Answer:

1. Sodium chloride is formed when sodium atoms interact with chlorine atoms. When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative. ... So then, sodium ions will attract chloride ions and form an ionic bond.
2. Roasting is a process of heating of sulphide ore to a high temperature in presence of air. ... During roasting, the sulfide is converted to an oxide, and sulfur is released as sulfur dioxide, a gas. For the ores Cu2S (chalcocite) and ZnS (sphalerite), balanced equations for the roasting are: 2 Cu2S + 3 O2 → 2 Cu2O + 2 SO.
3. (1) It is used as an antacid in medicine to remove acidity of the stomach. (2) It is used in making baking powder. Baking powder is a mixture of baking soda and a mild edible tartaric acid. When baking soda mixes with water,then sodium hydrogen carbonate reacts with tartaric acid to evolve carbon dioxide gas.
