When a substance such as ice melts, its temperature increases. Describe what happens to the arrangement of the water molecules a
gogolik [260]

Answer:

The molecules absorb heat and acquire more kinetic energy.

Explanation:

In a solid, the solids only vibrate about their mean positions but do not translate. When energy is supplied to the molecule in the form of heat, the molecules vibrate faster. Eventually, they acquire sufficient energy to leave their mean positions and translate. Hence the solid crystal collapses.

When ice is heated, water molecules acquire sufficient kinetic energy to translate. The intermolecular bonds are gradually broken in the solid framework as heat is absorbed. The heat required for this is known as the latent heat of fusion.

The temperature remains constant until phase transition is over, then temperature rise resumes.

How many milliliters of a solution of 8.8M CaBr2 are needed to prepare 175 mL of a 2.2M solution?
patriot [66]

The product of molarity and volume of any substance at a fixed temperature is constant. Therefore comparing two portions of different molarity, we can say that, M₁V₁=M₂V₂

M represents the molarity, V represents volume of the solution.

M₁ in the question is 8.8M

M₂ is 2.2M

V₁=?

V₂= 175

therefore,

8.8ₓV₁= 2.2ₓ175ml

V₁=(2.2ₓ175ml)/8.8

=43.75 ml
