Answer:
5.8 moles of copper are needed to react with sulfur to produce 2.9 moles of copper (I) sulfide.
Explanation:

Moles of copper(I) sufide = 2.9 mol
According to reaction, 1 mole of copper(I) sulfide is obtained from 2 moles of copper, then 2.9 moles of copper(I) sulfide will be obtained from :
copper
5.8 moles of copper are needed to react with sulfur to produce 2.9 moles of copper (I) sulfide.

Answer:
As a substance changes from a solid to a liquid to a gas, its molecules first the molecules are moving fast enough, they are able to "escape." They leave the surface of the liquid as gas molecules.

Answer:
A hot air balloon uses a burner to heat up the air inside the balloon. The burner is usually fueled by liquid propane. The burner mixes the fuel with air and ignites the mixture, which creates a flame directly underneath the bottom opening of the hot air balloon. Once the air inside the balloon begins to get warm, the balloon will rise. The pilot controls the balloon’s altitude by releasing hot air from a vent at the top of the balloon, releasing the warmer air causes the balloon to descend.
