Explanation:
Glad to help :)
The factors that can determine the outcome of a "neutralization reaction" include:
__________________________________________________________
1) temperature;
2) concentration (of the solution);
3) type of acid used;
4) type of alkali used;
5) type of reaction;
(e.g. whether the reaction is "endothermic" or "exothermic");

Answer:
= 17% (v/v)
Explanation:
% by Volume = (Volume HCl / Volume of Solution)100%
= 15ml/(75ml + 15ml) x 100% = 16.66666667% (calculator answer)
= 17% (v/v) 2 sig figs. based on volume values given.
Answer:
Density = 19.3 g/cm³
Explanation:
D = m/v
m = 965 g
v = 50 cm³
so,
965 g / 50 cm³ = 19.3g/cm³
Hope this helps!
