As refrigerant passes through the expansion valve, it cools down or heats up?

Chemistry

Answer:

It cools down

Explanation:

The expansion valve lowers down the pressure of the refrigerant (in liquid form). This allows the refrigerant to expand. As the refrigerant expands the heated molecules in it get spread to a larger area and thus the oscillatory vibrations in the molecules get reduced there by reducing the kinetic energy ( KE )and thus the heat. Also sometimes spray of Aerosols are used to cool down the refrigerant.

Explain how it is possible for 10 grams of methane fuel to burn and emit 27 grams of carbon dioxide. Discuss whether or not this
Rufina [12.5K]

This reaction obeys the law of conservation of mass.

Explanation:

In the burning reaction, methane (CH₄) react with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O):

CH₄ + 2 O₂ → CO₂ + 2 H₂O

Now we calculate the number of moles of methane and carbon dioxide:

number of moles = mass / molar weight

number of moles of methane = 10 / 16.04 = 0.62 moles

number of moles of carbon dioxide = 27 / 44.01 = 0.61 moles

From the chemical reaction we see that 1 mole of methane produces 1 moles of carbon dioxide so 0.6 moles of methane produces 0.6 mole of carbon dioxide. This reaction obeys the law of conservation of mass because the mass of reactants is equal to the mass of products.

The number of particles in one mole of a chemical substances is 602,200,000,000,000,000,000,000 particles. What is the correct w
crimeas [40]

The correct way to write this number in scientific notation : 6.022 x 10²³

<h3>Further explanation </h3>

Scientific Notation is a standard form of writing numbers used in mathematical operations

The rules:

1. Writing order : first digit, decimal point, next digit

2. Then followed by powers of 10 (the value can be +/-)

If the value is> 10 (the power of 10 is +), the decimal point is moved to the left, to the right of the first digit

If the value is <10 ((the power of 10 is -), the decimal point is moved to the right, to the right of the first digit

I certainly didn't count the details of the number of zeros listed, but only saw the answer choices.

And the right ones are: 6.022 x 10²³
