The answer to your question is true.
If I remember correctly, it's some natural gas that contains methane..hope they don't need the full name. It's somewhere online im sure

Answer:</h3>
40 atm
<h3>
Explanation:</h3>
- According to Boyle's law, the pressure and the volume of a fixed mass of a gas are inversely proportional at constant absolute temperature.
- That is;
- At varying pressure and volume,
P1V1 =P2V2
In this case,
Initial volume, V1 = 2 L
Initial pressure, P1 = 1 atm
New volume, V2 = 0.05 L
We are required to calculate the new pressure,
Rearranging the formula;
P2 = P1V1 ÷ V2
= (1 atm × 2L) ÷ 0.05 L
= 40 atm
Therefore, the pressure required is 40 atm
Answer:
No. of protons = 34
Explanation:
First we need to calculate the number of electrons in one mole of the the element:
No. of electrons per mole = Total Mass of Electrons/Mass of 1 Electron
No. of electrons per mole = (18.65 x 10⁻³ g)/(9.109 x 10⁻²⁸ g)
No. of electrons per mole = 2.04 x 10²⁵ electrons/mol
Now, we calculate the no. of electrons in 1 atom:
No. of electrons per atom = No. of Electrons per mole/No. of atoms per mole
No. of electrons per atom = (2.04 x 10²⁵ electrons/mol)/(6.022 x 10²³ atoms/mol)
No. of electrons per atom = 34 electrons/atom
Since, the no. of protons in a pure element are equal to the number of electrons. Therefore,
<u>No. of protons = 34</u>
