Answer:
The solubility of a substance can be increased by increasing the amount of solvent in a solution.
Explanation:
Two ways by which the rate of dissolving for substance can be increased.
1 By increasing the temperature of the solution: Increase in temperature will in turn increase the entropy or disorder or randomness of the solute molecules in a solution thus increasing the rate of dissolving the substance in that solution.
2 By increasing the volume of the solution : increase in the volume of the solution by adding more solvent can also increase the dissolving rate of a specific substance in a solution.
Answer:
On the farm there are 70 chickens.
Explanation:
We can directly <u>work out the number of ducks from the given number of pigs</u>, with the <em>ratio of ducks to pigs</em>:
- 36 pigs * = 20 ducks
Then we<u> work out the number of chickens</u>, using the ration of chickens to ducks:
- 20 ducks * = 70 chickens
If on the farm there are 36 pigs, there are 70 chickens as well.
