Velocity is the slope of the acceleration vs. time graph.OA. TrueFalse​

Chemistry
1 answer:
Maurinko [17]3 years ago
7 0

Answer:

False

Explanation:

The slope of a velocity-time graph gives acceleration. Acceleration can be defined as the change in velocity with time.

A slope denotes the gradient of line. It takes into consideration the changes on both y and x axis. The ratio of the changes gives the slope.

On a velocity-time graph, the y-axis is the velocity and the x-axis is time. The change in velocity with time gives acceleration.

The slope of an acceleration

-time graph is not velocity.

nasty-shy [4]

surrounds the nucleus of an atom in various energy levels called orbitals.

Explanation:

Electrons surrounds the nucleus of an atom in various energy levels called orbitals.

According to the Bohr's model of an atom, the extra nuclear space is made up of electrons in specific spherical orbits called shells or energy levels.

  • The region of a maximum probability of where an electron is located is sometimes referred to as an electron cloud or orbital.
  • Electrons move round the nucleus in certain permissible orbits.
  • An electron in an energy level posses a definite amount of energy associated with it at that level.
  • Electrons moves through the energy levels by gaining or losing energy.

Thomas poured 25 mL of 0.60 M HCl into a large bottle. He then added enough water so that the new (diluted) concentration was 0.
Molodets [167]

Answer:

The answer to your question is 150 ml

Explanation:

Data

Volume 1 = 25 ml

Concentration 1 = 0.6 M

Volume 2 = ?

Concentration 2 = 0.1 M

Formula

            Volume 1 x Concentration 1 = Volume 2 x Concentration 2

Solve for Volume 2

             Volume 2 = (Volume 1 x Concentration 1)/Concentration 2

Substitution

             Volume 2 = (25 x 0.6) / 0.1

Simplification

            Volume 2 = 15 / 0.1

Result

            Volume 2 = 150 ml
