Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease

Increases.

Explanation:

The pH of the intermembrane space increases as the poisoning of cyanide occurs. After cyanide poisoning, the electron transport chain can stop pumping of electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would also decreases, and ATP synthesis would stop to occur. The pH of the intermembrane space is neutral i.e. 7 but due to cyanide it move towards basic.

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
