Answer:
Isotopes of an element share the same number of protons but have different numbers of neutrons. Let's use carbon as an example. There are three isotopes of carbon found in nature – carbon-12, carbon-13, and carbon-14. All three have six protons, but their neutron numbers - 6, 7, and 8, respectively - all differ.
Explanation:
When we replace neutral ligands with negative ligands then the value of C.Δ will decrease.
In coordination chemistry, a ligand is an ion or molecule that binds to a significant steel atom to shape coordination complicated. The bonding with the metal generally includes a formal donation of 1 or more of the ligand's electron pairs regularly through Lewis Bases.
A ligand is defined as any molecule or atom that irreversibly binds to a receiving protein molecule, otherwise known as a receptor. whilst a ligand binds to its respective receptor, the shape and/or interest of the ligand is altered to provoke several special styles of cellular responses.

The net charge on the structure as shown in the question is -1.
<h3>What is a charged specie?</h3>
We say that a specie is charged if the specie has an excess of positive or negative charge. An excess of the positive charge means that the substance is positively charged while an excess if the negative charge simply means that the object is negative charged.
When we have a chemical structure as we have seen, it is possible that the structure as we have it could have a net charge. The net charge that the structure has can be deduced by looking at the formal charges that are carried by all the atoms that we have in the system.
The charge as we can see that is on the central atom of the molecule is the -1 charge hence this is the charge that is carried overall by the molecule.
If we then look at the structure as we can see, we can see that there is a charge of negative one that is attached to the atom of chlorine as is clearly visible and obvious from the image attached to the question.

Answer:
26.8 °C
Explanation:
Step 1: Given and required data
- Energy transferred to the water (Q): 2100 J
- Initial temperature of the water (T₂): 23.6 °C
- Final temperature of the water (T₁): ?
- Specific heat of water (c): 4.184 J/g.°C
Step 2: Calculate the final temperature of the water
We will use the following expression.
Q = c × m × (T₂ - T₁)
T₂ = 2100 J/(4.184 J/g.°C) × 155 g + 23.6 °C = 26.8 °C
The most common isotope of hydrogen is H¹ and this isotope has 0 neutrons
