You might have meant hemiacetal, not hemicetal.
Acetals contain two –OR groups, one –R group and a –H atom. In hemiacetals, one of the –OR groups in acetals is replaced by a –OH group<span>.

Answer: 9000 - 1 significant figure
Explanation: Since you are multiplying, the number with the least amount of significant figures determines the number of significant figures in the answer. The number 9 has 1 significant figure and 1025 and has 4 significant figures so 9 has the fewest significant figures, meaning your answer will be 1 significant figure.
The reaction quotient will be half of the equilibrium constant of the system.
<h3>Equilibrium constant</h3>
The term equilibrium constant refers to a number that shows the extent to which reactants are converted to products when the reaction has attained equilibrium. If the system is not at equilibrium, the number is called the reaction quotient.
If the reaction system is diluted to about twice its original volume, it follows that the reaction quotient will be halved with respect to the equilibrium constant hence the most likely value of the equilibrium constant is about half of the equilibrium constant.

Explanation:
The gas X decays following a first-order reaction.
The half-life () is 25 min. We can find the rate constant (k) using the following expression.
We can find the concentration of X at a certain time () using the following expression.
where,
: initial concentration of X
t: time elapsed
