The answer is (c.) There is a dense, positively charged mass in the center of an atom
In 1899, Ernest Rutherford, a British physicist conducted a study of the absorption of radioactivity by thin sheets of metal foil. On this experiment, he concluded that all the positive charge and the mass of the atom is concentrated in a small fraction of the total volume of the atom which is called the Nucleus.

marin [14]

Answer:

The answer to your question is Pressure = 5 atm

Explanation:

Data

Volume 1 = V1 = 0.5 l

Pressure 1 = P1 = 1 atm

Volume 2 = V2 = 0.1 l

Pressure 2 = P2 = x

Formula

To solve this problem use the Boyle's equation

                      V1P1 = V2P2

Solve for P2

                     P2 = V1P1/V2

Substitution

                     P2 = (0.5 x 1) / 0.1

Simplification

                     P2 = 0.5/0.1

Result

                     P2 = 5 atm

A helium balloon has a volume of 735 mL when it is at ground level. The balloon is
bagirrra123 [75]

Answer:

The answer to your question is P1 = 1.4 atm

Explanation:

Data

Volume 1 = V1 = 735 ml

Pressure 1 = P1 = ?

Volume 2 = V2 = 1286 ml

Pressure 2 = P2 = 0.8 atm

Process

To solve this problem use Boyle's law.

          P1V1 = P2V2

-Solve for P1

          P1 = P2V2 / V1

-Substitution

          P1 = (0.8 x 1286) / 735

-Simplification

          P1 = 1028.8 / 735

-Result

          P1 = 1.4 atm
