Answer:
A. PO43-
Explanation:
in the given is buffer . so H2PO4- and HPO42- both are present with equal concentration . Na+ is spectator ion it is also present in the concentration higher than the given species above .
but PO4-3 is not present . so it is lowest concentration
Maybe because meiosis have more chromosomes than mitosis but don't put that on there but that maybe it it because in class we have not went over that yet
Answer:
68 grams
Explanation:
Reaction that produces ammonia when nitrogen and hydrogen reacts is given by :-
+ 3
→ 2N
Clearly ,
When one mole of nitrogen reacts , two moles of ammonia will be produced.
Now,
weight of 1 mole of the Nitrogen = 28.0 grams
In 56.0 grams of the nitrogen , two moles will be present.
Thus , 4 moles of ammonia will be produced .
Weight of one mole of nitrogen = 17 grams.
Thus a total of 17× 4 = 68 grams f nitrogen will be produced.
<span>CO2 and H2Ois released into the blood where there is a lower concentration of both outside of the cells that processed the glucose due to diffusion. Then the blood is transferred to the kidneys to be further processed then stored in the bladder to eventually out of the body by micturition. Sweat can also be used to rid the body of H2O. CO2 leaves the body through the lungs when exhalation is done.</span>
