Question

1) what is formed when hydrogen burns ? write the equation for the reaction .

2) why do you think that, when hydrogen burns, the flame Rises quickly ?​

Answer 1

formed by burns rises quickly hydorogen

Answer 2

`H_2+\frac12O_2 \longrightarrow H_2O`

I don't think I need to name the product.

this reaction is very exothermic. so the gases and the flames are very hot, i.e. very lighter (hot air rises) than the normal air. so it rises quickly
