Answer:
CH4 + 2O2 → CO2 + 2H2O Incomplete combustion – carbon monoxide and water. Ex. 2CH4 + 3O2 → 2CO + 4H2O The amount of oxygen present and the temperature determine whether the reaction is complete or incomplete.
The weight of a solid gold crown would be much heavier than one if not made of solid gold. It would also not tarnish as quickly as one of other metals.
Hope this helped!
It's A; decomposition reactions involve one reactant becoming 2 or more products.
1. Exothermic, because it’s giving off heat
2. Exothermic, because it’s giving off heat
3. Endothermic, because it’s losing heat
Answer:
Explanation:
Word equation:
sulfuric acid + ammonium hydroxide → ammonium sulfate + water
Chemical equation:
H₂SO₄ + NH₄OH → (NH₄)₂SO₄ + H₂O
Balanced chemical equation:
H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + 2H₂O
The given reaction is the reaction of acid with base. When acid and base react salt and water are produced. In given reaction an acid sulfuric acid and base ammonium hydroxide react and form ammonium sulfate salt and water. The given reaction also follow the law of conservation of mass.
Steps to balance the equation:
Steps 1;
H₂SO₄ + NH₄OH → (NH₄)₂SO₄ + H₂O
H = 7 H = 10
S = 1 S = 1
O = 5 O = 5
N = 1 N = 2
Step 2:
H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + H₂O
H = 12 H = 10
S = 1 S = 1
O = 6 O = 5
N = 2 N = 2
Step 3:
H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + 2H₂O
H = 12 H = 12
S = 1 S = 1
O = 6 O = 6
N = 2 N = 2
