Alkenes — practice question
Some symbol equations and word equations, A to J, are given below.
A $\text{H}^+ + \text{OH}^- \rightarrow \text{H}_2\text{O}$
B $\text{Cr}^{3+} + 3\text{OH}^- \rightarrow \text{Cr(OH)}_3$
C methane + chlorine → chloromethane + hydrogen chloride
D propene + bromine → 1,2-dibromopropane
E $\text{C}_{10}\text{H}_{22} \rightarrow \text{C}_8\text{H}_{18} + \text{C}_2\text{H}_4$
F chlorine + aqueous potassium bromide → bromine + aqueous potassium chloride
G methane + oxygen → carbon monoxide + water
H $\text{C}_2\text{H}_5\text{COOH} + \text{CH}_3\text{OH} \rightarrow \text{C}_2\text{H}_5\text{COOCH}_3 + \text{H}_2\text{O}$
I hydrogen + oxygen → water
J $6\text{CO}_2 + 6\text{H}_2\text{O} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2$
Work through the equations to answer the questions that come next.
Each equation may be chosen once, used more than once, or not chosen at all.
Write the letter, A to J, for the equation that shows:
