provide energy for cellular work
B)
produce heat energy
C)
reduce the activation energy of a reaction
D)
take energy from cellular work
Answer:
A) provide energy for cellular work
Explanation:
The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the "molecular currency" of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids.
ATP always GIVES ENERGY
The primary function of ATP is to provide energy for cellular work. It does so by transferring a phosphate group to a molecule and forming ADP. This key process drives cellular metabolism and enables life-critical activities.
The key role of ATP, also known as Adenosine Triphosphate, is to provide energy for cellular work. ATP carries out this function by transferring a phosphate group to a molecule. This breaks a high energy bond and forms ADP (Adenosine Diphosphate), releasing energy that can be utilized by the cell to do work.
ATP acts as the primary energy currency of the cell. This process is at the heart of cellular metabolism and is common to all living organisms. Essentially, ATP acts as a bridge, transferring energy from chemical reactions that yield energy to cellular processes that consume energy, such as muscular contraction, cell division, or the synthesis of biomolecules.

The substance that represents a compound among the given options is CO. The correct answer is (3) CO(g)
From the question,
We are to determine which of the given substances is a compound.
First, we will define a compound
A compound is a chemical species that is formed when two or more atoms join together chemically, with covalent or ionic bonds.
OR
A compound is a substance that contains atoms of two or more different elements, and these atoms are chemically joined together
NOTE: A molecule consisting of atoms of only one element is NOT a compound.
Among the given options, only CO satisfies the definition of a compound, because it contains two different elements, Carbon (C) and Oxygen (O).
Hence, the substance that represents a compound among the given options is CO. The correct answer is (3) CO(g)

Explanation:
I checked the periodic table hope I helped
The final concentration of the solution prepared by diluting 35.0 ml of 12.0 M HCl to a final volume of 1.20 L is 0.35 M.
The final concentration of a solution prepared by diluting 35.0 ml of 12.0 M HCl to a final volume of 1.20 L can be calculated using the formula for dilution: M1V1 = M2V2. In this formula, M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.
Firstly, we convert the initial volume from ml to litres because the final volume is given in litres. So, 35.0 ml = 0.035 L. Therefore, the equation becomes: 12.0 M * 0.035 L = M2 * 1.20 L.
On rearranging the equation to solve for M2, the result is 0.35 M.

The pH of the solution created is 7.21
Explanation:
Ka1 = 6.9 X 10⁻³
Ka2 = 6.2 X 10⁻⁸
Ka3 = 4.8 X 10⁻¹³
pKa = - log( Ka)
Thus,
pKa1 = - log ( 6.9 X 10⁻³) = 2.16
pKa2 = - log ( 6.2 X 10⁻⁸ ) = 7.21
pKa3 = - log ( 4.8 X 10⁻¹³ ) = 12.3
KH₂PO₄ + Na₂HPO₄ = KH₃PO₄ + Na₂PO₄
Ka2 = [ KH₃PO₄] [Na₂PO₄] / [KH₂PO₄] [Na₂HPO₄]
log (Ka2 ) = log [[ KH₃PO₄] [Na₂PO₄] / [KH₂PO₄] [Na₂HPO₄]]
pH = pKa2 + log [KH₂PO₄] /[Na₂HPO₄] = 7.21
Therefore, the pH of the solution created is 7.21
