Answer:

B a shared pair of electrons (2)

Explanation:

In Lewis structures, a single line represents a single pair of electrons. This means that the elements share 2 electrons or one pair of electrons

Hope this helps!

Which of these statements describes this mathematical equation?
salantis [7]

Answer:

The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature

Explanation:

Given

\frac{P_1V_1}{T_1} = k

Required

Interpret

\frac{P_1V_1}{T_1} = k

Multiply both sides by T1

T_1 * \frac{P_1V_1}{T_1} = k * T_1

P_1V_1 = kT_1

Divide both sides by V1

\frac{P_1V_1}{V_1} = \frac{kT_1}{V_1}

P_1 = \frac{kT_1}{V_1}

This can be rewritten as:

P_1 = k\frac{T_1}{V_1}

In the above expression; k is a constant of proportionality.

So, the equation can be written as variation as follows:

P_1\ \alpha\ \ \frac{T_1}{V_1}

To interpret:

<em>P varies directly to T (the numerator) and inversely to V (the denominator).</em>

Select the correct statement (2.5 Points) (A) s-orbitals are spherical in shape. (B) P-orbitals are dumbbell in shape. (C) s-orb
Lilit [14]

Answer:

The correct option is: (D) All of the above

Explanation:

An atomic orbital is the three-dimensional space or region around the nucleus of an atom, where the probability of finding an electron is maximum.

The s-orbitals are the atomic orbitals that have azimuthal quantum number, l = 0. These atomic orbitals have <u>spherical shape and symmetry.</u>

The p-orbitals are the atomic orbitals that have azimuthal quantum number, l = 1. These atomic orbitals have a <u>dumbbell shape.</u>

The atomic orbitals that are closer to the nucleus, have lower energy. Therefore, we can say that the <u>s-orbitals are lower in energy than the p-orbitals.</u>
