Calculate the molar mass of glycerin, C3H5 (OH)3

Answers

Answer 1

Answer:

92.0 g/mol is the molar mass of glycerin, C $_3$ H $_5$ (OH) $_3$ . Since it isn't possible to directly quantify the number of moles, molar mass acts as a link across the mass of a substance.

The mass of a certain chemical element and chemical compound (g) multiplied by the substance's molecular weight (mol) is known as the molar mass. By multiplying the standard atomic weights (in g/mol) of the component atoms, one may get the molecular weight of a compound. As well as the number of moles. the product of a substance's mass (measured in grammes or molecules) and its molecular weight (mol).

C $_3$ H $_5$ (OH) $_3$ = 12 × 3 + 1 × 5 + 16 × 3 + 1 ×3 = 92.0 g/mol

Increasing the ? of a solvent increases the solubility of the solute

Answers

There are a lot of ways to increase the solubility of the solute. Increasing the temperature, mixing time and surface area of a solvent increases the solubility of the solute

The answer is temperature

At STP, oxygen exists in two forms, O2(g) and O3(g). These two forms of oxygen have 1. different molecular structures and different properties 2. different molecular structures and the same properties 3. the same molecular structure and different properties 4. the same molecular structure and the same properties

Answers

Answer: option 1. different molecular structures and different properties.

Explanation:

1) O₂ and O₃ are different forms of the same element, in the same physical state (gaseous).

2) That is what is called allotropes.

3) The definition of allotropes is different forms of an element with different structures and different properties in the same physical state.

Graphite and diamond is other example of common allotropes.

4) O₃ and O₂ have the same kind of atoms (oxygen), but they are bonded differently (different structure, one molecule has 3 atoms, other 2 atoms) which conferes them different properties (e.g. different odor, different chemical reactivity).

At STP, oxygen exists in two forms, O2(g) and O3(g). These two forms of oxygen have different molecular structures and different properties. The answer is number 1. The rest of the numbers do not answer the question above.

The oxidation # (charge) of an element called "lindenium "Ld is + 1 and the oxidation # (charge) of an element called "mendezine symbol "Mz, is -2. What is the chemical formula for the compound called lindenium mendezide?

Answers

Answer:

Ld₂Mz

General Formulas and Concepts:

Chemistry - Compounds

Valence shells
Writing chemical compounds
Balancing charges

Explanation:

Step 1: Define

"Lindenium" Ld w/ oxidation charge of +1

"Mendezine" Mz w/ oxidation charge of -2

Step 2: Write Compound

To balance out the charges to be neutral (0), we must counter balance the amount of Ld's with Mz's. We need 2 Ld's with 1 Mz to create a compound with a neutral charge:

2Ld¹⁺ + Mz²⁻

2(+1) + (-2) = (+2) + (-2) = 0 (neutral charge)

Therefore, our compound must be Ld₂Mz.

Answer: The elements which are common for all organic molecules is hydrogen and carbon.

Explanation:

Another name for organic molecules are hydrocarbons. This means that the molecules which consist of hydrogen and carbon atoms is an organic compound.

For Example:

$H_2O\text{ and }CO_2$ are not organic compounds, because in water, carbon is not there and in carbon dioxide, hydrogen is not there. But, $CH_4$ is an organic compound because hydrogen and carbon both are present.

Hence, hydrogen and carbon elements are common to all organic molecules.
