Transcript

The Universe is made of matter. 98% of this matter (ignoring the dark matter) is pure Hydrogen and Helium, but thankfully billions of years ago supergiant stars fused the hydrogen and helium into all the other elements and then exploded them all over the Universe and that’s where chemistry came from. These elements grouped together into a vast arra... Read More

Questions & Answers

Q: What is the relationship between atoms and molecules?

Atoms are the building blocks of matter, and when they combine, they form molecules. Molecules can have different properties than their individual atoms.

Q: How does energy influence chemical reactions?

Energy determines when reactions will occur and can be used to speed up or initiate reactions. It also influences the phase of matter (solid, liquid, or gas) that a substance exists in.

Q: What are the different types of chemical reactions?

Chemical reactions can be categorized into oxidation-reduction reactions (transfer of electrons), acid-base reactions (transfer of hydrogen ions), and equilibrium reactions (where the amounts of substances remain constant).

Q: How do analytical chemists determine the composition of a sample?

Analytical chemists use various techniques like spectroscopy and mass spectrometry to probe and measure different properties of materials, helping determine their composition and quantities.
