Answer: Option (a) is the correct answer.
Explanation:
A dissociation reaction is defined as the reaction in which a compound beaks down into two or more different parts.
For example, molecular formula of water is 
and when it dissociates then it given hydrogen ion and hydroxide ion.
Therefore, dissociation reaction for water is as follows.
Thus, we can conclude that out of the given options is the correct equation for the dissociation of water.
<span>In the field of science, usually, the product of an experiment is
computed ahead to understand if it reached a specific objective. It would reach
greater than 100% of percent yield if the factors include faster reaction rates;
proper handling of the reactants, no outside contaminants, and the procedure of
the experiment is followed smoothly. It would reach lesser than 100% percent yield
if the experiment is not followed, external factors such as contamination from
the environment (wind, moisture, etc). </span>
Answer:
Heat is the sum of all the kinetic energies of all the molecules of an object, while temperature is the average kinetic energy of the molecules of an object
When multiplying quantities, the basis for the number of significant answers for your answer is the least number among the given data. In this problem, 2.31 has 3 sig figs, 4.9795x10³ has 5 sig figs, and 1.9971x10⁴ has 5 sig figs. So, we follow 3 sig figs.
<span>(2.31)(4.9795X10^3)/(1.9971X10^4) = <em>23.0</em></span><em>×10⁷</em>
