fiasKO [112]

Answer:

used to complete the glicolisis process

Explanation:

A glucose molecule will generate the necessary energy to the body to compete their own metabolic processes.

At the begging of the process, the glucose change into 2 molecules of gliceraldehyde 3 - phosphate. In this first process the glucose molecule consume 2 molecules of ATP (the energetic molecule).

After this first process, the aldehyde turns into piruvate, during this process, there is produced 2 molecules of ATP, so it is producing chemical energy.

If during this process the cell need to enter into another metabolic process (pentose ways) then the gain of ATP deplets.

A chemist wants to calculate the amount of heat that is absorbed by a sample of copper as it is melted. Which constant should sh
34kurt

The constant used for the absorption of heat by the sample in melting is +\Delta H_{fus}.  Thus, option A is correct.

The chemical reaction has been defined as the energy in which the energy has been released or absorbed for the breaking of bonds in the reactants and the formation of product.

<h3>Constant for energy absorbed</h3>

The energy has been absorbed in the melting of the copper sample. Thus, the sample has been converted from the solid to the liquid state.

The change in energy with the conversion in solid and liquid state has been termed as heat of fusion.

The energy has been absorbed by the system, thus it has been marked with the positive sign.

Therefore, +\Delta H_{fus} has been the constant used for the absorption of heat by the sample in melting. Thus, option A is correct.

Which equation represents the combined gas law?
stealth61 [152]

Answer:

P1V1/T1= P2V2/T2

Explanation:

Combined gas law involves Boyle's law and Charles law altogether with the formula of Boyle's law as P1V1=P2V2

formula for charles law as V1/T1=V2/T2

so when combined form P1V1/T1=P2V2/T2
