Answer:
Answer: 882mmHg
Explanation:
In a closed-end manometer, the gas added is under a pressure that is measured against atmospheric pressure. The difference in pressure between both gases is equal to the difference in mercury levels. Thus, the pressure of the argon can be:
783 mmHg - 96.0mmHg = 687mmHg
783 mmHg - 96.0mmHg = 879mmHg
Based on the options, the possible answer (The nearest to the second value) is:
<h3>Answer: 882mmHg</h3>
Nice written.
Is it written by you yourself or you have copied it from somewhere?
It depends if you are talking about the ones that go up or down
or left and right
the ones that go up and down are called groups
the onesthat go left and right are periods
Answer:
E. 8.08 x 10⁴.
Explanation:
Hello,
In this case, for the reaction:

We can compute the Gibbs free energy of reaction via:

Since both the entropy and enthalpy of reaction are given at 298 K (standard temperature), therefore:

Then, as the equilibrium constant is computed as:

We obtain:

For which the answer is E. 8.08 x 10⁴.
