Would a sample mean of 14.2 fall within the 95% CI for RR?  

in both reaction #1 and reaction #2, the dissolved hygrogenchloride in the hydrochloric acid solution is part of the system.why is this?

RXN #1: Mg(s) + 2 HCl (aq) --> MgCl2(aq) +H2(g)

RXN#2: MgO(s) + 2HCl(aq) --> MgCl2(aq) +H2O(l)

Given :

2HCl(aq) + Mg(s) -> MgCl2(aq) +H2(g)

Mg(s) + 1/2 O2(g) -> MgO(s)

Mass of 3.00M HCl (diluted in water) : 88.4g

Vol of 3.00M HCl : 87.5mL

Mass of Mg : 0.599g

Total mass: 88.999g
