For a chemical reaction to occur the reactant particles must collide with each other with the correct orientation and they must also have a minimum energy necessary for the molecules to successfully react...

The activation energy is the minimum amount of energy that particles need to collide with for the reaction to occur.

Ionic bonding involves ionic bonds forming between a metal and a non- metal (show where metals and non- metals lie on the periodic table) and electrons are transferred. The structure of this ionic compoun...

Empirical formula is the simplest whole number ratio of atoms of each element in a compound. With the empirical formula and relative molecular mass, we can determine the actual molecular formula of a comp...

The Earth's atmospheric oxygen increased because plants and algae developed and used carbon dioxide for photosynthesis. This led to a decrease in atmospheric carbon dioxide levels. The origins of the ocea...
