The mass of an electron is about 9.11 × 10-31 kg. Write this as a whole number

Answers

Answer:

1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?

(1 e)/(9.1 X 10-31 kg) = n/(1 kg)

So, n = 1.10 X 1030 electrons

Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C. This is an insane charge!

The electrostatic force between two of these 1kg bundles of electrons is given by Coulomb's law:

F = k qq/r2 = (8.99 X 109)(1.76 X 1011 C)2/(1000 m)2 = 2.78 X 1026 N.

Which is a substance that takes the shape and volume of its container?


gas

crystalline solid

amorphous solid

liquid

Answers

Answer:

liquid

Explanation:

Gases particles are located far apart from each other and they have no definite volume and shape. Gaseous substances takes the shape and volume of the container.

What are gases ?

There are three common states of matter namely, gas , liquid and solids. The particle composition in each state is different. In solids, the atoms or particles are tightly packed without a space to move them apart.

This strong intermolecular force in solids make them in perfect shape and size. They have definite volume also. In liquids, particles have some space to move apart and they can flow, so does no shape but have definite volume.

In the case of gaseous substances, the particles have least intermolecular forces and they are far apart and free to spread in the atmosphere. Hence, they don't have a definite shape and volume and they assume the shape and volume of the container.

Which is an example of a physical change?


salt dissolving

cake baking

gasoline combusting

iron rusting

Answers

answer :
b - cake baking

explanation :
because the rest of the options are changing due to chemical reactions , when you bake a cake your developing it’s actions by touching it physically
It would be salt dissolving because solubility is a physical change. If you were to boil salt that has dissolved in water you can get the salt back out of the water. Therefore, the chemical makeup of the salt is not being changed.
