A Gas OCCUPIES 525ML AT A PRESSURE OF 85.0 kPa WHAT WOULD THE VOLUME OF THE GAS BE AT THE PRESSURE OF 65.0 kPa
german

Boyle's law of ideal gas: This law states that the volume of a gas is inversely proportional to its pressure at a constant temperature. Acc to this law we can write the relation of pressure and volume as:

PV=Constant

That means:

P_{1}V_{1}=P_{2}V_{2}

From that equation we can calculate Volume of gas at a certain pressure:

P₁=Initial pressure

V₁=Initial volume

P₂=Final pressure

V₂= Final volume

Here P₁, initial pressure is given as 85.0 kPa

V₁, initial volume is given as 525 mL

P₂, final pressure is 65.0 kPa

P_{1}V_{1}=P_{2}V_{2}

so,

V_{2}=85\times 525\div 65

=686 mL

Volume of gas will be 686 mL.

Which group of archaea are chemoautotrophic anaerobes that use hydrogen as an electron donor and sulfur compounds as terminal el
vodomira [7]

The group of archaea that are chemoautotrophic anaerobes that use hydrogen as an electron donor and sulfur compounds as terminal electron acceptors are the

Thermoacidophiles.

<h3>What are chemoautotrophic anaerobes?</h3>

The chemoautotrophic anaerobes are those organisms that derive energy for survival through the reduction of the following compounds:

  • CO2 to CH4, or

  • SO4 to H2S.

Thermoacidophiles is a typical example of the group of archaea that are chemoautotrophic anaerobes that use hydrogen as an electron donor and sulfur compounds as terminal electron acceptors.
