The dots in the Lewis dot structure symbolize an atom's elements.
<span>Since Na^+ is a positive ion (cation) with a charge of +1, it indicates that it has lost an electron. </span>
<span>Since Na had one electron, to begin with, and it is now lost, Na^+ will have no dots. However, the charge must still be written as a superscript. </span>
<span>Therefore, the Lewis dot structure for Na^+ is just Na^[+] </span>
Answer: 0 m
Explanation:
Let's begin by stating clear that movement is the change of position of a body at a certain time. So, during this movement, the body will have a trajectory and a displacement, being both different:
The trajectory is the <u>path followed by the body</u> (is a scalar quantity).
The displacement is <u>the distance in a straight line between the initial and final position</u> (is a vector quantity).
According to this, in the description Matthew's home is placed at 0 on a number line, then he moves 10 m to the park (this is the distance between the park and Mattew's home), then 15 m to the movie theatre until he finally comes back to his home (position 0). So, in this case we are talking about the <u>path followed by Matthew</u>, hence <u>his trajectory</u>.
However, if we talk about Matthew's displacement, we have to draw a straight line between Matthew's initial position (point 0) to his final position (also point 0).
Now, being this an unidimensional problem, the displacement vector for Matthew is 0 meters.
Answer:
False
Explanation:
It depends on the density of an object, not the wight.
I believe the answer would be "Different Colors," hope this helps :)
