?_N2 + _? O2 → _?_ NO2 balance the equation and determine the correct lowest mole ratio.
If 5 moles of N2 reacted with 12 moles O2

How many moles NO2 are produced?
How many moles of O2 are left ? How many moles of N2 are left?

Using the periodic table, complete the following. element: hydrogen symbol: h₂ molecular weight: g mass of one mole: g/mol

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.

Volume is a measurement of how fast particles of a substance are moving
