Erm, just 1. Magnesium is an element and that is in its most basic form.
Consider the following homogenous reaction:
aA + bB ⇔ cC + dD
The equilibrium constant is written as:
Kc = ([C]^c * [D]^d) / ([A]^a * [B]^b)
Therefore the equilibrium constant is the ratio of the concentration of the products to concentration of the reactants at equilibrium.
For a heterogenous reaction, the species that are not in the same physical state as the rest of the chemical species are omitted from the expression. Considering the previous reaction, if reactant A was solid and the remaining were gaseous, the expression will be:
Kc = ([C]^c * [D]^d) / [B]^b
Answer:

Answer: The elements with properties intermediate between those of metals and nonmetals are called semimetals (or metalloids).
Answer:
Answer is attached but read below for full explanation.
Explanation:
This reaction is called Hydrolysis of Amides. Amides are carboxylic acid derivatives where the -OH of the carboxylic acid has been replaced by -NH2, -NHR, or -NR2 of an amine. Since the reaction between a carboxylic acid and an amine to give an amide also liberates water, this is an example of a "condensation reaction".
