What is the equilibrium constant for the reaction?
1 answer:
Answer: C. 20
Explanation: One equation for the equilibrium constant is . The products are typically on the left side and the reactants on the right.
Given this and the values of each, we can easily plug this in. However, we must multiply the products instead of adding them.
19.888 can be easily rounded to 20, meaning that C is the best answer.
I hope this helps! Pls mark brainliest!! :)

When sodium carbonate is dissolved in water, the equation is .
When carbon dioxide is placed in water, aqueous carbon dioxide is formed:
Some compounds are water-soluble, some are just partially soluble, while others are insoluble in water. Some soluble or partially soluble substances dissociate in water into their component ions. These substances are said to be ionic.
Sodium carbonate, like every other sodium salt, is soluble in water. It dissolves in water to form an aqueous solution of sodium carbonate.
While in solution, sodium carbonate dissociates into its component ions according to the following equation:
Carbon dioxide, on the other hand, does not dissociate in water. Instead, it dissolves in water where most of it remains as aqueous carbon dioxide in equilibrium with a small amount of hydronium ion and hydrogen carbonate ion.
Since the hydronium and hydrogen carbonate ions formed are so minute, the equation of the reaction can be written as:
