Answer:
This question is incomplete
Explanation:
This question is incomplete but there are two parts to this question that can generally be answered without the missing parts.
(1) If a CO₂ molecule starts out surrounded by other CO₂ molecules, does this influence how quickly it will reach the other side of the leaf?
What controls how quickly a CO₂ molecule/molecules enter into the leaf to the other parts of a leaf is the stomata on the leaf. Stomata are tiny openings on a plant leaf that allows for gaseous exchange (the release of oxygen and the absorption of CO₂) in the leaf.
(2) Collisions influence how molecules move, but do molecules only collide with other molecules of the same substance? NO
One of the kinetic theory of gases states that gases collide with one another and against the walls of the container. <u>It should however be noted that, gas molecules of a particular substance can collide with gas molecules of other substances</u>, so far they are within the same container.
Answer:
Molarity is a unit for expressing the concentration of a solution
Explanation:
Molarity is used to express the concentration of a solution. Also known as molar concentration, molarity is the number of moles of solute (the material dissolved) per liter of solution. It measures the concentration of a solution. The molarity of a solution is calculated by taking the moles of solute and dividing by the liters of solution. Hence, Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution.
Molarity is commonly expressed as molar. Molar also refers to the unit of concentration called molarity, which is equal to the number of moles per liter of a solution. In chemistry, the term most often refers to molar concentration of a solute in a solution. Molar concentration unit also implies the units mol/L or M.

Answer: I am not sure but I think its fossil fuel - filling oil and mining coal cause few environmental problems,not dependent on weather condition, not chemical hazard or flammable hazard. Wind and solar - inexpensive, increase carbon footprint and easily stored and transported
