Ag ^+(aq) + Cl^-(aq) ----> AgCl(s)
Answer:
True
Explanation:
Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed.
FeSO4 (s) plus 4H2 (g) gives 3Fe(s) plus 4H2O(l)
from the equation above i mole of FeSO4 reacted with 4 mole of H2 gas to give 3 moles of iron and 4 moles of water.There is a relationship between volume and equilibrium shift. Decrease in volume favor the side with less moles of a gas. since hydrogen is a gas a decrease in volume favor the forward reaction hence more Fe is produced.
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
Explanation:
Air has a heat capacity of about 700 Joules per kg per °K and a density of just 1.2 kg/m3, so its initial energy would be 700 x 1 x 1.2 x 293 = 246,120 Joules
