The percentage composition of CF4 is %C = 13.64% and %F = 86.36%
The solution are as follows:
Molar mass of CF4 = 88
<span>molar mass of C = 12 </span>
<span>molar mass of F = 4x19 = 76 </span>
<span>% C = 12/88 x 100 = 13.64% </span>
<span>% F = 76/88 x 100 = 86.36%</span>
Answer:
The most stable conformer would be the anti-conformer when the substituent methyl groups are farthest away from each other.
Explanation:
Isomers are chemical compounds with the same molecular formula but with different molecular structures.
Conformers are a special type of isomers that produce different structures when the substituents of a Carbon-Carbon single bond (C-C) are rotated.
In 2,3 dimethyl butane, the substituent methyl groups are located around the second and third Carbon to Carbon single bond.
To achieve a stable configuration, the methyl group substituents need to be as far apart as possible (that is, in an anti-position) to minimise repulsion.
The closer the methyl groups are to each other, the more they repel each other and the more unstable the conformer becomes.
For this problem we assume that oxygen is an ideal gas. So, we use the equation PV=nRT where P is pressure, V is the volume, n is the number of moles, R is a universal constant and T is the temperature. We first solve for the number of moles n. Then, using the molar mass of oxygen we convert it to grams.
PV=nRT
n = PV / RT
n = 3.23 (8.5) / 0.08206 (32+273.15)
n = 1.0964 mol
mass = 1.0964 mol (32g / 1 mol) = 35.09 g O2
Answer:
Ammonium Lauryl Sulfate is a mild surfactant.
Explanation:
Ammonium Lauryl Sulfate is an anionic surfactant. A surfactant is a compound that helps in mixing the matters (solid, liquid, and gas) with one another. It functions by decreasing the surface tension between the two matters. Primarily they are used to mix water with oil. After getting mixed, they help in washing the dirt away.
Ammonium Lauryl Sulfate is a mild surfactant as compared to surfactant as compared to Sodium Lauryl Sulfate in terms of irritation. It is used as one of the components in cosmetics and toiletry formulations. It acts as a surface mixing agent for foaming, wetting and dispersing.
