Hydrogen has three isotopes. The most common one, protium, has no neutrons. Deuterium, the second isotope, has one neutron. Trit

ium has two neutrons. Using this information, calculate the atomic number, mass number, and no: of neutrons of these isotopes.

Atomic number is the number of protons in an atom. Since these are all Hydrogen, the number of protons remains the same, and the Atomic Number for each is 1. Mass number is the number of Protons and Neutrons in an atom. So, Protium is 1, Deuterium is 2, Tritium is 3. The number of neutrons is stated in the question (Protium 0, Deuterium 1, Tritium 2). Hope this helps, if you wouldn’t mind marking brandies if it did!

A balloon filled with 1.92 g of helium has a volume of 12.5 L. What is the balloon’s volume after 0.850 g of helium has leaked o
Marizza181 [45]

The answer is 1.56L. Avogadro's Law states that the volume of a gas is directly proportional to the number of moles (or a number of particles) of gas when the temperature and pressure are held constant.

V∝n

V₁/n₁m= V₂/n₂

V₁ = initial volume of gas  = 12.5 L

V₂ = final volume of gas = ?

n₁ = initial moles of gas  = 0.016 mole

n₂ = final moles of gas  = 0.016-0.007 = 0.002 mole

V₁/n₁m= V₂/n₂

V₂= 1.56L

Avogadro's Law is in evidence whenever you blow up a balloon. The volume of the balloon increases as you add moles of gas to the balloon by blowing it up.

Compare the three atom diagrams. which one shows the electron with the highest potential energy
lara31 [8.8K]

Answer : The one diagram which shows the electron with the highest potential energy is attached below.

Explanation : One can easily find the highest potential energy of the atom just by looking at the diagram, the electron which is from farthest distance from the atomic nucleus will have the highest potential energy in the electron.

can someone answer! please don't answer for points or if you don't know it and don't answer if you are guessing make sure you un
inessss [21]

Answer:

B

Explanation:

As the distance between the planets and the sun increases, the period of revolution increases as well. The period of revolution is how long it takes for a planet to revolve around the sun. So, because the planets farther from the sun have a higher period of revolution in earth years, this also means they have longer actual years, which means the answer is B.

What best describes the collision between ideal gas molecules
Alika [10]
An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces. One can visualize it as a collection of perfectly hard spheres which collide but which otherwise do not interact with each other.
