Answer:
Heat of solution= - 63KJ/mole
Heat evolved = - 18.82KJ
Explanation:Heat of solution = Heat of solute + Heat of hydration
◇Hsoln = - ( - 7.3 × 10 ^ 2) + ( - 793 ) KJ / mol
◇H soln= - 63 KJ
Use enthalpy of solution equation to determine the enthalpy of solution for LiI
LiI ---> Li^ + + I^-
Molecular mass of LiI=133.85g
The chemical equation for the dissociation will be:
40gLiI (1molLiI)/133.85g LiI - 63KJ/1 mol LiI
18.82KJ
The heat was evolved because the value of enthalpy was negative
Answer:
D: Electromagnetic
Explanation:
Chemical energy is the energy in chemical bonds which is a type of potential energy, eliminating both B and C. While kinetic energy is the energy of motion, photons are a wave/ particle so thinking it would have kinetic energy wouldn't be your fault but light is on the electromagnetic spectrum making D the most likely answer.
Answer:
Liters per second is 0.2 LPS
Liters per hour is 720
Explanation:
Divide the litres by the time, than multiply the time of an hour (in seconds) and than multiply the lps by time of an hour in seconds.
The pressure increases and would explode
