Answer:
30ft²
Explanation:
The area of the plywood that she has:
8 ⋅ 9
=72ft²
The area of the plywood she cut
7 ⋅ 6
=42ft²
The area discarded should be:
72ft² - 42ft²
= 30ft²
One mole of CH₄ reacts with<em> two moles </em>of O₂, producing <em>one mole</em> of CO₂ and<em> two moles</em> of H₂O. Also, one molecule of CH₄ reacts with<em> two molecules </em>of O₂, producing one molecule of CO₂ and<em> two molecules </em>of H₂O.
<h3>
Balance chemical equation</h3>
A balanced chemical equation tells the amounts of reactants and products needed to satisfy the Law of Conservation of Mass.
CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g).
From the chemical combustion of methane given above, One mole of CH₄ reacts with<em> two moles </em>of O₂, producing <em>one mole</em> of CO₂ and<em> two moles</em> of H₂O. Also, one molecule of CH₄ reacts with<em> two molecules </em>of O₂, producing one molecule of CO₂ and<em> two molecules </em>of H₂O.
