Oxides of virtually every element are known. bromine, for example, forms several oxides when treated with ozone. suppose you allow 1.250 g of bromine, br2, to react with ozone, o3, and obtain 1.876 g of brxoy.

Of these gases, which has the fastest-moving molecules (on average) at a given temperature?

What is the oxidation number for zinc? How does zinc's electron configuration account for this oxidation number?

Which of the following experimental observations proved that the idea of matter and mass being evenly distributed in an atom was flawed? A. Less than 1% of the alpha particles went un-deflected through the gold foil. B.

Calculate the energy E of a sample of 3.50 mol of ideal oxygen gas (O2) molecules at a temperature of 310 K. Assume that the molecules are free to rotate and move in three dimensions, but ignore vibrations.

Gasohol is a fuel containing ethanol (c2h6o) that burns in oxygen (o2) to give carbon dioxide and water.
