Question

According to the following reaction, how many grams of chlorine gas are required for the complete reaction of 31.8 grams of bromine?

bromine (g) + chlorine (g) = bromine monochloride (g)

According to the following reaction, how many grams of hydrogen gas will be formed upon the complete reaction of 22.1 grams of water?

water (l) = hydrogen (g) + oxygen (g)

According to the following reaction, how many grams of water are required for the complete reaction of 25.4 grams of chlorine gas?

chlorine (g) + water (l) = hydrochloric acid (aq) + chloric acid (HClO₃) (aq)
