Sample Response: The change in her position (from beginning to end), along with the direction, is considered her displacement. T
kykrilka [37]

The sample response given in the question is right.

To find the answer, we need to know more about the distance and displacement.

<h3>How distance differ from displacement?</h3>
  • Displacement is the shortest distance between the initial and final points of a body.
  • It is the change in position with a fixed direction.
  • Displacement is a vector quantity and can be positive, negative or zero values.
  • Distance is the length of actual path of the body between initial and final positions.
  • It's a scalar quantity and it can be positive or zero.
  • The magnitude of displacement is less than or equal to the distance travelled.

Thus, we can conclude that the given sample response is right.

The answer is 
<span>2PbS(s) + 3O2(g) = 2PbO(s) + 2SO2(g)

Your answer is not yet balanced because you have 3 oxygen atoms. it should be balanced by multiplying both side by 2 such as the balanced equation I made. To check it, I will explain why your answer is not yet balanced.

check: (from your equation)
</span> 1-Pb-1
 1-S-1
2 -O-3
the difference between the reactant and the product of Oxygen will prove that it is not yet balanced.

If you use 2PbS(s) + 3O2(g) = 2PbO(s) + 2SO2(g), to check it:
2-Pb-2
 2-S-2
6 -O-6
then this is now balance
