Answer: B

Explanation: Wave energy is a renewable energy whereby we capture the energy that is being generated naturally by waves. Waves get their energy from the wind passing over the surface of the sea as well and can transmit their energy over long distances with little degradation; wave energy is considered a significant renewable energy resource.

What is the most soluble salt of the following set? What is the most soluble salt of the following set?

DiKsa [7]

Answer:

Explanation:

The solubility product of a solid is the amount of solid dissociates into its respective ions in the solution. Thus more the value of the Ksp, the more is the salt soluble in the solvent.

So, Given that:-

$Sn(OH)_2\ (K_{sp} =1.6\times 10^{-19})$

$Al(OH)_3\ (K_{sp} =1.9\times 10^{-33})$

$AgCN\ (K_{sp} =6.0\times 10^{-17})$

$Fe(OH)_3\ (K_{sp} =2.6\times 10^{-39})$

The salt having highest value of Ksp is AgCN. So, it is most soluble.

. percent iron in a mixture that is 52.2% Fe2O3

AVprozaik [17]

Answer:

36.51%.

Explanation:

First find the percentage of iron in pure Fe2O3 using the atomic masses of the elements:

= (2 * 55.845) * 100 / (2*55.845+ 3*15.999)

= 69.94 %.

So the percentage of iron in the mixture

= 52.2 * 0.6994

= 36.51 (answer).
