Hydrogen and carbon atoms

Explanation:

Hydrocarbons are molecules that are made up of hydrogen and carbon atoms only.

They are made up of covalent bonds between the carbon and hydrogen atoms.

There is a wide range of hydrocarbons due to the unique properties of carbon.

Most of the hydrocarbons comes from crude oil, natural gas and coal.

When hydrocarbons burn, they produce water and carbon dioxide alone.

They are used as fuel in industrial processes because they produce heat energy.

How many grams of aluminum metal can be produced when 50.0 grams of aluminum chloride decompose? 2AlCl3 → 2Al + 3Cl2
Arisa [49]

Answer:

10.1 g of Al are formed

Explanation:

The reaction is:

2AlCl3 --> 2Al + 3Cl2

So 2 moles of aluminun chloride decompose into 2 moles of Al and 3 moles of chlorine.

Ratio is 2:2.

Let's convert the mass of salt into moles (mass / molar mass)

50 g / 133.34 g/mol = 0.374 moles.

As the ratio is 2: 2, if I have 0.374 moles of salt, I would produce the same amount of Al, just 0.374.

Let's convert the moles to mass

(Mol . molar mass)

0.374 mol . 26.98 g / mol = 10.1 g of Al are formed

Differentiate between speed and velocity
Leokris [45]

Explanation:

Speed and velocity are both used to describe the motion of a body. But there are differences between the two terms.

  • Velocity is the rate of change of displacement with time. It is mathematically expressed below:

                      Velocity = \frac{displacement}{time taken}

 The unit of velocity is m/s or km/hr.

Velocity is a vector quantity that shows magnitude and direction.

  • Speed is the rate of change of distance with time. It is concerned with the total length of path a body moves.

                  Speed = \frac{Distance }{time taken}

  It has the same unit as velocity

It is a scalar quantity that has only magnitude.
