The concentration of the solid phase _____ the quantity present.

2 answers:

5 0

The concentration of the solid phase always remains the same regardless of the quantity present. Most of the chemical reactions and separation systems involve the transport of more or one components in solid phase.
For example, in the process of solid catalyzed reactions, the result of solid phase transport might be negligible though it is hard to identify it in the rate of data in the analysis.

Answer: Option (b) is the correct answer.

Explanation:

A solution that contains more number of solute particles than the solvent particles is known as a concentrated solution.

For example, concentrated solution of sulfuric acid.

On the other hand, a solution that contains less number of solute particles than the solvent particles is known as a dilute solution.

For example, a dilute solution of HCl.

Hence, we can conclude that concentration of a substance changes with change in the amount of solute.

Therefore, the concentration of the solid phase changes with the amount of the quantity present.

An object with the mass of 2300 g has a force of 6.2 Newton's applied to it. What is the resulting acceleration of the object?

Triss [41]

Answer:

$\boxed {\boxed {\sf a\approx 2.7 \ m/s^2}}$

Explanation:

Force is equal to mass times acceleration.

$F=m*a$

By dividing both sides by m, we rearrange the formula for a (acceleration).

$\frac{F}{m} =a$

The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.

A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².

The mass is 2300 grams, but we need to convert it to kilograms.

To convert grams to kilograms, divide by 1,000
2300 g/1000= 2.3 kg

$F= 6.2 \ kg*m/s^2\\m=2.3 \ kg$

Substitute the values into the formula.

$a=\frac{6.2 \ kg*m/s^2}{2.3 \ kg}$

Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).

$a=\frac{6.2 \ m/s^2}{2.3 \ }$

$a=2.69565217 \ m/s^2$

Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7

$a\approx 2.7 \ m/s^2$

The acceleration is about <u>2.7 meters per second squared.</u>

Answer: Elevation

Explanation:

The altitude of a feature of the earth's surface is usually called its elevation, vertical distance from a datum plane, usually mean sea level to a point above the earth. Often used synonymously with altitude, elevation is the height on the earth's surface and altitude, the height in space above the surface.
