As we move across the period electrons occupy the same outer electron shell, having roughly the same distance to the nucleus. Moving across the period nuclear charge increases as the number of protons in ...

Part 1: "A salt is is when the H⁺  ion in an acid is replaced with a cation (e.g. a metal)" 

Part 2: You would use the silver nitrate test for halide ions. You add dilute nitri...

There are two themes in this answer. The first being the hydrogen bonding potential of HF and the second being the difference in size of the of the halide ions. Fluorine is one of three elements that can ...

The two main assumptions that are made about ideal gases are: firstly, that the volume of the gas particles themselves is negligible or zero. So, the entire volume of the container is available. Secondly ...

This is because H2S04 is a diprotic acid. If we look at how the acid dissiociates, we can see that:

H₂SO₄----------> 2H⁺+SO₄^2-

Since...
