Answer:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).
Explanation:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
2H₂O(g) → 2H₂O(l)
- To add the two equations: we omit H₂O(g) that is formed by 2 moles in the product side of the first equation and consumed by 2 moles from the reactants side in the second equation
- So, the overall chemical equation is obtained by combining these intermediate equations is:
<em>CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).</em>

Answer:
Yes
Explanation:
Chemical equation:
CuO + H₂ → Cu + H₂O
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given reaction:
CuO + H₂ → Cu + H₂O
there are 1 copper atoms, one oxygen atoms and two hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
Mercury, Earth and Mars
Explanation:
From the given list, only Venus is not an inner planet.
Inner planets are also known as terrestrial planets. They are rocky planets with very high density. These planets are close to the sun. These planets are Mercury, Venus, Earth and Mars.
The outer planets are the gas giants. They are predominantly made up of gases. They are also called Jovian planets. They are not as dense as the Inner planets. These planets are Jupiter, Saturn, Uranus and Neptune.
