5. Balance the equation and state the limiting reagent in the following reaction:
mr Goodwill [35]

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)

The first step in the reaction of Alka–Seltzer with stomach acid consists of one mole of sodium bicarbonate (NaHCO3) reacting wi
Gnesinka [82]

Answer: 5 moles of  H_2CO_3 can be produced from 5 mol NaHCO3 and 9 mol HCl.

Explanation:

The balanced chemical reaction is:

NaHCO_3+HCl\rightarrow H_2CO_3+NaCl

According to stoichiometry :

1 mole of NaHCO_3 use 1 mole of HCl

Thus 5 moles of NaHCO_3 use=\frac{1}{1}\times 5=5moles  of HCl

Thus NaHCO_3 is the limiting reagent as it limits the formation of product and HCl is the excess reagent.

As 1 mole of NaHCO_3 give = 1 mole of H_2CO_3

Thus 5 moles of NaHCO_3 give =\frac{1}{1}\times 5=5moles  of H_2CO_3

5 moles of  H_2CO_3 can be produced from 5 mol NaHCO_3 and 9 mol HCl.

What adaptation do lungfish have te help them walk and live on land?
Viktor [21]

Answer: biological adaptation

Explanation:

lungfish's lung is a biological adaptation. A biological adaptation is a physical change in an organism that develops over time. Like all fish, lungfish have organs known as gills to extract oxygen from water. The biological adaptation of the lung allows lungfish to also extract oxygen from the air.

I hope this helps :).
