Answer:
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
The mass of pure acetic acid in 220 ml of the given solution at 20°C is 92.311 g
<h3>What is Acetic acid?</h3>
Acetic acid is a type of carboxylic acid and also known as ethanoic acid
Its formula is CH₃COOH.
It is an organic compound and is a colorless liquid
It is mostly used in the production of vinegar
40 % acetic acid by mass means,
40 g of acetic acid is dissolved in 100 g of solution.
The density of solution at 20°C,

We know,


The volume of the solution,
= 95.33 ml
95.33 ml of solution contains 40 g of pure Acetic acid
220 ml of solution contains
= 92.311 g of pure Acetic acid
Thus, the mass of pure Acetic acid in 220 ml of solution at 20°C is 92.311 g

I think the answer would be b because your throat is reacting to the cough?
1. carbon dioxide is a gas at low temperatures at mars because in the oxidizing environment organic compounds are oxidized to form carbon dioxide.
2. The 1 electron in outermost shell of Na is shared with 7 electrons of outermost shell of chlorine giving neutral charge on compound.
3. Electrostatic force of attraction is between the metal and non-metal.
4. When metal and non metal exchange electrons to form a neutral or no charge compound it is said to have form ionic bonds.
Explanation:
1. Temperature at Mars is very low -80 Fahrenheit (-60 degrees) because water is not present in the planet. Carbon dioxide is abundant in Mars. The atmosphere is oxidizing at Mars which oxidizes the organic compounds and forms carbon dioxide.
2. NaCl combines by sharing of electrons forming ionic bonding. Different atoms of the different element share electrons to form ionic bonds. Such bond is formed when electrons is transferred between the atoms. In the NaCl, Na has 1 electron (electropositive) in its outer shell and chlorine has 7 electrons (electronegative). Both share the electrons getting their octet complete and a neutral charge on the compound formed.
3. Electrostatic force of attraction is between the metal and non-metal when bond is formed. The ionic bonds is formed between metal and non metals when electron exchange takes place. The electrostatic force is the attraction between two opposite charges on the ion.
4. When a metal and non metal exchange electrons in which metal is electropositive and non metal is electronegative the bonds form is called ionic bond. The electron is transferred from metal to non metal and thus giving neutral charge on the compound i.e. the outer shell has its octet complete.
