The action force when a rocket rises is caused by the rocket expelling gas out of its engine.<span> The rocket reacts by moving in the opposite direction and lifting off from the launch pad.</span>
Answer: Yes, it is possible for each samples to contain 1 mole of a substance because the number of moles are not dependent on the mass or the volume.
Explanation:
The formula for the number of moles is given by:
As, the masses of 2 samples are different, so the number of moles will be dependent only on the molar masses of the samples.
Volume has no effect on the number of moles.
Answer:
Neon and Methane
Explanation:
Nitrogen and Oxygen made up way over half of the atmosphere so it's without a doubt, not those two. Precisely, Nitrogen makes up 78% of the atmosphere while oxygen makes up 21%
Uh I can help you with the converting into moles, 50 grams= 2.775421, sorry if I didn’t help much :/
PCl₅ reacts upon contact with water to launch hydrogen chloride and supply phosphorus oxides. the primary hydrolysis product is phosphorus oxychloride PCl₅ + H₂O ========> POCl₃ + 2HCl.
Phosphorus trichloride appears as a colorless or slightly yellow fuming liquid with a pungent and irritating odor resembling that of hydrochloric acid. Causes severe burns to skin, eyes and mucous membranes.
Divide the mass of the material through its molar mass. The molar mass of a substance is the mass in grams of 1 mole of that substance. This mass is given via the atomic weight of the chemical unit that makes up that substance in atomic mass units.
One mole is described as the amount of substance containing as many number one entities atoms, molecules, ions, electrons, radicals, and lots of others. As there are atoms in 12 grams of carbon - 12(6. 023×10²³. The mass of one mole of a substance equals to its relative molecular mass expressed in grams.
