Answer:

Formic acid, citric acid, Oxalic acid, washing soda, baking soda, etc. can be some examples of natural acids and natural bases. They both have domestic, industrial, and various other purposes.

Explanation:

<h3><u>NATURAL ACIDS</u>:</h3>

There are lots of natural acids present in our nature. Some of them are the following:

> <u>Formic acid</u>

 USE: It is used in the stimulation of oil and gas wells as it is less reactive towards the metal.

> <u>Citric acid</u>

 USE: It is considered as the best rust remover as it doesn't harm the metal just remove the rust.

> <u>Oxalic acid</u>

USE: It easily remove iron and ink stains and that's why it is used as an acid rinsing material in Laundries.

<h3><u>NATURAL BASES</u>:</h3>

There is a variety of natural base found in our nature which founds a lot of uses in day to day life. some of them are the following:

> <u>Washing soda</u>

USE: It is used in commercial detergent mixture to treat hard water.

> <u>Baking soda</u>

USE: It is the best rising agent used mostly in cooking and for domestic purposes like removing stains, etc..

Can you describe the situations when Greek prefixes are used?
Black_prince [1.1K]

Answer:

Here's what I get  

Explanation:

At the introductory level of chemistry, I can think of only two situations when you use Greek prefixes.

They indicate the number of atoms or groups in a molecule when you are naming a compound.

1. Binary covalent compounds

For example, P₂S₅ is diphosphorus pentasulfide.

2. Hydrates

For example, Na₂SO₄·10H₂O is sodium sulfate decahydrate.

An ion of iron has an 26 protons, 30 neutrons, and 23 electrons. what are its atomic number, atomic mass, and net charge?
Murrr4er [49]

Answer:

Z=26, A = 56, charge +3.

Explanation:

The atomic number is represented by Z. Is equal to the total number of protons that the atom has.  Z=26.

The atomic mass is represented by A. The number results from the total sum of protons and neutrons of an atom.  Both particles have a weight of 1 uma, are in the nucleus and give the mass to the atom.

Mass number (A) = atomic number (Z) + number of neutrons (N)

                        A = 26 + 30

                        A = 56

The net charge of the atom can be calculated by subtracting the negative charges from the positive ones. The positive charges come from the protons and the negative ones from the electrons.

26-23=3

This iron ion has a positive charge +3.
