I prepared a little experiment about solid rocket propulsion. I have used water ($H_{2}O$), potassium nitrate ($KNO_{3}$) and saccharose ($C_{12}H_{22}O_{11}$).
I made the mixture in a pan by cooking it. I put 100ml of water into the pan. Then I added 50g of potassium nitrate and 100g of saccharose at the same time when the water boiled up. I started to mix it using a spoon and it took like 35-40 minutes to water evoporation. After the cooking there is only a mixture of dough consistency solid left. It had a light-yellow colour.
When the mixture got cold I wanted to test it. I took a little piece of it and then start the fire, it burned like firewoek.
I wonder the equation of the mixture after it mixed. I mean,
$$KNO_{3}(s) + C_{12}H_{22}O_{11}(s) + H_{2}O(l) \rightarrow \dots \text{(Result 1)(s)}$$
And the after burn result of the combustion.
$$\text{(Result 1)(s)} + heat \rightarrow \dots \text{(Result 2)}$$
I hope I gave you enough informations about the mixture and combustion.
