<u>mass of reactants = mass of products</u> best represents the law of conservation of mass
Explanation:
This is a law of thermodynamic that applies to chemical reactions. The mass of the reactants must equal to that of the products because energy/mass cannot be destroyed or created. This is why ideally, chemical reactions should be balanced to conform to this law.
Answer
12
Explanation
We have a balanced chemical equation from the question that depicts the formation of water.
2H2+O2-->2H2O,
We can clearly see from the equation that, the formation of 2 moles of water molecules requires the input of 2 moles of hydrogen and 1 mole of Oxygen.
So indirectly, it tells that the moles of water molecules will be double of the moles of Oxygen molecules used in the reaction.
So if we say that 6 moles of oxygen is used and the reaction is going in such a way that hydrogen is not a limiting reactant, then 12 moles of water will be produced.
Hope it help!
A) 2H₂(g) + O₂(g) → 2H₂O(l) + 285.83 kJ
Exothermic
B) 2Mg + O₂ → 2MgO + 1200kJ
Exothermic
