In a couple of paragraphs, explain to a younger student why it rains sometimes (and why at other times it doesn't). What would you say to help him or her understand? Be sure to talk about moisture in the atmosphere and temperature changes. What other factors might be helpful to discuss.

Please don't write the whole essay, just start me off :)

In the reaction between a crushed antacid tablet and vinegar what gas is emitted

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

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.)
