In the world of chemistry a mole is a number of something a very large number of something.Just as a dozen is 12 of something a mole is about 6.02*10^23 of something.In chemistry we like the number of atoms or molecules in moles.If one mole is equal to 6.02*10^23 atoms and you have 9.00 *10^23 atoms then how many moles do you have?
B.the energy of the products
c.the energy of activated complex
d.the energy of activation
Answers
The correct answer is D. The energy needed for a chemical reaction is called the activation energy. This energy is to be present in order for the reaction to happen. This can be achieved by supplying or releasing heat from a system of reactants. This can achieved faster by using a catalyst.

The molarity of the HCl acid is 0.480 M. The correct option is 2.
What is molarity?
Molarity is the division of the mass of the solution to the volume of the solution.
The formula that is used is
Putting the values in the equation
0.620 * 12.7 = M1 * 16.4 = 0.480
Thus, the molarity of the HCl acid is 2). 0.480 M.

Molarity is equal to the moles of solute over liters of solvent. In getting the molarity of HCl, you must know the formula for two solutions which is equal to M1V1 = M2V2. (16.4 milliliters of HCl)M1 = (12.7 milliliters) (0.620 M KOH) and you have 0.480M HCl. The answer is number 2.

Iron rust is the oxidation process that affects iron. Iron reacting with oxygen loses three electrons to form rust. Thus, option b is accurate.
What are oxidation and reduction?
Oxidation is the redox process that raises the oxidationnumber by losing the electron of the species and the reduction will decrease the oxidation state by accepting the electrons.
The iron loses its three electrons when reacts with the atmospheric oxygen in rusting and gets oxidized. The metal oxide is produced as a result of the rust.
Therefore, option b. losing threeelectrons to produce rust is correct.

Answers
Option C - Electrons are outside the nucleus and and have a negative charge is the correct alternative.
We have electrons.
We have to determine their role inside the atom.
What are Electrons ?
An electron is one of the subatomic particles within an atom. It is negatively charged particle whose magnitude is 1.6 x 10⁻¹⁹ C.
According to the question -
The role of electrons inside the atom is as follows -
- Electrons revolve around the nucleus.
- They carry a negative - charge of -1.6 x 10⁻¹⁹ C.
Hence, Option C is the correct alternative.
