If 10.0 liters of h2(g) at STP is heated to a temperature of 546 K, pressure remaining constant, the new volume of the gas will be

Answers

Answer 1

Answer:

20L

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 10L

Initial Temperature (T1) = stp = 273K

Final temperature (T2) = 546K

Final volume (V2) =..?

The new volume of the gas can be obtained by using the Charles' law equation as shown below:

V1/T1 = V2/T2

10/273 = V2/546

Cross multiply to express in linear form

273 x V2 = 10 x 546

Divide both side by 273

V2 = (10 x 546) / 273

V2 = 20L

Therefore, the new volume of the gas is 20L.

What types of elements- metals,nonmetals, or metalloids require
the most energy to remove an
electron?
Why do these elements have a higher ionization energy?

Answers

Answer:

Noble gases

Explanation:

The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.

The reason for this difficult is that their electronic configuration confers a stable configuration them.

The ionization energy is the energy required to remove the most loosely held electrons in an atom.
Due to the special stability of noble gases, it is very difficult to remove electrons from an atom of noble gases.

Which list of the phases of H2O is arranged in order of increasing entropy?(1) ice, steam, and liquid water
(2) ice, liquid water, and steam
(3) steam, liquid water, and ice
(4) steam, ice, and liquid water

Answers

The answer is (2). The entropy is measured the disorder degree. So the increasing of entropy of the phases are solid, liquid and gas. So the answer is ice, liquid water and steam.
