Week 9 Reactions and Balanced Chemical Equations
Task 1 Writing Chemical Equations for Reactions
Revisit Friday's reactions in Week 8. You need to write equations for the three reactions that you performed.
Follow the rules for writing balanced equations;
(l) liquid
(g) gas
(aq) aqueous solution
Follow the rules for writing balanced equations;
- For each reaction write the reaction in words.
- Beneath each equation write the correct chemical formula for each reactant and product.
- Now balance the type and numbers of atoms/ions of each reactant and product.
- Write subscripts beneath each formula in your equation;
(l) liquid
(g) gas
(aq) aqueous solution
