In order to determine if a reactant is in excess or limiting, we must first know the required amount of reactants. This is referred to as the stoichometric amount of reactant, and it is obtained from the chemical equation.
From the equation, we form a ratio of the reactants. The reactant supplied in excess of that ratio is the excess reactant, while the other is the limiting reactant.
The answer is C. No all cells have cell walls. Prokaryotes don’t have a nucleus or chloroplast. Leaving C to be correct
Answer:
5. 2 Al 3 Cl2 and 2 AlCl3
Cl2 is limiting
(It has the highest coefficients, but that's not always true. If they give you the number of grams for each make sure to work the math out)
6. C
(As the pressure increases there is less volume for the molecules to move around, therefore the molecules will be closer together, allowing for more collisions.)
7. b
(if the temperature is increases so will the rate of the reaction. The increase in temperature will allow for the molecules to move at a faster rate, allowing for more collisions (reactions) between them.
8. d
(dynamic equilibrium is the state at which the reaction is consistently moving, there fore the amounts should remain the same)
9. A
(a catalyst will lower the the pathway of activation energy because it's meant to speed up a reaction)
bro youre on your own after this, im tired
what kind of question is this and idk
