Answer:
i.
A kid falling out of a tree - Gravitational Potential energy to Kinetic energy
ii.
A scout rubbing sticks together to start a fire - Kinetic energy to Heat energy
iii.
A man running a kerosene heater - Chemical Potential energy to Heat energy
Chlorine is diatomic but sodium is not
Answer:
No
Explanation:
It is given that :
Amount of the clear aqueous solution = 4 L
Temperature of the clear solution = 22°C
The solution remain clear even after an unknown amount of X compound is dissolved in the solution.
Then the water is evaporated under vacuum and the remaining precipitates weighs 0.56 kg.
Therefore, from the above data, we cannot calculate the solubility of the compound X that is added to the clear aqueous solution at 22°C.
The substance which gets dissolved is known as solute and the substance where the solute is dissolved is known as the solvent.
Hard question thx for the points
