How does carbon dioxide react with the following?
a. Potassiumb. Lime waterc. Sodium hydroxide
 
a. Potassium combine with \(CO_2\) to form .
 
\(4K+3CO_2→X+C\)
 
X is
 
b. When a limited amount of \(CO_2\) is passed through lime water, it turns milky due to the formation of insoluble .
 
\(Ca(OH)_2+CO_2→Y+H_2O\)
 
Y is
 
c. Sodium hydroxide (base) is converted to  (salt) and water when it reacts with carbon dioxide (acidic).
 
\(2NaOH+CO_2→Z+H_2O\)
 
Z is
