 g/mol
O3 = 3*15.999
134 g HNO₃ * 
= 2.126 mol
m = 
= 4.15234 m
