Answer: Moles of hydrogen required are 4.57 moles to make 146.6 grams of methane,
.
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](https://tex.z-dn.net/?f=Moles%20%3D%20%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D%5C%5C%3D%20%5Cfrac%7B146.6%20g%7D%7B16.04%20g%2Fmol%7D%5C%5C%3D%209.14%20mol)
The given reaction equation is as follows.
![C + 2H_{2} \rightarrow CH_{4}](https://tex.z-dn.net/?f=C%20%2B%202H_%7B2%7D%20%5Crightarrow%20CH_%7B4%7D)
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](https://tex.z-dn.net/?f=Moles%20of%20H_%7B2%7D%20%3D%20%5Cfrac%7B9.14%7D%7B2%7D%5C%5C%3D%204.57%20mol)
Thus, we can conclude that moles of hydrogen required are 4.57 moles to make 146.6 grams of methane,

Answer:
on the surface of the cathode
before the lava rises to the earth's surface it's called magma. Although lava and magma are often used interchangeably, technically magma is the name for the hot molten rock (mixed with gases and mineral crystals) that collects in chambers beneath the Earth's crust.
Explanation:
Answer:
A. The forces in gases are weaker than forces in solids but stronger
than forces in liquids.
