What happens in the artificial transmutation of an element? Include an example.

1 answer:

6 0

What happens in the artificial transmutation is that the nucleous is bombarded with high energy particles which we can describe as kinetic energy and the idea for them is to induce what we call transmutation. Also what happens is that the high energy particles are accelerated. One of the examples is when nitrogen is transformed into hydrogen by combining its nucleous with an alpha particle

A balloon filled with helium occupies 20.0 l at 1.50 atm and 25.0◦c. How many moles of helium will there be in the balloon at st

satela [25.4K]

Answer:

There will be 1.23 moles of helium in the balloon at STP

Explanation:

1) Initial conditions of the helium gas:

V = 20.0 liter
p = 1.50 atm
T = 25.0 °C = 25.0 + 273.15 K = 298.15 K

2) Ideal gas equation:

pV = n RT
p, V, and T are given above
R is the Universal constant = 0.0821 atm-liter / ( K - mol)
n is the unknown number of moles

3) Solve for n:

n = pV / (RT) =

n = 1.50 atm × 20.0 liter / (0.0821 atm-liter /k -mol ×298.15K)

n = 1.23 mol

4) At STP:

STP stands for standard pressure and temperature.

The amount (number of moles) of the gas will not change because the change of pressure and temperature, so the number of moles reamain the same: 1.23 mol.

Which of the following can be found in an atom's nucleus?

slamgirl [31]

D. protons

AND NEUTRONS

The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds.
