Year 10, writing fully balanced chemical equations homework

A whole lot of the chemistry you have studied this year comes together in this exercise.

  • ions and how they are formed.
  • naming ionic compounds and writing their formula
  • word equations.

…….. and finally the last piece in the jigsaw writing a fully balanced chemical equation.

If you study NCEA chemistry at level 1 next year a rough guide is

Achievement: writing word equations.

Merit: Inserting chemical formulae into an equation.

Excellence: producing a fully balanced chemical equation.

Revise what we did today by watching the video then do the short exercise. In your notebook write down the word equation and complete it (achievement) Underneath the word equation insert the chemical formula of each substance (merit). Finally balance the equation (excellence) NOTE this usually involves sticking 2 in front of something

1 sodium hydroxide      +   sulphuric acid             ——->

2 copper oxide                 +  hydrochloric acid     ——–>
