If you are given only the amount, in moles, of an unidentified chemical quantity, you can calculate the number of: representative particles in the sample atoms in the sample molecules in the sample particles, atoms, and molecules

How many moles of air are there in a human lung with a volume of 2.4 l at stp? explain your answer

Helium decays to form lithium. which equation correctly describes this decay?

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
