Answer:
C
Explanation:
Temperature is directly related to kinetic energy (KE). As we raise temperature, we are raising KE, as well. Particles with more KE move more quickly and with more force.
This means that these particles are more likely to collide with each other and react to allow the chemical reaction to follow through. In turn, if the chemical reaction is more likely to go to completion, the reaction rate increases, eliminating A and B.
The concentration of the solute is not affected by the temperature; in other words, temperature will not increase or decrease the amount of solute in the solution, so eliminate D.
Thus the answer is C.

Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. I hope this helps. :)
Answer:
When the fuel is burnt, the hot gas rushes out of the rocket due to the great heat and pressure produced by the release of chemical energy in burning. Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another.
Explanation:
Answer:
7,881 g/L
Explanation:
Iron volume = 30.58 mL - 29.40 mL = 1.18 mL
1.18 mL / 1000 mL = 0.00118 L
Iron density = mass/volume
= 9.3g / 0.00118 L
= 7,881 g/L
The cycling of water and nutrients through an ecosystem is powered mainly by the sun, while the cycling of blood in the cardiovascular system "powered" by the heart.
