Is mixing chemicals ALWAYS safe?
Mixing chemicals can be safe if you know what will happen or what to do. However, you should never mix random chemicals together.
What happens when atoms of different elements form compounds?
The valence electrons are shared or transferred to achieve a stable electron figuration.
What’s the difference between parallel circuits and series circuits?
