It is known that 1 mol of a substance is equal to 6.02x10^3 particles. This is called the Avogadro's number. From this knowledge, we convert the mass of the substances given above into units of moles by using the molar mass.
12.01 g C ( 1 mol / <span>12.01 g) = 1 mol
44.08 g SiO2 ( </span>1 mol / <span>60.08 g ) = 0.73 mol
16 g of O3 (</span>1 mol / <span>48 g) = 0.33 mol
16.04 g CH4 (</span>1 mol / <span>16.05 g ) = 0.99 mol
So, the answers are carbon and </span><span>carbon tetrahydride</span>.
Answer:
Explanation:
We can use Gay-Lussac's Law of Combining Volumes to solve this problem.
Gases at the same temperature and pressure react in the same ratios as their coefficients in the balanced equation.
1. Write the chemical equation.
Ratio: 1 L 3 L
N₂ + 3H₂ ⟶ 2NH₃
V/L: 2
2. Calculate the volume of H₂.
According to Gay-Lussac, 3 L of H₂ react with 1 L of N₂.
Then, the conversion factor is (3 L H₂/1 L N₂).
Answer:
she should not have multiplied the sulfur atoms by the subscript 4
Explanation:
Answer:
It could pollute other planets. Nuclear waste might be attracted by the gravitational pull of the sun and disintegrate there instead. The waste storage spacecraft could crash into a planet, moon, or another astronomical body. It could be dangerous for other life forms out there.
