Answer: Moles of hydrogen required are 4.57 moles to make 146.6 grams of methane, CH_{4}.

Explanation:

Given: Mass of methane = 146.6 g

As moles is the mass of a substance divided by its molar mass. So, moles of methane (molar mass = 16.04 g/mol) are calculated as follows.

Moles = \frac{mass}{molar mass}\\= \frac{146.6 g}{16.04 g/mol}\\= 9.14 mol

The given reaction equation is as follows.

C + 2H_{2} \rightarrow CH_{4}

This shows that 2 moles of hydrogen gives 1 mole of methane. Hence, moles of hydrogen required to form 9.14 moles of methane is as follows.

Moles of H_{2} = \frac{9.14}{2}\\= 4.57 mol

Thus, we can conclude that moles of hydrogen required are 4.57 moles to make 146.6 grams of methane, CH_{4}.

What is best classified as a physical change?
andrew-mc [135]

A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not. Physical changes can further be classified as reversible or irreversible. The melted ice cube may be refrozen, so melting is a reversible physical change.

In the balanced equation (picture included) how many moles of O2 MOLECULES and O2 ATOMS react?
tangare [24]

1) The answer is: 2 moles of oxygen molecules.

Balanced chemical reaction of methane combustion:  

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g).

Coefficients with the lowest ratio indicate the relative amounts of substances in a reaction.

In fronf of oxygen molecule is coefficient 2.

2) The answer is: 4 moles of oxygen atoms.

In one molecule of oxygen there are two oxygen atoms, so in two molecules there are four oxygen atoms.
