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.
I think it is B, but i am not sure
Invasive species can do all sorts of damage to an existing ecosystem, including changing habitats and starving native animals of food and resources.
<h3>What is an invasive species?</h3>
An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.
Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitats for native wildlife.

Answer:
44.6millilitres
Explanation:
Using the general gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
V1 = initial volume (L)
T1 = initial temperature (K)
P2 = final pressure (atm)
V2 = final volume (L)
T2 = final temperature (K)
According to this question;
V1 = 30mL
T1 = 273K (STP)
P1 = 1 atm (STP)
V2 = ?
T2 = 300K
P2 = 75.0 kPa = 75 × 0.00987 = 0.74atm
Using P1V1/T1 = P2V2/T2
1 × 30/273 = 0.74×V2/300
30/273 = 0.74V2/300
Cross multiply
300 × 30 = 273 × 0.74V2
9000 = 202.02V2
V2 = 9000/202.02
V2 = 44.55
V2 = 44.6millilitres.
