According to the balanced equation of the reaction:
2C2H2 + 5O2 → 4CO2 + 2H2O
So we can mention all as liters,
A) as we see that 2 liters of C2H2 react with 5 liters of oxygen to produce 4 liters of CO4 and 2 liters of H2O
So, when we have 75L of CO2
and when we have 2 L of C2H2 reacts and gives 4 L of CO2
2C2H2 → 4CO2
∴ The volume of C2H2 required is:
= 75L / 2
= 37.5 L
B) and, when we have 75 L of CO2
and 4CO2 → 2H2O
∴ the volume of H2O required is:
= 75 L /2
= 37.5 L
C) and from the balanced equation and by the same way:
when 5 liters O2 reacts to give 4 liters of CO2
and we have 75 L of CO2:
5 O2 → 4 CO2
?? ← 75 L
∴ the volume of O2 required is:
= 75 *(5/4)
= 93.75 L
D) about the using of the number of moles the answer is:
no, there is no need to find the number of moles as we called everything in the balanced equation by liters and use it as a liter unit to get the volume, without the need to get the number of moles.

the object reflects blue light and absorbs rest of the spectrum.
I think it is the bottom left :)
Explanation:
Cytoplasm- a sticky jelly like substance that helps the other structures stay in place.
Nucleus- the control center of the cell. It tells everything what to do.
Mitochondria- it gives the cell energy
Endoplasmic reticulum- it delivers things in and out of the cell
Ribosomes- give the cell protein
Golgi apparatus- it collects unwanted things in the cell to ship out of the cell
Vesicles- can help transport materials that an organism needs to survive and recycle waste materials.
Lysosomes- they are like a big sac of acid that dissolve things
Cell membrane- the gateway of the cell; it lets things in and out

That'd be a comet, which is composed of ice and dust. I hope this helps!
