g Though wizards might be able to manage without air-bags, Muggles certainly need them! Air-bags can be inflated by the decomposition of sodium azide, NaN3. At 25.0◦C and 1.10 atm, what volume of N2 (g) is produced by the decomposition of 71.

What is R in the ideal gas law equation

Hat information is needed to determine the energy of an electron in a many-electron atom?

What are the 3 types of potential energy?

What is a potential benefit of fuel cell cars? increased efficiency converting gasoline to energy no recharging necessary decreased automobile cost larger engines

Water is a great solvent. For example, it causes ionic compounds like sodium chloride (table salt) to dissociate. One of these reasons that water does is because it is polar molecule.

For most compounds with a single keto group in the molecule, equilibrium favors the keto form over the enol form of the compound. this is due largely to what?

The partial negative charge in a molecule of water occurs because the electrons shared between the oxygen and hydrogen stoms spend more time around the oxygen atom nucleus than around the hydrogen atom nucleus?

An electron moved from a higher energy level to a lower energy level. What most likely happened during the transition?
