Question

pls say me the answers​

Answer 1

Answer:

1. 1

2. 35.453 u

3. is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant. The atomic mass constant (symbol: mu) is defined as being 112 of the mass of a carbon-12 atom.

4. A solute is the substance to be dissolved (sugar). The solvent is the one doing the dissolving (water).

5. Ksp= (A±)à(B-)b

6. Normally, oxygen solubility is strongly dependent on (1) the amount of dissolved electrolyte salt(s) (decreases at higher concentration of electrolyte), (2) temperature (decreases at higher temperatures), and (3) pressure (increases at higher pressure).

Answer 2

1) Atomicity of sodium is 11.

2) Molecular mass of chlorine is 35.4.

3) Relative atomic mass is also known as atomic weight.

4) Solute in sugar solution is sugar.

5) Solubility = Amount of solute + Dissolved solvent.

6) Temperature increases solubility of oxygen is endothermic.
