When we wish to convert a gas to liquid we have to either

a) decrease temperature

b) increase pressure

In case of fire extinguisher the CO2 is found to be in liquid state, this is as the CO2 is pressurized at high pressure which keeps CO2 in liquid state

the ideal pressure and temperature conditions when CO2 gas can be converted to CO2 gas

Pressure = 5 - 73 atm

Temperature = -57  to 31 degree Celsius

URGENT!!!What volume of a 0.88 M solution can be made using 130. Grams of FeCI^2?
Likurg_2 [28]

Answer:

1.16L can be made

Explanation:

Molarity = Mol / Volume

Volume = Mol / Molarity

Let's determine the moles of salt, with that mass:

130 g FeCl₂ . 1mol / 126.75 g = 1.02 moles of FeCl₂

Volume = 1.02 mol / 0.88 mol/L → 1.16L

To cook food, a microwave oven converts electrical energy into ________ energy. A) electromagnetic B) heat C) mechanical D) nucl
Mariana [72]

Answer: Option (B) is the correct answer.

Explanation:

When we heat food in a microwave then the electrical energy of microwave produces microwaves which are also part of electromagnetic spectrum.

These microwaves are absorbed by food and as a result microwaves change into heat energy. Therefore, food becomes hot.

Thus, we can conclude that to cook food, a microwave oven converts electrical energy into heat energy.

PLEASE HELP ME Which of the following is an example of -ΔS? Picking up marbles and placing them in a sack Paint spilling onto th
yan [13]

Answer:

Picking up marbles and placing them in a sack

Explanation:

The entropy of a chemical system is defined as the measure of disorder. Therefore a negative change in entropy is the movement to a more ordered state. The only option here which achieves a more ordered state, would be the first option.

Picking up marbles and placing them in a stack achieves more order, rather than the other options - that achieve more disorder.
