<span>It has to be 100mL as total mass = 400g
Moles HCl = 0.05; moles Ba(OH)2 = 0.15
If volume HCl is 100mL then moles HCl = 0.05 and Ba(OH)2 is excess
If 2 moles HCl release 118 kJ then
0.05 moles HCl releases 2.95 kJ
q = cm deltaT
c=4.18 x 10-3 kJ/c.g
DeltaT = q/cm = 2.95/4.18 x 10-3 x 400 = 1.76 degrees rise so final temp = 1.76+ 25</span>
Answer:
Explanation:
I need to see the graph please
D. Toxic , the other options do not refer to something necessarily harmful to the human body or poisonous. Human hair is ignitable, acid in the stomach corrodes food through chemical reactions so toxic is the only option left.
