The gas hydrogen occurs as diatomic molecules and zinc chloride has the formula ZnCl2.
Zn + 2HCl ==> H2 + Zn Cl2
the correct answers are:
1) The electron affinities of the elements in Group 17 are larger (more negative) than the elements in Group 1.
3) Elements in Group 14 have larger (more negative) electron affinities than elements in Group 15.

The pH of human blood ranges from 7.35 to 7.45 with it usually being around 7.40. If the blood pH gets below 7.35 a person goes into acidosis. If the pH gets above 7.45 a person goes into alkalosis. Both acidosis and alkalosis can be fatal. How much more acidic is a person’s blood if it has a pH of 7.3 compared to its preferred 7.4? How much more alkaline is a person’s blood if it has a pH of 7.6 rather than its preferred 7.4?
the one that is wrong is a. increase the molecular weight of the gas , the molecular weight never changes when a solid turns to a liquid or when a liquid turns to a gas .
