<h3>Answer:</h3>

When a disulfide linkage is formed, the compound containing this new linkage has been <u>oxidized</u>.

<h3>Explanation:</h3>

Oxidation reaction is defined as,

i) Addition of Oxygen Atoms:

When oxygen atom is added to any compound, then the compound is said to be oxidized and the reaction is known as oxidation reaction.

Example:

Oxidation of Alcohols into carboxylic acids:

R---CH₂--OH → R---COOH

ii) Removal of Hydrogen Atoms:

When hydrogen atom(s) are removed from any compound, then the compound is said to be oxidized and the reaction is also called as oxidation reaction.

Example:

Formation of disulfide bond fro thiols:

R--S-H + R--S-H → R---S--S---R

Disulfide bond is quite popular in protein chemistry where it is formed in cystine from cystein amino acids.

The properties which keep the water temperature from changing much are;

water's high specific heat capacity
the large mass of water

<h3>What is specific heat capacity?</h3>

The specific heat capacity is the property of a substance that shows how much its temperature changes when it is exposed to heat.

Thus, the properties which keep the water temperature from changing much are;

water's high specific heat capacity
the large mass of water

saw5 [17]

B is true because liquids are still more compact than gases, although they are loose, they aren't completely free. They also don't have a definite volume, making them assume the shape of their container. As for compression, liquids are harder to compress compared to gases.

1. What is the molarity of a solution prepared by dissolving 3.11 grams of NaOH in

Elena L [17]

The molarity of a solution prepared by dissolving 3.11 grams of NaOH in

enough water to make 300 milliliters of solution is 0. 256 mol/ L

Explanation:

<h3>What is Molarity?</h3>

Molarity (M) is the amount of a substance in a given volume of solution. It is otherwise known as the number of moles of solute in a certain amount of solution.

The unit of molarity is mol/L

<h3>Formula for calculating molarity :</h3>

Molarity = number of moles of solute divided by the volume of the solution\

<h3>Parameters </h3>

Molarity = ?

Number of moles is calculated using :

Mass of the solute = 3.11 grams of NaOH

Molar mass of the solute = Na + O + H

Let's input the atomic numbers of the elements: Na (23) , O (16) , H (1)

Molar mass of NaOH = 23 + 16 + 1 = 40 g/ mol

Number of moles = 3.11 ÷ 40 = 0.077 mol

Volume of the solution is measured in Liters

Let's convert 300 milliters to liters = 300 divided by 1000 = 0.3 Liters

Molarity = 0.077 ÷ 0.3 = 0. 256 mol/ L

Therefore, the Molarity of the solution is 0. 256 mol/ L
