Answer:
CaCl₂(s) ⟶ Ca²⁺(aq) + 2Cl⁻(aq)
Explanation:
When the calcium chloride dissolves. the calcium and chloride ions leave the surface of the solid and go into solution as hydrated ions.
Answer: Q=mcΔT
Explanation:
c ethyl alcohol = 2400 J/(kg*K)
T boil ethyl alcohol = 78 C = 351 K
T starting = 17 C = 290 K
m=Q/(c*ΔT)
m= (2400 J)/[(2400 J/kg*K)(351 K -290 K)]
= 0.0028g
