Answer: false 100
Explanation:
if this is the true or false test here
The correct answer is A.) dilute
Equation: 2K + S --> K2S
Chemical formula: K2S
Answer:
All of the physical and biological factors in it's environment, I think this is the answer, but I might be wrong.
Explanation:
I learned it in my school's Science class
Delta H of solution = -Lattice Energy + Hydration
<span>Delta H of solution=- (-730)+(-793) </span>
<span>Delta H of solution= -63kJ/mol </span>
<span>Now we find moles of LiI: </span>
<span>10gLiI/133.85g=.075moles </span>
<span>multiply moles to the delta H of solution to cross cancel moles. .75moles x -64kJ/mol =4.7</span>
