The reaction equation is the chemical formula of reactants and products

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reactants and products

Reaction

Explanation:

Number of atoms : 2.245 x 10²⁴

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

n= 3.73 moles

Number of atoms :

[tex]\tt 3.73\times 6.02\times 10^{23}=\boxed{\bold{2.245\times 10^{24}}}[/tex]

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question we have

We have the final answer as

The substance will float on water since it's density is less than that of water which is

1 g/cm³.

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

. The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

How to add the number in scientific notation with same exponent.

7.21 ×10⁻³ + 2.11 ×10⁻³

exponent of both values are same thus we will take it common.

The work by Mark : 100 J

Work is the transfer of energy caused by the force acting on a moving object  

Work is the product of force with the displacement of objects.  

Can be formulated  

[tex]\tt W=F\times d[/tex]

W = Work, J, Nm  

F = Force, N  

d = distance, m  

Mark is using 5N to push the box 20 m,

F = 5 N

d = 20 m

[tex]\tt W=5\times 20\\\\W=100~J[/tex]
