The correct answers are:

The objects speed

The objects direction

The objects velocity.

When an object is accelerating the mass of the object wouldn't be effected by it's moving.

Three quantum numbers are derived from Schrodinger’s equation that describe the probability of finding an electron around a nucl

hodyreva [135]

Principle: Orbital size & main energy level

Angular: Orbital shape

Magnetic: Orbital orientation

Orbital size is Principle; main energy level is Principle; shape is Angular; orientation is Magnetic

Principle:

imagine a bullseye. each ring shows how far its from the nucleus

Angular:

0 looks like circle

1 looks like a bowtie

2 looks like a flower or 4 leaf clover

3 looks like multiple lobes

Principle Quantum Number: It describes the size of the orbital and the main energy level. It is represented by n. Where, n = 1,2,3,4....stands for K, L, M, N shell and so on..

Angular momentum Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from . When l = 2, the value of will be -2, -1, 0, +1, +2.

If 0.500 mol of NaN3 react what mass I'm grams of nitrogen would result

klemol [59]

Looks like 3*.5 mol of N, or 1.5*.5 N2
convert that to grams.

In modern atomic theory, bohr's orbits are replaced by atomic orbitals. what is an atomic orbital?

Darya [45]

Bohr's theory states that the motion of the electron (particle) around the nucleus is very much similar to motion of the planets around the sun in the solar system. Both in the mathematical and physical sense.

The Bohr's Atomic theory only explains the motion of the electrons in discrete atomic orbitals that are predicted by the Bohr's equation.

It strictly implies that the electron only exists in these discreet orbitals and fails to explain anything about the nature of the electron in between the discrete orbitals.

The modern atomic theory does not share this limitation as it does not impose the electron to only occupy the discrete orbitals and neither does it impose particle nature upon the electron.

In the modern theory does not focus on describing the motion of the electron around the orbital but rather the probability of finding an electron around the nucleus. The modern atomic orbitals or electron clouds are the regions in which the probability of finding the electron is the highest when the wave function collapses. The Schrödinger's wave equation explains the evolution of the wave function in time. Hence enabling us to predict the future possible locations of the electron but never the exact location as that is impossible due to the Heisenberg's Uncertainty principle.

Calculate the molarity of 3.00 moles of KCL dissolved in 2.00L of solution.

skad [1K]

Answer:

1.5 Molar solution in KCl

Explanation:

Definition of molarity => moles of solute / Volume of solution in Liters

Given 3.00 moles of solute dissolved in 2Liters of solution

Molarity of [KCl] = 3.00 moles KCl / 2Liters solution = 1.5 Molar solution in KCl

In the fusion reaction occurring in the Sun, how does the mass of helium atom formed compare to the mass of the hydrogen atoms?

sladkih [1.3K]

The nuclear fusion in our sun combines two hydrogen atoms (the smallest and lightest atoms) together to form one helium atom (a slightly larger atom). During the process some of the mass is converted into energy.
