why Sodium and phosphorus are in the same period, but they have different atomic radii?

Answers

Answer 1

Answer:

Because sodium is on the left side of the PT and phosporus is on the right side. And atomis radius decreases from left to right.

Explanation:

how do humans benefit from photosynthesis

Answers

Equally importantly, photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere. Oxygen is required for cellular respiration, the process by which food is broken down into energy. Thus, human beings are also solely dependent on photosynthetic plants for their oxygen requirements.

Answer:

Explanation:

Without photosynthesis there would be no oxygen in the earth's atmosphere and we wouldn't be here!

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 shellsWriting chemical compoundsBalancing 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.

Reaction type
Li + N2
Li3N

Answers

Answer:

Combination or synthesis

Explanation:

The given reaction is:

6Li + N₂ → 2 Li₃N

This reaction is a synthesis or combination reaction. 6 moles of Li combines with nitrogen gas to produce 2 moles of Li₃N.

In a synthesis reaction, two substances combines together to give singular product. The formation of compounds from the union of the constituent elements falls into this category of reaction.

A scientist thinks he found a new metal, so he published a paper about this metal. About 1 week after the scientist published the paper, you noticed a problem with the paper the scientist wrote. You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered. Using the techniques from Chemistry, you ran a Flame Test with a piece of the metal (the metal is safe to use) that you had shipped to you. You found the metal turned the flame yellow. What metal did you have in your possession?

Answers

Answer:

[tex]Mass = 102g[/tex]

Explanation:

Given

Compound: [tex]Al_2O_3[/tex]

Required

Determine the equivalent mass

In the above compound, we have: 2 Al and 3 (O)

The atomic mass of Aluminium is:

[tex]Al = 27[/tex]

The atomic mass of Oxygen is:

[tex](O) = 16[/tex]

So, the equivalent mass is:

[tex]Mass = 2 * 27 + 3 * 16[/tex]

[tex]Mass = 54 + 48[/tex]

[tex]Mass = 102g[/tex]

Choose two different particles found in the air. Explain how they are different and how they are the same

Answers

Answer:

Dust and smoke.

Explanation:

Dust and smoke are two different particles present in the air. Dust and smoke are different from one another due to their origin. Smoke formed from burning of materials while dust refers to the soil particles lifted by the wind due to their light weight. Dust and smoke are similar to each other due to their small in size, infinite number means uncountable and light weight.

Air is a mixture of gases and consists of dust particles and water vapor. It consists of small to very large size of particles. Some of them include dust pollen, soot, and liquid droplets.

Dust and soot particles of the air are different as the soot is a fine black particle of carbon and tar. It is made by the incomplete combustion of air. While dust is fine dry particles of matter.

Hence they both differ.

Answers

I think the answer is an element

The sample here is a compound. The correct option is c.

What is a compound?

A chemical compound is a substance made up of many identical molecules that contain atoms from more than one chemical element and are held together by chemical bonds.

A molecule made up of only one element's atoms is thus not a compound.

The anode undergoes oxidation, while the cathode undergoes reduction. The species being oxidized provides the electrons.

An electrode in an electrochemical cell is referred to as an anode or a cathode depending on the direction of electron flow.

The electrode reacts with the electrolyte at the anode, producing electrons.

These electrons build up at the anode. Meanwhile, another chemical reaction occurs at the cathode, allowing that electrode to accept electrons.

Thus, the correct option is c.
