What is the general term used for the following elements sodium 23 sodium 24 and sodium 31?​

Chemistry
1 answer:
vivado [14]3 years ago

Answer:

Isotopes.

Explanation:

Hello,

In this case, in chemistry, we defined isotopes as those atoms of the same element that eventually have the same amount of protons and electrons but different specific atomic masses which is also related with different amount of neutrons among atoms, that is why the atomic mass of an element corresponds to the average atomic mass of each isotope composing it.

Commonly, those isotopes are represented via the name of the element followed by its atomic mass, for instance carbon-14 which is widely used for dating. In such a way, for sodium-23, sodium-24 and sodium-31, we talk about the isotopes of sodium.

Best regards.

SCIENCE, PLEASE HELP.
sesenic [268]

Answer: B

Explanation:

protons are positive,

electrons are negative,

and neutrons are neutral.

the amount of electrons to protons is always the same in a balanced atom.

electrons can be removed creating "ions" which is simply an unbalanced atom. removing protons would result in a different type of atom or element.

Keq for the reaction below is 2400. If the initial conditions of the reaction are a 1.0 L flask that contains 0.024 mol NO (g),
podryga [215]

Answer:

The answer to your question is it is not at equilibrium, it will move to the products.

Explanation:

Data

Keq = 2400

Volume = 1 L

moles of NO = 0.024

moles of N₂ = 2

moles of O₂ = 2.6

Process

1.- Determine the concentration of reactants and products

[NO] = 0.024 / 1 = 0.024

[N₂] = 2/1 = 2

[O₂] = 2.6/ 1= 2.6

2.- Balanced chemical reaction

                     N₂ + O₂    ⇒   2NO

3.- Write the equation for the equilibrium of this reaction

                     Keq = [NO]²/[N₂][O₂]

- Substitution

                    Keq = [0.024]² / [2][2.6]

-Simplification

                    Keq = 0.000576 / 5.2

-Result

                    Keq = 1.11 x 10⁻⁴

Conclusion

It is not at equilibrium, it will move to the products because the experimental Keq was lower than the Keq theoretical-

                         1.11 x 10⁻⁴ < 2400
