No party system is ideal for all countries and all situations because the party system is not what a country actually chooses. It evolves over a long time, depending on the nature of society, its social and regional divisions, its history of politics and its system of elections. These cannot be changed quickly. Each country develops a party system which is conditioned by its special circumstances. For example, if India has evolved a multi-party system, it is because the social and geographical diversity in such a large country is not easily absorbed by two or even three parties.
C. CO2 (i) and CaCO3 (ii)
is the answer.
Explanantion:
Sodium hydrogencarbonate on reaction with acetic acid releases carbon dioxide gas.
NaHCO3 + CH3COOH → CH3COONa + H2O + CO2
Test for CO2:
The presence of carbon dioxide can be tested by bringing a burning splinter near the mouth of the cylinder containing carbon dioxide – it gets extinguished.
If carbon dioxide is passed through limewater, it turns milky white.
Ca(OH)2 + CO2 → CaCO3 + H2O
