When a solid (solute) comes in contact with the liquid (solvent), the solute goes about C) dissolution, in which the solid dissolves into the liquid.

Answer:
KE = PE at half the table Height:
Explanation
AT ANY POINT IN THE BOOK'S FALL,
TOTAL E = PE +KE
THE TOTAL E IS CONSTANT
Before the book is pushed off, the total energy is potential
TOT E=PE =MGH
BEFORE THE BOOK HITS THE GROUND, THE TOTAL E IS KINETIC
TOT=KE = MVXV/2
WHEN KE = PE
KE+PE =<u> MGH (STARTING ENERGY SINCE E IS CONSERVED)</u>
<u>OR PE+ PE = MGH</u>
<u>OR MGH' + MGH' =MGH</u>
<u>OR 2H' =</u>H
H' (NEW HEIGHT) =H/2
No, its not possible. Let's go back to 4th grades' basic science.
"Energy can not be created or destroyed."
This applies to everything, even atoms!
Have a great day! ❤
Answer:
C. The less energy the organism requires, the more efficient the energy transfer.
The balanced chemical reaction is:
<span>2NH3(aq) + H2SO4(aq) = (NH4)2SO4(aq)
</span>
We are given the amount of sulfuric acid to be used for the reaction. This will be the starting point of our calculations.
60.0 mol H2SO4 ( 1 mol (NH4)2SO4 / 1 mol H2SO4 ) ( 132.14 g (NH4)2SO4 / 1 mol (NH4)2SO4 ) = 7928.4 g <span>(NH4)2SO4</span>
