What causes air masses to move? A difference in air pressure and temperature occurs.
Weather conditions change rapidly to produce storms.
A collision takes place between two natural wind patterns.
Long, narrow bands of wind blow in the upper atmosphere.

Determine the empirical formula of a compound containing 40.6 grams of carbon, 5.1 grams of hydrogen, and 54.2 grams of oxygen. in an experiment, the molar mass of the compound was determined to be 118.084 g/mol. what is the molecular formula of the compound? for both questions, show your work or explain how you determined the formulas by giving specific values used in calculations.

How could a student test the effect of removing heat from a gas that is stored in a sealed container? what must occur in order for matter to change states?

If 16.00g of hydrogen gas reacts with 126.73g of oxygen, how many grams of water are yielded? (both reactants are completely consumed in the reaction.)
