single because the h didn't have anything in the first place and the h and mg switched. only one thing switched. single

single replacement
the magnesium replaces the hydrogen in the hydrochloric acid
in other words, the Mg replaces the H in the HCl so it's a single replacement
a double replacement would be something like
MgO+2HCl-->H2O+MgCl2
