25 yard [3 feet / 1 yard] [12 inches / 1 foot] = 25 * 3 * 12 = 900 inches in 25 yards.

Always put the unit you are going to on top and the unit you are coming from on the bottom.

So in this example, you want to going to feet to start with. That's on top. Yards are on the bottom of the first bracket.  In second bracket feet are on the bottom, inches are what you are going to on the top.

Answer:

[tex]\boxed {\boxed {\sf B. \ 0.5 \ M}}[/tex]

Explanation:

Molarity is a measure of concentration in moles per liter. The formula for calculating molarity is:

[tex]molarity= \frac{moles \ of \ solute}{ liters \ of \ solution}[/tex]

There are 2 moles of a compound or the solute. There are 4 liters of water or the solution.

Substitute the values into the formula.

[tex]molarity = \frac{ 2 \ mol}{ 4 \ L}[/tex]

Divide.

[tex]molarity= 0.5 \ mol /L[/tex]

1 mole per liter is equal to 1 Molar, so the solution's molarity of 0.5 mol/L is equal to 0.5 M.

[tex]molarity = 0.5 \ M[/tex]

The molarity of the solution is 0.5 Molar and choice B is correct.

Answer:

I think option(D) is more appropriate but not sure.

The correct statement of what occurs at a turbine during electricity production is they are turned using steam. The correct option is D.

A turbine is a fan-like structure that runs by hydro or air power that generates electricity. Turbines that produce electricity are huge structures made of iron or heavy metal.

Electricity is a form of energy that converts thermal energy into electrical energy, which leads to burning the light or running fans and other machines. It is an important form of energy because all machines and power run by electricity.

Turbines run by using steam. They convert steam or fluid or air into mechanical energy. The water run over the turbines and when turbines move it produces electricity and energy.

Thus, the correct option is D. They are turned using steam.
