Answer: The correct option is 2.

Explanation: Polyatomic ions are defined as the ions in which two or more elements are covalently bonded to act as a single unit. They always carry some charge.

Examples of polyatomic ions are: OH^- known as hydroxide ion, SO_4^{2-} known as sulfate ion

We are given a compound NaHCO_3 having 2 ions which are Na^+ and HCO_3^-. these ions are named as sodium ions and hydrogen carbonate ions.

Therefore, the correct option is 2.

What is the mole fraction of methanol in a solution that contains 6.0 mol of methanol and 3.0 mol of water? The formula for meth
Ivenika [448]
The mole fraction of a product is the number of moles of the product divided by the total number of moles of the solution.

Here moles of methanol = 6.0 moles

Moles of solution = 6.0 moles of methanol + 3.0 moles of water = 9.0 moles of solution

Mole fraction of methanol = 6.0 / 9.0 = 0.67
