Answer:

Isotopes

Explanation:

Isotopes are the same element with different masses because of the different number of neutrons. Also, the element doesn't change. If we change the protons, the element will change and then it won't be an isotope. Hope it helps!

6.0 L of gas in a piston at a pressure of 1.0 atm are compressed until the volume
alex41 [277]

Answer:

1.71atm

Explanation:

The following were obtained from the question:

V1 (initial volume) = 6L

P1 (initial pressure) = 1atm

V2 (final volume) = 3.5L

P2 (final pressure) =?

Using the Boyle's law equation:

P1V1 = P2V2, the final pressure can be obtained as follow:

P1V1 = P2V2

1 x 6 = P2 x 3.5

Divide both side by 3.5

P2 = 6/3.5

P2 = 1.71atm

The final i.e the new pressure inside the piston is 1.71atm

A chemical change is a change in the ______ of a substance.
max2010maxim [7]
Alterations to the electron-based ionic or covalent bonds between ions or atoms happen during a chemical change. Such changes result in one or more new substances with different physical and chemical properties. This type of change stands in contrast to physical changes which, despite sometimes closely resembling chemical changes, only produce a change in physical properties.
