As Bond energy is between carbon and oxygen the is 358 for a single bond of C-0 and 745 for a double bond is the c=0.
- In the first step the one atom pulls the electron from another atom
. In the second step that is forming bonds releases energy and is the exothermic
. In the third step they pull electrons away from other elements
.
- In the last step the additional bonds is needed more energy to make or break, so the bond energy is very higher Hence the -153.
Learn more about the energy between carbon and oxygen is 358.

Answer:
The answer is in the explanation
Explanation:
Single displacement reactions: In these reactions, a more reactive element kicks out a less reactive element from a compound.
Ex. Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
In this example, Zn is more reactive than H, then Zn displaces H from the compound.
Double displacement reactions: In these kind of reactions 2 elements are displaced from the different compounds, these elements interchange positions.
Ex. CuCl2(aq) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 AgCl(s)
In the example, Cu displaces Ag and Ag displaces Cu, they interchange positions.
Answer:
It would tend to gain one electron and form a -1 ion. Aluminum is in the fifth column and therefore has 5 electrons in its outermost shell. It would tend to lose three electrons and form a +3 ion.
Explanation:
Answer:
d) tetrahedral
Explanation:
Given that the central atom is attached to the four group.
Number of bond pairs = 4
Number of lone pairs = 0
The formula is .
According to VSEPR theory,
The central atom has 4 bond pairs and 0 lone pair. Hybridization is sp³. The geometry is tetrahedral which has an angle of 109.5°.
Methane, posses a tetrahedral geometry as four atoms of hydrogen are attached to the central atom which is carbon.
Hence. D option is correct.
