Answer:

Explanation:

In general, an increase in pressure (decrease in volume) favors the net reaction  that decreases the total number of moles of gases, and a decrease in pressure (increase in volume) favors the net reaction that increases  the total number of moles of gases.

Δn= b - a

Δn=  moles of gaseous products - moles of gaseous reactants

Therefore, <u>after the increase in volume</u>:

  • If Δn= −1 ⇒ there are more moles of gaseous reactants than gaseous products. The equilibrium will be shifted towards the products, that is, from left to right, and K>Q.
  • If Δn= 0 ⇒ there is the same amount of gaseous moles, both in products and reactants. The system is at equilibrium and K=Q.
  • Δn= +1 ⇒ there are more moles of gaseous products than gaseous reactants. The equilibrium will be shifted towards the reactants, that is, from right to left, and K<Q.

How do you know the ph level of 10^-8
sergiy2304 [10]

pH=6.98

Explanation:

This is a very interesting question because it tests your understanding of what it means to have a dynamic equilibrium going on in solution.

As you know, pure water undergoes self-ionization to form hydronium ions, H3O+, and hydroxide anions, OH−.

2H2O(l]⇌H3O+(aq]+OH−(aq]→ very important!

At room temperature, the value of water's ionization constant, KW, is equal to 10−14. This means that you have

KW=[H3O+]⋅[OH−]=10−14

Since the concentrations of hydronium and hydroxide ions are equal for pure water, you will have

[H3O+]=√10−14=10−7M

The pH of pure water will thus be

pH=−log([H3O+])

pH=−log(10−7)=7

Now, let's assume that you're working with a 1.0-L solution of pure water and you add some 10

Based on the nature of the sub-atomic particles, the correct answers are:

5. No Charge

6. Negative

7. Neutrons and Protons

8. 35 electrons

9. atomic number is 5

10. atomic mass is 11

11. number of protons is 15

12. number of electrons is 20

13. number of neutrons is 30 (55 -25)

14. mass number is 7

15. number of neutrons is 11 (36 - 25)

<h3>What are the sub-atomic particles?</h3>

The sub-atomic particles are the electrons, protons, and neutrons.

The electron is negatively-charged, the proton is positively-charged, whereas, the neutron is neutral and has no charge.

The number of electrons in a neutral atom is equal to the number of protons.

The sum of protons and neutrons gives the mass number of the atom.

Considering the given questions:

5. What type of charge does a neutron have?

Answer = No Charge

6. What type of charge does an electron have?

Answer =  Negative

7. Which two subatomic particles are located in the nucleus of an

Answer = Neutrons and Protons

8. If an atom has 35 protons in the nucleus, how many electrons will it have orbiting the nucleus?

Answer = 35 electrons

9. What is the atomic number of the atom in the diagram above?

Answer = atomic number is 5

10. What is the atomic mass/mass number of the atom in the diagram above?

Answer = atomic mass is 11

11. How many protons are in the nucleus of an atom with an atomic number of 15?

Answer = number of protons is 15

12. How many electrons are in the nucleus of an atom with an atomic number of 20?

Answer = number of electrons is 20

13. How many neutrons are in the nucleus of an atom with an atomic number of 25?

Answer = number of neutrons is 30 (55 -25)

14. What is the mass number of an atom with 3 protons, 4 neutrons, and 3 electrons?

Answer = mass number is 7

15. How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25?

Answer = number of neutrons is 11 (36 - 25)

In conclusion, the mass number of an atom is the number of protons and neutrons in the nucleus of the an atom.
