K
Explanation:
Since the blood moves from the body to the right atrium to the right ventricle
Answer:
(A) CHCH
Explanation:
Hello,
Alkynes are formed when triple bonds are formed between carbons, it means that due to the triple bonds, three bonds are already exhausted and carbon atoms need four bonds to attain the octet, for that reason, an extra bond is allowed. Now, such extra bond, when talking about hydrocarbons is filled with hydrogens, for that reason the alkyne should be (A) CHCH as it also accomplishes the following formula which is not accomplished by the rest of the options:

Since n=2, we have:

Which matches with CHCH.
Best regards.
2h-7 I had that before unless I’m tripping but I did rechecked
There are a bunch of elements like:
Zinc, Gold, Silver, Nickel, Aluminum, Indium, Tin, Lead, Platinum, Iron, Cobalt, etc.
Hope it helps! :D
<span>Get into moles first. .0590 grams over 540.8 grams per mole = 1.09 x l0^-4 moles
Sr3(As04)2 = 3 Sr++(aq) plus 2 As04^-3(aq)
Ksp = (Sr++)^3(As04^-3)^2
(Sr++) = 3 X l.09 x l0^-4 = 3.27 x l0^-4
(As04^-3) = 2 x l.09 x l0^-4 = 2.18 x l0^-4
<span>Ksp = (3.27 x l0^-4)^3 (2.18 x l0^-4)^2 which equals 1.66 x 10^-18th
I hope my answer has come to your help. Thank you for posting your question here in Brainly.</span></span>
