Answer:
1,2,3
Explanation:
Heat gain implies that heat is absorbed by the system in order to make the stated phase transition possible.
Before a liquid changes to gas, intermolecular forces in the liquid are broken by energy supplied as heat.
Also, transition from solid to liquid requires energy to break intermolecular bonds.
Finally, sublimation requires input of energy in the form of heat.
The answer is A. The volume lines on the bottom are just showing the volume of the beaker. The more dense liquid will sink to the bottom
Answer:
Explanation:
Hello!
In this case, since the melting process involves the heat added to the system, the heat of fusion and the mass of water:
Thus, as it has been reported that the heat of fusion of ice is 333.6 J/g, we can compute the melted mass of ice as shown below:
Thus, the ice leftover results:

First, need to know the formula of Molarity.
moles of solute
Molarity = ---------------------------
liters of solution
Given
2.0 liter of solution
58 grams of NaCl
Base of my research the moles of 58 grams of NaCl is 0.750 moles
Solution
0.750 moles
Molarity = ----------------------- = 0.375
2.0 L
The molarity of this solution is 0.375
