Which nonmetal would an ion of ca2+ most likely ionically bond with in a 1: 1 ratio?

Explanation:

Atomic number of calcium is 20 and its electronic configuration is 2, 8, 8, 2.

Since it has two extra electrons, therefore, it donate these electrons to an electron deficient atom that needs only two electrons to complete its octet.

Oxygen atom has electronic configuration 2, 6. Hence, it is the atom that needs two electrons to complete its octet. So, it forms a compound of calcium oxide (CaO).

Thus, oxygen will most likely ionically bond with in a 1:1 ratio with .

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
