4. Air is made up of gas particles. These particles exert pressure on every object they collide against. This pressure is known as air pressure.

In a gas stove, propane (C3H8) is mixed with oxygen gas (O2) from the air and ignited to burn. The products of the reaction are given off as gases and consist primarily of carbon dioxide (CO2) and water (H2O).

In 1901, Thomas Edison invented the nickel-iron battery. The following reaction takes place in the battery. Fe (s) + 2 NiO (OH) (s) + 2 H2O (l) Fe (OH) 2 (s) + 2 Ni (OH) 2 (aq) How many mole of Fe (OH) 2, is produced when 5.35 mol Fe and 7.

As you move from left to right across the periodic table, the atomic numbers increase decrease stay the same are random

Use the octet rule to predict the formula of the compound that would form between fluorine and iodine, if the molecule contains only one fluorine atom and only single bonds are formed.
