Hey there!
(i) Light production in fireflies is due to a type of chemical reaction called bioluminescence. This process occurs in specialized light-emitting organs, usually on a firefly's lower abdomen. The enzyme luciferase acts on the luciferin, in the presence of magnesium ions, ATP, and oxygen to produce light.
(ii) Substance X is calcium hydroxide (Ca(OH)2) which reacts with carbon dioxide to give calcium carbonate.
Reaction is given as under:
Ca(OH)2 + CO2 ----------> CaCO3 + H2O
(iii) We store silver chloride in dark coloured bottles in order to protect it from the effect sunlight.
Sunlight can decompose silver chloride and make it silver and chlorine. So, if we store silver chloride in normal bottles, we may not find our silver chloride later.
Hope it help
