Answer:
N2 (g) + 3 H2 (g) -> 2 NH3 (g)
Explanation:
First, write the reactants on the left and the products on the right side. Also, add the states of matter after the reactants and products. Note, nitrogen gas is written as N2 and hydrogen gas is written as H2, not N or H.
N2 (g) + H2 (g) -> NH3 (g)
Next, balance the equation! Since there are two nitrogens on the left, add a two to the product NH3. Now there are 6 hydrogens on the right side. To balance that, add a 3 to the H2.
N2 (g) + 3 H2 (g) -> 2 NH3 (g)
Double checking, there are 2 nitrogens and 6 hydrogens on each side.
Success!

Explanation:
Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. My findings said that ammonia is a weak base, potassium hydroxide is a strong base, vinegar is a weak acid and ethyl alcohol is a weak acid.
Vinegar and ethyl alcohol are eliminated as they are acids. The question is on bases.... Potassium hydroxide is a strong base. So we are left with ammonia, being a weak base.

Answer:
CaF2
Explanation:
Calcium fluoride is a solid formed by the chemical combination of Calcium (Ca) and Fluorine (F). Two molecules of fluorine (F2) and one molecule of Calcium (Ca) are needed to form the Calcium Fluoride molecule.
An ionic bond is formed between the Calcium and Fluorine atoms i.e. electrons are transferred from calcium atoms to fluorine atoms. The calcium ion is a cation with formula; Ca2+ while fluorine is an anion with formula; F-. Hence, it takes two molecules of Fluorine ion (F-) to form a relatively stable and neutral molecule with 1 molecule of Calcium ion (Ca2+).
