How many atoms are in this iron nail?

Chemistry
1 answer:
Lorico [155]3 years ago
3 0

Answer:

The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains 6.022 X 1023 atoms, regardless of the type of element.

Iron (Fe) has an atomic mass of 55.845 g/mol. So if you have 13.2 grams, you have 13.2/55.845 mol = 0.2364 moles.

Hope this helps!

Some chemical reactions that are reversible (put some picture for better understanding)
GalinKa [24]

Ammonium chloride is a white solid that breaks down when heated and produces ammonia and hydrogen chloride.

<h3>What is the reversible reaction?</h3>

A reversible reaction is a reaction in which the conversion of reactants to products and products to reactants occur at the same time. In the above example, the chemical shows a reversible reaction because it moves both forward and backward direction. In reversible reaction, equal amount of reactant is converted into product and product into reactant.

So we can conclude that Ammonium chloride is a chemical that represents a reversible reaction.

Consider the following chemical reaction: CO (g) + 2H2(g) ↔ CH3OH(g) At equilibrium in a particular experiment, the concentratio
AlexFokin [52]

Answer:

The equilibrium concentration of CH₃OH is 0.28 M

Explanation:

For the reaction: CO (g) + 2H₂(g) ↔ CH₃OH(g)

The equilibrium constant (Keq) is given for the following expresion:

Keq= \frac{(CH3OH)}{(CO) x (H2)^{2}} =14.5

Where (CH3OH), (CO) and (H2) are the molar concentrations of each product or reactant.

We have:

(CH3OH)= ?

(CO)= 0.15 M

(H2)= 0.36 M

So, we only have to replace the concentrations in the equilibrium constant expression to obtain the missing concentration we need:

14.5= \frac{(CH_{3}OH) }{(0.15 M) x (0.36 M) ^{2} }

14.5 x (0.15 M) x (0.36)^{2} = (CH₃OH)

0.2818 M = (CH₃OH)

Boron has two naturally occurring isotopes; B-10 with a mass of 10.01 amu and a natural abundance of 20.00%, and B-11 with a mas
balandron [24]

Atomic mass of boron = 10.81

<h3>What are Isotopes?</h3>

Isotopes are variants of a particular element in which they have the same number of protons but differ in the number of neutrons in the atom.

So, here as we said we have isotopes which weigh 10.01 and 11.01.

Given,

relative abundance of B-10 = 10.1 amu

relative abundance of B- 11 = 11.01 amu

percentage of B-10 = 20%

percentage of B-11 = 80%

Then the relative atomic mass depends upon the relative abundance of various isotopes of that particular element. Suppose an element consists of two isotopes and average atomic mass is equal to

(Relativeabundance(1)×Atomicmass(1)+Relativeabundance(2)×Atomicmass(2)) / (Relativeabundance(1)+Relativeabundance(2))

Atomic mass of boron = (20 × 10.01 + 80 × 11.01) / (80 + 20 )

= 1081/100

= 10.81
