OH¯

82
Q

When do you need brackets for a formula?

A

You need brackets when an ion’s formula has more than 1 element in it and for that formula there needs to be more than 1 of that ion. Such as Al(OH)₃

83
Q

What are the 3 steps to a chemical equation:

A
  1. work out what the acid and base make then add water.
  2. Work out the chemical formulas for each reactant and product.
  3. Balance the equation. Draw bubbles (molecules) of the ions, balance each side. If you have added an extra set of an ion write the number of sets of that ion that you now have in front of its chemical formula.
84
Q

What happens in a chemical reaction?

A

In a chemical reaction atoms re-arrange themselves and form new chemicals. The number of atoms before and after is the same.
