if an atom of carbon gains or loses a proton, what is it called?

When water is added to a compound in a chemical equation, a new compound can be formed via hydrolysis.

It refers to any chemical process when a water molecule breaks one or more chemical bonds. When water is the nucleophile, the phrase is used generically to refer to substitution, elimination, and solvation processes.

The cleavage of biomolecules known as biological hydrolysis occurs when a water molecule is consumed in order to cause the division of a bigger molecule into its component parts. Scarification is the process of hydrolyzing a carbohydrate into its individual sugar molecules, as occurs when sucrose is broken down into glucose and fructose.

A condensation reaction, in which two molecules combine to form a bigger one and expel a water molecule, can be reversed by a hydrolysis reaction. Thus, condensation builds up by removing water, but hydrolysis breaks down by adding water.

Explanation:

Answer: Mass number is 15

Explanation:

Mass number of an atom is the sum or total number of protons and neutrons present in the atom. It is represnted by the letter A

The Atomic number (Z) of an atom is defined as the number of protons in an atom and it is equal to the number of electrons present in the atom.

A= n + p

where n is the number of neutrons and p is the number of protons present in the atom

Z = p = e

Where p is the number of protons and e is the number of electrons present in the atom

Z for oxygen atom is 8

So, Z = p = 8 for oxygen atom

If n = 7

then A for oxygen atom with 7 neutrons is given by

A= n + p = 8+7 = 15.

Ions are any molecules that have a charge. (positive or negative.) Group 1 atoms have 1 valence electron, so their ions are formed by giving away one electron. Group 7 atoms have 7 valence electrons, so their ions are formed by gaining one electron. This process gives the atom a full shell of 8, which makes it stabilized.

To prepare 128.2ml of a 0.364 M aqueous solution of NaCl.the mass in grams, of NaCl need to use to make the solution is 2.723 gm.

Molarity is defined as the no. of moles of solute per liter of solution.

Here,

Molarity =  moles of solute / Liter of solution

0.36 M solution will contains 0.364 moles of NaCl.

therefore, volume of solution in L =  ( 128.2 / 1000 ) L × 1 L

that means, it will contain, no. of moles of NaCl

= (0.1282 L of solution × 0.364 ) / 1 L of solution      

= 0.0466 moles of NaCl

now, molar mass of NaCl  = 58.44 g/mol    

so, 1 mol of NaCl has a mass of  58.44 g/mol

therefore, 0.0466 moles of NaCl will have mass of

= ( 0.0466 moles of NaCl × 58.44 g ) / 1 mole of NaCl

= 2.723 g

The difference between ideal gases and real gases are most pronounced under conditions of inter molecular forces.

Difference between ideal gases and real gases are discussed below :

Real gases differ from ideal gases thanks to the presence of inter molecular forces, which cause the molecules of a true gas to deviate from perfect random motion.

As a result, real gases deviate from the perfect gas law at high densities and low temperatures, where the results of inter molecular forces are more pronounced.

So, the difference between ideal gases and real gases are most pronounced under conditions of inter molecular forces.

What are inter molecular forces?

The attractive forces that exist between molecules are liable for many of the bulk physical properties exhibited by substances.An inter molecular force (IMF) (or secondary force) is that the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion which act between atoms and other sorts of neighboring particles, e.g. atoms or ions.

Answer:

First, I will convert from grams to moles. This will give me approximately 4.032 moles of carbon, 6.740 moles of hydrogen, and 3.344 moles of oxygen. Then, I will calculate the mole ratio, using whole numbers. I must also identify the least amount of moles in an element for this step, which is oxygen at 3.344 moles.

Oxygen = 3.344/3.344 = 1

Carbon = 4.032/3.344 = 1

Hydrogen = 6.740/3.344 = 2

The empirical formula will be COH2.

Now that we have the molar mass of the molecular formula, we can calculate for the molecular formula. First, we will begin by discovering the molar mass of the empirical formula, which will be C molar mass x 1 + O molar mass x 1 + H molar mass x 2. That will be equal to 60.949. After that, we can divide the molecular mass by the empirical formula molar mass, giving us approximately 3. Now we will multiply the empirical formula by 3, giving us our molecular formula, which will be equal to C3O3H6.

Analytical chemist analyses show that a sample of acetic acid contains 2.4 moles of carbon. The number of moles of hydrogen in the sample is 5.75 moles.

The mole is a SI unit of measurement that is used to calculate the quantity of any substance. Mole can be calculated by dividing the mass by the molar mass.

Acetic acid is a colorless liquid, with a pungent smell.

The formula of acetic acid is CH₃COOH

For every 12 moles of hydrogen, there's 1 mole of oxygen.

2.4 / 12 = 0.2.

If 25.0 ml is taken from a stock solution and added to volumetric flask and diluted up to the calibration mark, then the new concentration will be 1.49 g/L.

Now, Concentration of solution is defined as amount of solute present in specific volume of the solution.

Molarity (M) = moles of solute ÷ litres of solution

Here, the concentration of solution is given as, 14.9 g/l

and, the volume of solution is 25.0 ml= 0.025 l

using the equation,

   14.9 = moles of solute ÷0.025

   moles of solute = 0.3725 moles

0.025 l is added to a 0.25 l (250.0 ml =0.25 l) volumetric flask and diluted up to the calibration mark.

Since,

volume of solution = volume of flask
