The combustion of magnesium creates so much energy so quickly that it is hard to measure its enthalpy directly using a simple ca

Answer: Rearrange the lone pairs of electrons from the outer atom(s) to create double or triple bonds with the central atom.

Explanation:

Result: 1.68 L of liquid nitrogen is generated during the gas liquefaction process.

Clarification:

This process involves transforming gaseous nitrogen into its liquid form.

The two states possess distinct densities, thus occupying varying volumes; however, the mass remains constant.

Step 1: Calculate the mass of nitrogen gas

Let’s determine the mass of nitrogen gas associated with 297 L.

The density formula is:

With a density of nitrogen gas at 4.566 g/L and a volume of 297 L, we can compute the mass of nitrogen gas as follows:

Using these values yields:

The mass of nitrogen gas calculates to be 1356 g.

Step 2: Derive the volume of liquid nitrogen from the mass obtained

The mass for liquid nitrogen remains the same.

With the density of liquid nitrogen at 809 g/L, we can substitute this into our formula to find the volume of liquid.

Therefore, the volume of liquid nitrogen is 1.68 L.

Answer:

Explanation:

Oxidation:

Oxidation refers to the process where electrons are lost, resulting in an increase in the oxidation state of an atom of an element.

Reduction:

Reduction is characterized by the acquisition of electrons, leading to a decrease in the oxidation number.

Oxidizing agents:

Oxidizing agents facilitate oxidation of other substances while they themselves undergo reduction.

Reducing agents:

Reducing agents cause the other element to be reduced, while they are oxidized in the process.

Examine the following reaction:

2AgCl + Zn  → 2Ag + ZnCl₂

In this instance, the oxidation state of Zn on the left is 0 and rises to +2 on the right, indicating it is oxidized, while the oxidation state of Ag drops from +1 on the left to 0 on the right, showing it is reduced.

4NH₃  +  3O₂   →   2N₂ +  6H₂O

For this reaction, nitrogen's oxidation state shifts from -3 on the left to 0 on the right, signifying it is oxidized, whereas oxygen decreases from 0 to -2, indicating it gets reduced.

Fe₂O₃ +  2Al  →   Al₂O₃ +  2Fe

Here, the oxidation state of iron reduces from +3 on the left to 0 on the right, meaning it is reduced, while aluminum shifts from 0 to +3, indicating it is oxidized.

Answer:

The ratios arranged in ascending order are; The ratio of the mass of Y to X in XY2 divided by the mass of Y to X in XY, The ratio of the mass of Y to X in XY3 divided by the mass of Y to X in XY, The ratio of the mass of Y to X in XY4 divided by the mass of Y to X in XY

1) Mass ratio = 3

2) Mass ratio = 2

3) Mass ratio = 4
