11 gm calcium carbonate reacts with dil Hydrochloric acid.
No. of `CO_2` molecules produced?

What is the amount of CO_2 will be produced from 10gm CaCO_3 reacting with hydrochloric acid? How many molecules of CO_2 will be produced.

Excess of carbon dioxide is passed through 50 mL of 0.5 M calcium hydroxide solution. After the completion of the reaction, the solution was evaporated to dryness. The solid calcium carbonate was completely neutralised with 0.1 N hydrochloric acid. The volume of hydrochloric acid required is (Atomic mass of calcium = 40)

Why is the CO_2 molecule non polar?

Explain the structure of CO_(2) molecule.

KMnO_4 oxidises oxalic acid in acid medium. Calculate the number of CO_2 molecules produced as per the balanced equation.

Calcium carbonate reacts with aqueous HCl to give CaCl_(2) and CO_(2) according to the reaction. CaCO_(3)(s) +2HCl (aq) to CaCl_(2)(aq)+CO_(2)(g)+H_(2)O(l) What mass of CaCO_(3) is required to react completely with 25 mL off 0.75 (M) HCl?

What is the mass of magnesium Chloride.and hydrogen formed when 36 gm of Magnesium reacts. With excess of hydrochloric acid? [Mg = 24, Cl = 35.5

Na_(2)O reacts with water to produce nitrous acid.

Methyl amine when reacts with HNO_2 produces
