Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

These clusters of strongly bonded atoms are called molecules. See how they're represented by two circles of different size and colour that are joined together. This particle diagram represents ...

It highlights that everything in the world is made up of atoms, which combine to form molecules. There are over 100 different types of atoms, and materials can be classified into elements ...

1. Convert kilograms/second to grams per second. 1 kg = 1000 grams. If the mass flowrate is 0.25 kilograms/second, convert this to 250 grams/second. 2. Convert grams to moles, using the molar mass of ...

NASA’s Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet. The ...
