Given reaction represents dissociation of bromine gas to form bromine atoms
Br2(g) ↔ 2Br(g)
The enthalpy of the above reaction is given as:
ΔH = ∑n(products)Δ
- ∑n(reactants)Δ
where n = number of moles
Δ
= enthalpy of formation
ΔH = [2*ΔH(Br(g)) - ΔH(Br2(g))] = 2*111.9 - 30.9 = 192.9 kJ/mol
Thus, enthalpy of dissociation is the bond energy of Br-Br = 192.9 kJ/mol
Answer:
Amino acids, along with glucose, are reabsorbed in the glomerular system with a passive or active mechanism as the fluid travels through the entire renal tubular system and enters the circulation again.
Active mechanisms are those that require expenditure of energy, that is, expenditure of the energy currency, while the passive ones do not, they occur through spontaneous non-energy processes such as osmosis, the osmotic gradient and the difference in concentrations in different compartments.
Explanation:
Glomerular filtration is the regulator of the excretion of metabolites and toxic molecules or not necessary for our body. That is why if the amino acid values are high as well as those of glucose in urine, we will be facing a pathology.
If glucose is increased, it is because there is a glycemic peak in blood volume, hence possible diabetes.
And if the amino acids are increased, we could be facing an autoimmune or proteolytic pathology where a large amount of body proteins such as muscle proteins would be breaking down and releasing the amino acids that make it up, this phenomenon usually appears in those people who suffer from rhabdomyolysis in expenses very intense energy sources not appropriate.
On the other hand, glomerular filtration occurs in the kidney and is carried out by the nephron, which is the functional unit of the kidney, within it there is a specific tubular system in collection, absorption and reabsorption, added to the presence of Bowman's capsule.
Explanation:
Molecules of compounds are are compounds composed two or more than two different elements.
Molecules of an elements are made up two or more than two numbers of same type of atoms
(a) 
It is compound composed of sulfur and oxygen element.
(b) 
It is a molecules of a single element made up of 8 sulfur atoms.
(c) Cs
It is a symbol of an element named cesium.
(d) 
It is compound composed of nitrogen and oxygen element.
(e) O
It is a symbol of an element named oxygen.
(f)
It is a molecule of a single element made up of 2 oxygen atoms.
(g) 
It is a molecule of a single element made up of 3 oxygen atoms.
(h)
It is compound composed of carbon and hydrogen element.
(i) KBr
It is compound composed of potassium and bromine element.
(j) S
It is a symbol of an element named sulfur.
(k) 
It is a molecule of a single element made up of 4 phosphorus atoms.
(l) LiF

M1V1 = M2V2
(2.50)(100.0) = (0.550)V2
V2 = 455mL
You can make 455mL of 0.550M solution from 100.0mL of 2.50M solution.
Answer:
I believe it's false because the atomic number is the number of protons in the nucleus of an atom.
