Answer:
d) 2, 4-Dimethylpentane
Explanation:
2, 4-Dimethylpentane is the c_7 compound that gives 3 signals in the broadband proton decoupled ¹³C spectrum.
This compound is classified as an alkane and it's chemical formula is [(CH3C)2CH]2CH2. It is a hydrocarbon that has no odor. When it is combined with other gas compounds it gives high octane fuel.
Remember pH is defined as: pH = -log[H+]
so, substituting
4 = - log[H+]
-4 = log [H+] Take antilog of both sides
10^(-4) = [H+]
[H+] = 1 x 10^-4 M
Answer:
22 cubic inches
Explanation:
We are given;
- Mass of titanium = 3.6 pounds
We are required to determine the volume of titanium in cubic inches
- We need to know the density of titanium;
Density of titanium = 4.51 g/cm^3
1 pound = 453.592 g
therefore, 3.6 pound = (3.6 × 453.592 g per pound)
= 1632.93 g
Therefore;
Volume = Mass ÷ density
= 1632.93 g ÷ 4.51 g/cm^3
= 362.069 cm³
But, 1 in³ = 16.387 cm³
Therefore;
Volume = 362.069 cm³ ÷ 16.387 cm³ per in³
= 22.095 in³
= 22 in³
Thus the volume of titanium is 22 cubic inches
