Answer:
heat from the sun and heat flowing out of earth as it cools.
Answer:
CH₄ + 2O₂ → 2H₂O + CO₂
Explanation:
From the given problem;
White balls = hydrogen
Black balls = carbon
Gray balls = oxygen
Equation of the reaction:
1 carbon atom surrounded by 4 hydrogen + 2 oxygen molecules gives two hydrogen atoms bonded to one oxygen + 1 carbon atom bonded to two oxygen
CH₄ + 2O₂ → 2H₂O + CO₂
The reaction above is balanced.
Answer:
.56 liters
Explanation:
(.025 mol) * (22.4 L/1 mol) = .56 L
Let the unknow oxidation number b x
1+x+3(-2)=0
x-5=0
x=5
Because the decomposition is the reverse process of the formation.
Enthalpy is a function of state, which means that the value dependes only on the state and not the pathway.
Then the change of enthalpy is the same in magnitude for both cases but in formation the change is netavie (releases energy) and in the other is postive (absorbs energy).
