Correct answer: <span>Dot-and-cross-diagram
</span>
Dot-and-cross diagrams are used to represent covalent bonds. The shared electron from one atom is shown as a dot, while the shared electron from the other atom is shown as a cross.
When drawing dot-and-cross diagrams for covalent bonds, you only need to show the electrons in the highest occupied energy level, as only these are involved.

Answer:
-5
Step-by-step explanation:
-2.5y + 8y - 10.5
= 5.5y - 10.5y
= -5y
The coefficient of the variable y is -5.
Answer:
B) Multiply each side by 3
Step-by-step explanation:
This is how to solve for h
+ 7 = 5 (First Step --> Subtract 7 from both sides)
= - 2 (Second Step --> Multiply both sides by 3 to cancel out the denominator and to find just h)
h = -6
