The 3 kinds of blood vessels are: Ateries, , and veins.

a
ventricles
b
chambers
c
valves
d
capillaries

D, capillaries.

Explanation:

Basically there's three types of vessels. The arteries are are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. There is also the veins, which are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. Then the capillaries, they are very tiny blood vessels, basically so f-cking small that a single red blood cell can barely fit through the thing. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
