Answer: Igneous

Explanation: Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.

A sample of a gas has a volume if 852mL at 288K. What temperature did s necessary for the gas to have a volume of 945mL?
asambeis [7]

Answer:

The answer to your question is T2 = 319.4°K  

Explanation:

Data

Volume 1 = V1 = 852 ml

Temperature 1 = T1 = 288°K

Volume 2 = V2 = 945 ml

Temperature 2 = T2 = ?

Process

To solve this problem, use Charles' law.

            V1/T1 = V2/T2

-Solve for T2

            T2 = V2T1/V1

-Substitution

            T2 = (945 x 288) / 852

-Simplification

            T2 = 272160 / 852

-Result

            T2 = 319.4°K

The reaction converting glycerol to glycerol-3-phosphate (energetically unfavorable) can be coupled with the conversion of ATP t
Brut [27]

Answer:

glycerol-3-phosphate, ADP, H⁺

Explanation:

The reaction of converting glycerol to glycerol-3-phosphate which makes is unfavorable and is coupled with the second reaction which involves conversion of ATP to ADP which is high energetically favorable.

Reaction 1:  Glycerol + HPO₄²⁻ ⇒ Glycerol-3-phosphate + water

Reaction 2:             ATP  + H₂O ⇒ ADP + HPO₄²⁻ + H⁺

The coupled reaction of both the reactions become favorable. Thus, the overall coupled reaction is:

<u>Glycerol + ATP ⇒ Glycerol-3-phosphate + ADP + H⁺</u>

The net products are = glycerol-3-phosphate, ADP, H⁺
