How does the number of products in a synthesis reaction compare with the number of reactants?
2 answers:
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Synthesis reaction is defined as the reaction in which two or more substances combine in their elemental state to form a single compound.
The general equation representing this reaction follows:
As, number of reactants in this type of reaction will always be more bacuse a single product is forming in this reaction.
Thus, the correct answer is Option B.

Answer:
pH = 2.03
Explanation:
The pH can be calculated using the following equation:
(1)
The concentration of H₃O⁺ is calculated using the dissociation constant of the next reaction:
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺
1.00 M
Solving the above equation for H₃O⁺, we have:
(2)
The dissociation constant is equal to:
Now, by solving the equation of the solubility product for Herbigon, we can find [CH₃COO⁻]:
CH₃COOX ⇄ CH₃COO⁻ + X⁺
5.00x10⁻³ M
By entering the values of [CH₃COO⁻] and Ka, into equation (2) we can calculate [H₃O⁺]:
Hence, the pH is:
Therefore, the pH must be 2.03 to yield a solution in which the concentration of X⁺ is 5.00x10⁻³M.
