Answer:
Explanation:
mass of the solution = volume x density = 200 x 1 = 200 gm
heat absorbed = m x s x Δ t , s is specific heat , Δt is rise in temperature
= 200 x 4.18 x ( 31.3 - 24.6 )
= 5601 J .
This is the enthalpy change required.
Option C. A compound being separated into 2 elements represents a chemical change.
No it means that the liquid is way different then water<span />
carbon won't have same number of valence electrons as others
