Which law of chemical combination will govern your ans
3. What are polyatomic ions? Give examples.
Write the chemical formulae of the following.​

Answer 1

ANSWER-

2. When 3.0g of carbon is burnt in 8.00 g of oxygen, 11.00 g of carbon dioxide is produced. Carbon and oxygen are combined in the ratio 3:8 to give 11 carbon dioxide . Hence, for 3g of carbon and 50g of oxygen, 8g of oxygen is used and 11g of carbon is formed, and 42g of oxygen is unused. This is govern by law of definite proportions.

3. Polyatomic ions are ions that contain more than one atom but they behave as a single unit. Example: OH
