A. One atom pulls an electron from another atom.

B. Two atoms attain equal electronegativities.

C. One atom becomes more electronegative than another atom.

D. Two atoms share an electron.

Which statement about bonding is correct?

A. Forming bonds releases energy and is exothermic.

B. Forming bonds requires energy and is endothermic.

C. Breaking bonds releases energy and is endothermic.

D. Breaking bonds requires energy and is exothermic.

The bond energy between carbon and oxygen is 358 for a single bond (C–O) and 745 for a double bond (C=O). Why is the bond energy higher for double-bonded carbon and oxygen (C=O)?

A. Additional bonds require less energy to break, so the bond energy is higher.

B. Additional electrons attract each other, decreasing the distance between atoms, and increasing bond energy.

C. Additional electrons repel each other, increasing the distance between atoms, and increasing bond energy.

D. Additional bonds require more energy to break, so the bond energy is higher.

H2 (H–H) combines with O2 (O=O) to become hydrogen peroxide (H2O2) bonded as such: H–O–O–H. Which option shows the difference in total bond energy between the reactants and the products?

A. 1,0801,080

B. −927

C. −153

D. 153

Water (H2O) has two O–H bonds. The electronegativity of oxygen is 3.5, whereas hydrogen is 2.1. Which statement best describes the type of bond this molecule has and how the electrons behave?

A. O–H bonds are polar covalent, and hydrogen pulls the shared electrons toward it.

B. O–H bonds are nonpolar covalent, and oxygen pulls the shared electrons toward it.

C. O–H bonds are nonpolar covalent, and hydrogen pulls the shared electrons toward it.

D. O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it.

Connections is 100% correct but you have question 3 different here all the correct answers:

1. One atom pulls an electron from another atom.
2. Forming bonds releases energy and is exothermic.
3.pull electrons away from other elements.
4. Additional bonds require more energy to break, so the bond energy is higher.
5. −153

Bob Kid,

They are not.
1: one atom pulls an electronic from another atom
2: forming bonds releases energy and is exothermic
3:additional bonds require more energy to break, so the energy is higher
The last 2 are correct

I got #4 wrong from Bri's answers. Here's my answers if anyone needs them.

1. One atom pulls an electron from another atom.
2. Forming bonds releases energy and is exothermic.
3. Additional bonds require more energy to break, so the bond energy is higher.
4. −153
5. O–H bonds are polar covalent, and oxygen pulls the shared electrons toward it.

Dawg fr put our whole assesment up ill let u know when I get them

bri a goat

bri got one wrong...

number 4 is -153 not 153

Answers in different orders

we luv bri <33

@Someone from Connections is 100% Correct

Just took quick check

@study is also correct if you have that quick check
