Equations

Question 1

What is the general equation for the reaction of Ca/St/Ba with cold water?

Answer 1

Xx (s) + 2H2O(l)–> Xx(OH)2 (aq) + H2(g)

Question 2

What is the equation for the test for CO2 gas with limewater?

Answer 2

CO2(g) + Ca(OH)2 (aq) –> CaCO3 (s) + H2O(l)

Question 3

What is the equation for Mg(OH)2 being used as an indigestion medication? (normal and ionic)

Answer 3

Mg(OH)2 (s) + 2HCl (aq) –> MgCl2 (aq) + 2H2O (l)

Mg(OH)2 (s) + 2H+ (aq) –> Mg2+ (aq) + 2H2O (l)
