Answer: (1). If calcium bromide is dissolved in water you can say that the equilibrium concentrations of calcium and bromide ions are high.

(2). The solubility of calcium bromide in water is high.

Explanation:

We know that for a reaction its solubility product is equal to the product of concentration of ions present.

For example, CaBr_{2} \rightarrow Ca^{2+} + 2Br^{-}

      K_{sp} = [Ca^{2+}][Br^{-}]^{2}

As it is given that for this reaction K_{sp} > 1. Hence, the product of concentration of both these ions will be greater than 1 which means that products are favored.

Therefore, equilibrium concentrations of calcium and bromide ions are high.

Also, more is the number of these ions formed more will be the solubility of the compound (CaBr_{2}).

As a result, the solubility of calcium bromide in water is high.

A sample of argon gas has a volume of 73 mL at a pressure of 1.20 atm and a temperature of 112 degrees Celsius. What is the fina
NeX [460]

Answer:

V₂ → 106.6 mL

Explanation:

We apply the Ideal Gases Law to solve the problem. For the two situations:

P . V = n . R . T

Moles are still the same so → P. V / R. T = n

As R is a constant, the formula to solve this is: P . V / T

P₁ . V₁ / T₁ = P₂ .V₂ / T₂   Let's replace data:

(1.20 atm . 73mL) / 112°C = (0.55 atm . V₂) / 75°C

((87.6 mL.atm) / 112°C) . 75°C = 0.55 atm . V₂

58.66 mL.atm = 0.55 atm . V₂

58.66 mL.atm / 0.55 atm = V₂ → 106.6 mL

How do different types of waves make particles of matter move
Alborosie

That depends on the wave, if you're talking about sound, it makes matter move in a similar wavelength as them, a mountainous shape. Light however would make whatever matter it hits start to move in the same direction as the light's angle of approach.
