The new volume of a sample of gas initially occupying a 500 mL container at a pressure of 1.4 atm and a temperature of 25 °C is 281.01mL.

<h3>How to calculate volume?</h3>

The volume of a gas can be calculated using the following formula:

P1V1//T1 = P2V2/T2

Where;

  • P1 = initial pressure
  • P2 = final pressure
  • V1 = initial volume
  • V2 = final volume
  • T1 = initial temperature
  • T2 = final temperature

1.4 × 500/298 = 2.7 × V2/323

2.348 × 323 = 2.7V2

758.72 = 2.7V2

V2 = 281.009mL

Therefore, the new volume of a sample of gas initially occupying a 500 mL container at a pressure of 1.4 atm and a temperature of 25 °C is 281.01mL.

Would you classify hydrogen as a metal or a non-metal? <br>Explain why.​
Igoryamba

Answer:

HYDROGEN IS A NON METAL.

HYDROGEN IS A GAS ELEMENT

Hydrogen is nonmetallic, except at extremely high pressures, and readily forms a single covalent bond with most nonmetallic elements, forming compounds such as water and nearly all organic compounds.

Draw the Lewis structure for methane (CH4) and ethane (C2H6) in the box below. Then predict which would have the higher boiling
Alinara [238K]

Answer:

Ethane would have a higher boiling point.

Explanation:

In this case, for the lewis structures, we have to keep in mind that all atoms must have <u>8 electrons</u> (except hydrogen). Additionally, each carbon would have <u>4 valence electrons</u>, with this in mind, for methane we have to put the hydrogens around the carbon, and with this structure, we will have 8 electrons for the carbon. In ethane, we will have a bond between the carbons, therefore we have to put three hydrogens around each carbon to obtain 8 electrons for each carbon.

Now, the main difference between methane and ethane is an <u>additional carbon</u>. In ethane, we have an additional carbon, therefore due to this additional carbon, we will have <u>more area of interaction</u> for ethane. If we have more area of interaction we have to give <u>more energy</u> to the molecule to convert from liquid to gas, so, the ethane will have a higher boiling point.

I hope it helps!
