Answer:
The number of carbon atoms in the organic compound is 16.
Explanation:
The relative intensity of M + 1 peak (relative to M = 100) in organic compounds can be predicted by the following formula:
[M + 1] = (number of C x 1.07) ---------------------------------------------------- (1)
This formula can also be used to determine the number of carbon from the given intensity. But first, the intensity of [M + 1] relative to [M] = 100 needs to be determined, for which, consider the following calculations,
![[M+1]=(\frac{M+1}{M}) (100)](https://tex.z-dn.net/?f=%5BM%2B1%5D%3D%28%5Cfrac%7BM%2B1%7D%7BM%7D%29%20%28100%29)
![[M+1]=(\frac{7.022}{40.58}) (100)](https://tex.z-dn.net/?f=%5BM%2B1%5D%3D%28%5Cfrac%7B7.022%7D%7B40.58%7D%29%20%28100%29)
![[M+1]=17.30](https://tex.z-dn.net/?f=%5BM%2B1%5D%3D17.30)
Using equation 1 we get,
![number of C=\frac{[M+1]}{1.07}](https://tex.z-dn.net/?f=number%20of%20C%3D%5Cfrac%7B%5BM%2B1%5D%7D%7B1.07%7D)
or number of C = 16
The remaining value, 0.168, can be due to the isotopes of hydrogen and oxygen in the organic compound.
The velocity of a 485 kg elevator that has 5900 J of energy is 108.6 m/s
<h3>What is the velocity of the elevator?</h3>
A moving elevator possesses kinetic energy due to its motion.
The velocity of the elevator is calculated from the formula of kinetic energy.
The kinetic energy formula is : Kinetic energy = ¹/₂mv₂
The velocity, v = √2KE/m
v = √(2 * 5900/485)
v = 108.6 m/s
In conclusion, the velocity of the elevator is calculated from the kinetic energy and mass of the elevator.

Answer:
Electrolyte
Explanation:
A compound that conducts electricity when dissolved in water would most likely be classified as electrolyte.
The ionic compound in solid form do not conduct the electricity but when dissolve in water they separated into ions and have ability to conduct the electricity because of mobile ions that move freely and allow the charge to flow.
The ionic compounds are called electrolyte and electrolyte solution is formed when they dissolve in water.
For example when sodium chloride is placed into water it split into ions and conduct electricity because of mobile ions.
Chemical equation:
NaCl → Na⁺ + Cl⁻
Answer:
24.9mL of the stock solution are required
Explanation:
To solve this question we have to find, as first, the moles of HCl that we need to prepare the desire solution. These moles are taken from the stock solution as follows:
<em>Moles diluted solution:</em>
500.0mL = 0.5000L * (0.613mol / L) = 0.3065 moles HCl
As these moles comes from the 12.3M HCl solution, the volume that we need of the stock solution is:
<em>Volume stock solution:</em>
0.3065 moles HCl * (1L / 12.3moles) = 0.0249L 12.3M HCl =
<h3>24.9mL of the stock solution are required</h3>
