All nickel atoms would have the same number of protons or atomic number.
Some of the solutions exhibit colligative properties. These properties depend on the amount of
solute dissolved in a solvent. These properties include freezing point depression, boiling
point elevation, osmotic pressure and vapor pressure lowering. From the given choices, the correct answer is the first option. Pure water will have the lowest boiling point because there are no solute particles to change the boiling point of water while other options will have an elevated boiling point because of the solute.

Explanation:
According to the given data, the turnover number can be calculated as follows.
Turnover number =
Therefore, moles of hydrolyzed is as follows.
Moles of hydrolyzed =
=
= 0.00682 moles
Now, moles of hydolyzed per second is calculated as follows.
Moles of hydolyzed per second =
=
And,
Moles of enzyme =
=
= moles
Therefore, the value of is as follows.
= per second
= per minute
= per minute
Thus, we can conclude that the turnover number () of carbonic anhydrase (in units of ) is per minute.
Answer : The heat of combustion of n-propanol is 0.554 kJ/mol
Explanation :
First we have to calculate the moles of n-propanol.
Molar mass of n-propanol = 60.09 g/mole
Now we have to calculate the heat of combustion of n-propanol.
As, 0.0166 mole of n-propanol liberated heat of combustion = -33.4 kJ
So, 1 mole of n-propanol liberated heat of combustion = 0.0166 × (-33.4 kJ)
= 0.554 kJ/mol
Therefore, the heat of combustion of n-propanol is 0.554 kJ/mol
From the choices presented above, I can say the correct answer is option D. The reaction that falls under the formation reaction type is <span>6C(graphite) + 6H2O(s) → C6H12O6(s). This is because the reactants combine and form only one single large product.</span>
