Answer:
Explanation:
Filtration can be used to separate an insoluble solid from a liquid, or a precipitate from the reaction mixture in which it formed. The solid which collects in the filter paper is called the residue. The clear liquid which passes through the filter paper is called the filtrate.
The answer is c this is the answer
Answer : The enthalpy change for dissolving this salt on a energy per mass basis is 132.4 J/g
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water
where,
q = heat released by the reaction
= heat absorbed by the calorimeter
= heat absorbed by the water
= specific heat of calorimeter =
= specific heat of water =
= mass of water =
= change in temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change for dissolving this salt on a energy per mass basis.
where,
= enthalpy change = ?
q = heat released = 331.08 J
m = mass of salt = 2.50 g
Therefore, the enthalpy change for dissolving this salt on a energy per mass basis is 132.4 J/g
Convection is when cool air sinks and warm air rises. i am not 100% sure though
The 2 parts or components that make up a solution would be the solute and the solvent.
