The structure the arrow is pointing to is the nucleus and it helps store genetic material (DNA) in living cells.

<h3>What is an organelle?</h3>

Organelle is a specialized structure found inside cells that carries out a specific life process. examples are ribosomes, vacuoles, nucleus etc.

The nucleus is the large membrane-enclosed organelle found in eukaryotic cells which contains genetic material.

The nucleus is located at the center of living cells and it functions to store genetic material called DNA. The DNA is transferred to offsprings for inheritance of traits.

According to this question, a microscopic image of a cell is shown. The arrow pointed to the nucleus of the cell.

Answer:

nucleic acid

Explanation:

ATP -

In the living organisms it is a very important source of energy for various biological processes like chemical synthesis , nerve impulse propagation and contraction of muscles , is referred to as Adenosine triphosphate ( ATP ) .

ATP is a nucleic acid , which is a single chain nucleotide , which is composed of ribose sugar along with three phosphate groups .

ATP is also known as the battery of the cell.

Hence , from the given information of the question ,

The correct term is nucleic acid.

Calculate the standard reaction enthalpy for the reaction NO2(g) → NO(g) + O(g) given +142.7 kJ/mol for the standard enthalpy of

bulgar [2K]

Answer:

The standard reaction enthalpy for the given reaction is 235.15 kJ/mol.

Explanation:

$O_2(g) \rightarrow \frac{2}{3}O_3(g),\Delta H^o_{1}=142.7 kJ/mol$ ..[1]

$O_2(g) \rightarrow 2 O(g),\Delta H^o_{2}=498.4 kJ/mol$ ..[2]

$NO(g) + O_3(g)\rightarrow NO_2(g) + O_2(g) ,\Delta H^o_{3} = -200 kJ/mol$ ..[3]

$NO_2(g)\rightarrow NO(g) + O(g),\Delta H^o_{4}=?$ ..[4]

Using Hess's law:

Hess’s law of constant heat summation states that the amount of heat absorbed or evolved in a given chemical equation remains the same whether the process occurs in one step or several steps.

2 × [4] = [2]- (3 ) × [1] - (2) × [3]

$2\times \Delta H^o_{4}=\Delta H^o_{2} -3\times \Delta H^o_{1}-2\times \Delta H^o_{3}$

$2\times \Delta H^o_{4}=498.4 kJ/mol-3\times 142.7 kJ/mol-2\times -200 kJ/mol$

$2\times \Delta H^o_{4}=470.3 kJ/mol$

$\Delta H^o_{4}=\frac{470.3 kJ/mol}{2}=235.15 kJ/mol$

The standard reaction enthalpy for the given reaction is 235.15 kJ/mol.

Why are ions charged particles?

Deffense [45]

Answer:

An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
