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:
Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.

It’s gonna be water and wind after many years of harsh winds and water the rock will slowly start to break or even become smooth ! That’s why you might find those at the lake ! so c!
Answer:
Fastest C. Reaction time is faster
Slowest A. Reaction time is slower and it takes longer to finish
Explanation:
Total pressure = 
= 0.78 + 0.21 + 2.67 * 10⁻¹⁶
<h3>
= 0.99 atm</h3><h3>What is pressure?</h3>
The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental quantifiable variables of this phase of matter, pressure, is a property shared by all gases.
