Explanation:
An ionic compound is formed when one atom donates one or more electrons to one or more atoms of another element. Calcium has two valence electrons, which are donated to an atom of oxygen. So, an ionic compound is formed in the reaction involving one calcium atom with an oxygen atom.
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is more acidic than CH3CH2NH2 because the carbonyl group is strongly electron withdrawing hence electron density is withdrawn from the O-H bond making easier for the proton to be lost.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.
Answer:
the answer is d.
Explanation:
because the core is deepest then is the mantle and the lithpsphere is last .
