2[H⁺] + [O²⁻] → H₂O

Explanation:

Half reactions are usually composed of components of oxidation-reduction (redox) reaction where one element is losing electrons while another is gaining so they can come together into a compound. The half-reaction shows part of a reaction where the combining elements are charged and the product, from the redox, is neutral.

In this case, the H⁺ is carrying the positive charge because it is donating an electron to O²⁻, which is the reason the O²⁻ is carrying the negative charge. Note that we need 2 H⁺ for every one O²⁻.  The O is being reduced while the H is being oxidized.

Electron orbitals or shells are also called and abbreviated as?​
umka21 [38]

Answer:

An Orbital is best described as the volume of space in which electrons are most often found

Explanation:

As we know atom consists of sub-particles commonly known as protons, neutrons and electrons. The outer space around the nucleus where the probability of finding electrons is maximum is known as orbital. As the electrons are not precisely ordered around the nucleus hence it is not easy to tell the exact position of an electron.

                Hence, four quantum numbers are used to locate the position of electrons around the nucleus.

  i) Principle Quantum Number:

                                                   This number explains the main energy level which tend to increase in energy as the distance of electrons from nucleus are increased. Principle Quantum Numbers are integer number ranging from one to infinity. Hence, increase in this quantum number results in increase of the size of orbital.

  ii) Azimuthal Quantum Number:

                                                     This Quantum Number explains the direction of particular orbital in 3-dimensional space. Also it is responsible for the shape of an orbital.

 iii) Magnetic Quantum Number:

                                                      This Quantum Number also tells the direction of orbital in 3D space with respect to x, y and z axis.

 iv) Spin Quantum Number:

                                              This Quantum Number tells about the spin direction of an electron about its axis which may be clockwise or anticlockwise.

Which diagram represents an electrically neutral atom​?
Rom4ik [11]

Answer:

D

Explanation:

I hope this right, I'm sorry if it's not.

For an atom to be neutral, it has to have the same amount of protons and electrons. Because protons and electrons have opposite charges, when there is an equal amount of them they balance each other out

Hydrogen gas is collected over water at 21 degrees Celsius. At 21 degrees Celsius the vapor pressure of water is 18.7 torr. If t
Alinara [238K]

Answer : The pressure of hydrogen gas is, 739.3 torr

Explanation :

As we are given:

Vapor pressure of water = 18.7 torr

Barometric pressure = 758 torr

Now we have to calculate the pressure of hydrogen gas.

Pressure of hydrogen gas = Barometric pressure - Vapor pressure of water

Pressure of hydrogen gas = 758 torr - 18.7 torr

Pressure of hydrogen gas = 739.3 torr

Therefore, the pressure of hydrogen gas is, 739.3 torr
