When 2.50 mol of mg3n2 are allowed to react how many moles of h2o also react?

1 answer:

7 0

Notice that in the equation given, there is 1 mol of Mg3N2 and 6 mol of H2O. Consequently, the question is requesting, if we took 2.5 mol of Mg3N2, how many mol of H2O would be essential to complete a similar reaction -- in quintessence, multiplying everything by 2.5:

the solution would be: 6 * 2.5 = 15 mol

The side chain of histidine has a pKa of about 6. What percent of histidine side chains would be deprotonated at pH 7.5

Setler [38]

The percent of histidine side chains would be deprotonated at pH 7.5 is 5.77 %.

The term pKa refers to the negative logarithm of the acid dissociation constant (Ka). The pH is the negative logarithm of the hydrogen ion concentration.

Hence;

Ka = Antilog (-6) = $1 * 10^-6$

[H^+] = Antilog (-7.5) = $3 * 10^-8 M$

We now have to use the formula;

α = $\sqrt{} \frac{Ka}{[H^+] }$

α = $\sqrt{} \frac{ 1 *10^-6}{3 *10^-8 }$

α = 5.77 %

Hence, the percent of histidine side chains would be deprotonated at pH 7.5 is 5.77 %.

Which of the following is the correct definition of radiant energy?

torisob [31]

Answer:

energy that is transmitted in the form of electromagnetic waves.

Explanation:

Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum.
