Why does temperature stay constant during a phase change?

Serjik [45]

When a solid is heated , the average kinetic e energy of the substance increases because of which the temperature increases....this heat won’t affect the average kinetic energy of the substance. Since average kinetic energy will remain same during phase change , the temperature will remain same too.

100.0 grams of sucrose (C12H22O11)is dissolved in 1.50 L of water. What is the molality?

Nitella [24]

Answer:

Molality = 66.67g/L

Explanation:

Mass of sucrose = 100g

Volume of water = 1.50L

Molality = mass of substance/ volume in L

Molality = 100 / 1.50

Molality = 66.67g/L

Molality of 100g of sucrose in 1.50L of water is 66.67g/L

xxTIMURxx [149]

Answer:

0.374 g

Explanation:

Hello,

Since both the molarity and the volume allows us to know the moles of potassium permanganate, and we already have the balanced chemical reaction, the stoichiometric procedure that is attached in the picture, is developed to substantiate the the titrated mass of hydrogen peroxide was 0.374 g.

Best regards.
