Question

10. 1.2044 X10 Xm = 2 n How many moles are in 1.2044 x 1024 molecules? 2.0000 moles 2 moles 4 moles d. 2.000 molecules 104 X mol 6,022xus Strong acids tend to do what? Donate hydroxide ions Donate H* ions in solution Produce OH ions 12. _amount of compared to stock solutions. Dilute solutions contain a small, solute small, solution large, solute C. 13. amount of solute compared to dilute solutions. Stock solutions contain a a larger solution smaller

Answer 1

10. 1 mole = 6.023 × 10^23 molecules

1.2044 × 10^24 molecules = 1.2044 × 10^24/ 6.023 × 10^23

Answer -- 2 moles

11. Those substances which give H+ ions is solution are called acids while those substances which give OH- ions in solution are called bases.

Strong acids give a large number of H+ ions in solution.

Answer -- donate H+ ions in solution

12. Those solutions which contains a large amount of solute are known as concentrated solutions while those solutions which contains a small amount of solute and large amount of solvent are known as dilute solutions.

Answer -- a. Small , solute

13. a. Large
