Explanation:
i believe is this a test
please mark this answer as brainlest i got the answer from someone by the way which is my sis
but forget all of that
please mark brainlest
Sr(NO3)2 ---> Sr²⁺ + 2 NO3⁻
from the reaction 1 mol 1 mol 2 mol
from the problem 0.5 mol 0.5 mol 1 mol
Answer:
I think your answer is unrelated
Answer:
See explanation
Explanation:
The compound CHOOH is more acidic than CH3CH2NH2 because the carbonyl group is strongly electron withdrawing hence electron density is withdrawn from the O-H bond making easier for the proton to be lost.
CH3CH2NH2 is more basic than CHOOH because of the lone pair of electrons on the nitrogen atom of CH3CH2NH2. This is reinforced by the electron pushing effect of the CH3CH2-group thereby making the amine more basic(able to abstract a proton) than CHOOH .
The images attached show the structures of CHOOH and CH3CH2NH2 . They are able to react because of the proton in CHOOH and the lone pair of electrons in CH3CH2NH2 as shown in image III. This is a reaction in which the lone pair on CH3CH2NH2 abstracts a proton from CHOOH leading to the formation of the products as shown.
