Answer:

Approximately two elements may combine to form compounds, but there may be cases where more than two elements combine to form compounds.

Explanation:

In chemistry, the term compound is defined as a substance formed by the union of at least two elements. There are cases where more than two elements come together to form a compound, but we can say that approximately two elements are used for compound formation. An example of compound is shown in the chemical formulas H2O and FeS represent the compounds water and ferrous sulfide.

Answer:

[A]²

Explanation:

Since the formation is independent of D, D is 0 order.

Since a quadruples when it is doubled it can be written as

2A^X= 4

To find the unknown power we can assume A= 1 to make the math simple. So When a = 2 (Because you doubled it) raised to X power it will equal 4

so the unknown power is 2
