Answer:
<h3>The answer is 3.85 s</h3>
Explanation:
The time taken can be found by using the formula
![t = \frac{d}{v} \\](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7Bd%7D%7Bv%7D%20%20%5C%5C%20)
d is the distance covered
v is the velocity
From the question we have
![t = \frac{50}{13} \\ = 3.846153...](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7B50%7D%7B13%7D%20%20%5C%5C%20%20%3D%203.846153...)
We have the final answer as
<h3>3.85 s</h3>

8. Thermal Energy
Answer:
CH2O
Explanation:
Firstly, we need to convert the masses of the elements to percentage compositions. This can be done by placing the mass of each element over the total mass multiplied by 100% . We can start with carbon.
C = 5.692/14.229 * 100 = 40%
O = 7.582/14.229 * 100 = 53.29%
H = 0.955/14.229 * 100 = 6.71%
We then proceed to divide each percentage composition by their atomic mass of 12, 16 and 1 respectively.
C = 40/12 = 3.333
O = 53.29/16 = 3.33
H = 6.71/2 = 6.71
Dividing by the smaller value which is 3.33
C = 3.33/3.33 = 1
O = 3.33/3.33= 1
H = 6.71/3.33 = 2
The empirical formula of the compound ribose is CH2O

Answer:
d. each of the above (A, B, and C) occurs.
Explanation:
When an ionic species dissolves in water , the ionic compound dissociates into cation and anion , and the cation interacts with the negative end of the water molecules , and the anion interacts with the positive end of the water molecule .
During the process of dissolution , the interaction between , solvent - solute overcome the interaction between solute - solute molecules .
Hence , From the question , all the statement given are correct .
