Plssss help me!!!!!!!

Using the formula M1V1 = M2V2 , how many milliliters of a 2. 50 M hydrochloric acid solution is required to make 100. 0 mL of a

gladu [14]

Dilution of the solution can be calculated by the formula of the molarity and volume. The initial volume of 2.50 M solution was 30 mL.

<h3>What is the relationship between molar concentration and dilution?</h3>

Molar concentration or the dilution factor is in an inverse relationship and with an increase in the dilution, the molarity of the solution decreases.

Given,

Initial molarity = 2.50 M

initial volume = ?

Final molarity = 0.750 M

Final volume = 100.0 ml

Substituting values in the formula:

$\begin{aligned}\rm V_{1} &= \rm \dfrac{M_{2}V_{2}}{M_{1}}\\\\&= \dfrac{0.750 \times 100}{2.50}\\\\&= 30 \;\rm mL\end{aligned}$

Therefore, 30 mL was the initial volume of the solution before it was diluted.

The sun shines with equal intensity on a farm field, an asphalt road, and the ocean. Which material will heat up most during the

Stolb23 [73]

Answer:

The sun shines with equal intensity on a farm field, an asphalt road and the ocean. So basically asphalt road are heated the most during the day

Explanation:

The heat of water is more than the specific heat of sand.

Therefore sand is hot.

.Water is reflecting solar radiation.

The land retains more heat since the land absorb solar radiation.

Therefore the land surfaces warm faster.

Since water is a slow conductor of heat, it need more energy than the sand. so its temperature is increasing. soil loses heat faster.

The ocean heats slower than land , the land air is more warmer than lean air. After the sun set the land loses heat quickly .The air above it cools.

What is true about all plutons? They form near Earth’s surface. They form below Earth’s surface. They cut across other rock laye

pishuonlain [190]

Answer: The correct answer is that they are formed below Earth's surface.

Explanation:

Plutons are defined as the intrusive igneous rocks named as plutonic rocks which are formed when the magma gets cools down slowly and solidifies below the Earth's surface.

It is different from volcanic rocks which are formed when lava gets cools down and solidifies on the Earth's surface.

Hence, the correct answer is that they are formed below Earth's surface.
