Answer:
The independent variable is the height of the ball that bounces.
The answer is (3) An electron in the third shell has more energy than an electron in the second shell. The energy of electron will increase when number of shell increase.
Number of moles = 2.12 mol C3H8.
1 mol C3H8 = 6.02 × 1023 molecules C3H8.
<span>1 molecule C3H8 = </span>11 atoms.
(3 carbon atoms<span> and 8 hydrogen atoms)</span>
Answer:
exothermic entropy is increased
Explanation:
An exothermic process is one whose rate increases when the temperature is decreased. Hence if a decrease in temperature favours the dissolution of more solute at equilibrium, then the process is exothermic.
Similarly, the dissolution of a solute in a solvent increases the disorderliness (entropy) of the system because of the increase in the number of particles present. Hence once a solute in dissolved, the entropy of the system increases.
Explanation:
The largest water reservoir is the ocean, containing 97.3% of all water on Earth. This is of course salt water and is toxic unless specially treated to remove the salt. The next biggest reservoir are glaciers and polar ice containing just over 2% of the available water.
