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.
Answer:
Here is your answer: Tin,
Explanation:
Which of the following elements probably has the most properties in common with lead (Pb)? Tin (Sn).
Answer:
<em>atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.</em>

Answer:
- 0.07 °C
Explanation:
At constant pressure and number of moles, Using Charle's law
Given ,
V₁ = 439 mL = 0.439 L ( 1 L = 0.001 mL )
V₂ = 0.378 L
T₁ = 317.15 K
T₂ = ?
Using above equation as:
The conversion of T(K) to T( °C) is shown below:
T( °C) = T(K) - 273.15
So, <u>T = 273.08 - 273.15 °C = - 0.07 °C</u>
PH value of 0.10 m of HBr, a strong acid.
When dissolved in water it gives H+ and Br-, so H+ is the concentration.
pH = - log H+) => pH = - log (0.10) = -(-1) = 1
HF and HC2H3O2 are weak acids. They both will have pH value greater than 1 as they ionize in solution.
