B) B. is the point where it has maximum potential energy.
Explanation:
- This an example of projectile motion.
- In projectile motion, the path of an object is illustrated in the picture given. In the given picture, the minimum kinetic energy and the maximum potential energy is at B
- B is the point where the object, for example, the ball is reaching its point of minimum kinetic energy which means that after this point the object's downward motion starts.
- Hence, the transition from the upward motion to the downward motion is the point where it has the maximum potential energy.
Answer:
The answer is lithium(LI)
In order of increasing energy,
2s < 3p < 4s < 3d
Answer:
607 ppm
Explanation:
In this case we can start with the <u>ppm formula</u>:
If we have a solution of <u>0.0320 M</u>, we can say that in 1 L we have 0.032 mol of , because the molarity formula is:
In other words:
If we use the <u>atomic mass</u> of (19 g/mol) we can convert from mol to g:
Now we can <u>convert from g to mg</u> (1 g= 1000 mg), so:
Finally we can <u>divide by 1 L</u> to find the ppm:
<u>We will have a concentration of 607 ppm.</u>
