What is true of saturated fatty acid chains?

Chemistry

B. They contain only single covalent bonds

Although the side chains may contain double bonds, the main chain of a saturated fatty acid molecule contains only single covalent bonds, which is why it is referred to as being "saturated".

The best option among all these is b option. They contain only single covalent bonds.

Yasmin's teacher tells her that the solubility of salt is 360 g/L at room temperature (25 °C). How can Yasmin make an unsaturate
Bezzdna [24]

Answer:

By adding less amount or quantity of the salt (solute), than the medium (solvent) can dissolve at a particular temperature that is to make an unsaturated solution at room temperature, Yasmin should add less than 360 g of salt to one liter of the solvent

Explanation:

An unsaturated solution is one that consists of less than the maximum mass or quantity of the solute that it is capable of dissolving.

Arrange the molecules in order from strongest intermolecular force to weakest.
motikmotik

Answer:- C_4H_1_0>C_3H_8>C_2H_6>CH_4

Explanations:- Alkanes are non polar molecules as these only have carbons and hydrogens. Electron negativity difference of C and H is very low and it makes them non polar. These have weaker London dispersion forces.

The forces of attraction becomes stronger in alkanes as the number of carbon increases because the surface area as well as molecular weight of the alkanes increases with an increase in number of carbons.

Butane has four carbons, propane has three carbons, ethane has two and methane has only one carbon, So, the strongest to weakest order of inter molecular forces is butane > propane > ethane > methane .

A compound is 2.00% H by mass, 32.7% S by mass, and 65.3% O by mass. What is its empirical
Katarina [22]

Answer:

empirical formula: H_2SO_4

2 g H

32.7 g S

65.3 g O

Explanation:

Like the problem said, the first thing we can do is calculate the mass of each of the 3 elements in a 100-gram sample:

- 2.00% * 100g = 2 g H

- 32.7% * 100g = 32.7 g S

- 65.3% * 100g = 65.3 g O

Now we need to find the empirical formula from these. To do so, convert all of those masses into moles by using the molar mass for each element:

- the molar mass of H is 1.01 g/mol

- the molar mass of S is 32.06 g/mol

- the molar mass of O is 16 g/mol

2 g H ÷ 1.01 g/mol = 1.98 mol H

32.7 g S ÷ 32.06 g/mol = 1.02 mol S

65.3 g O ÷ 16 g/mol = 4.08 mol O

Our ratio of H : S : O is now:

1.98 mol : 1.02 mol : 4.08 mol

Divide them all by the smallest number, which is 1.02:

1.98/1.02  :  1.02/1.02  :  4.08/1.02

1.94 : 1 : 4

1.94 ≈ 2

So:

2 : 1 : 4

Thus, the empirical formula is: H_2SO_4.
