This reaction uses 24.1 g of copper(I) sulfide. Determine the volume of sulfur dioxide gas that would be collected at 237°C and 10.7 atm.
___Cu2S (s) + ___O2 (g) → ___Cu2O (s) + ___SO2 (g)

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?

A5.000 g sample of niso4 h2o decomposed to give 2.755 g of anhydrous niso4. what is the formula of the hydrate? what is the full chemical name for the hydrate? what is the molar mass of the hydrate? niso4•_h2o what is the mass % of water in the hydrate?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
