b. Fe(s)+CuSo4(aq)-> FeSO4 (aq) + Cu(S)
c. C1OH8(1)+120^2 (g) -> loCO2 (g)+ 4H2O(g)
d. NaCI (aq)+ AgNO3 (aq) -> NaNO3 (aq)+ AgCI(s)

e. NH4 NO3 (s) -> N2O (g) -> NaO(g)+2H2O(g)

1 combustion happens when oxygen reacts with a substance and creates energy in a form of energy and light.
 2 In a synthesis (combination) reaction, two atoms or compounds come together to produce one product. This is the opposite of a decomposition reaction, where one compound is pulled apart into two or more substances
3 i cant see the figure

4 One of the possible impacts of redox reactions can cause rust on economic objects. Due to this economic impact we could lessen these chemical reactions by controlling them.

12 i have no idea
