How would we represent the reaction of #"magnesium bicarbonate"# with #"hydrochloric acid"#?

Answer 1

Are you asking how many equiv of acid we add to neutralize #Mg(HCO_3)_2#?

#Mg(HCO_3)_2(aq) +2HCl(aq) rarr MgCl_2(aq) + 2CO_2(g) + 2H_2O(l)#

#HCO_3^(-) + H_3O^+ rarr CO_2(g)uarr + 2H_2O(l)#

We cannot accept these equations as a representation of chemical (i.e., physical) reality if they are not balanced with respect to mass and charge.

The following equation can be used to represent the reaction between magnesium bicarbonate and hydrochloric acid: Mg(HCO3)2 + 2HCl -> MgCl2 + 2H2O + 2CO2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
