Coal a is a chemical compound. It is pure carbon. You cannot separate carbon into other molecules without changing its chemical consitution.

Petroleum is a mixture of many chemical compounds, hydrocarbons, plus other elements. Petroleum components contain carbon, hydrogen, oxygen, nitrogen, sulfur, and some metal traces. The different compounds that consitute the petroleum can be separated by physical media like distillation.

natita [175]

Answer:

The correct option is C (Uncompetitive inhibitor)

Explanation:

  • Uncompetitive inhibitor takes place when an inhibitor binds at different site (allosteric site) of the enzyme after the substrate forms a complex with the enzyme.
  • The Uncompetitive inhibitors bind to a different site on the enzyme while the substrate binds to the active site on the enzyme.
  • It differs from non-competitive inhibition because non-competitive inhibition can occur with or without the presence of the substrate.
  • Uncompetitive inhibition is also referred to as Anti-competitive inhibition.

At what temperature will a fixed amount of gas with a volumeof
svetlana [45]

Answer:

260K

Explanation:

We use the general gas equation to solve this. The mathematical form can be represented as follows:

P1V1/T1 = P2V2/T2

We are to look for T2 from the question, rearranging the equation yields:

T2 = T1P2V2/P1V1

So what information do we have from the question:

T2= ?

P2 = 640mmHg

V2 = 198L

P1 = 760mmHg

T1 = 273K as they gas is at S.T.P since pressure is 760mmHg which is the standard pressure

V1 = 175L

We now substitute all these values:

T2 = (273 * 640 * 198)/(760 * 175)

T2 = 260K
