What is the number of electron number of manganese? What is the number of the outermost electrons in manganese?
2 Electronics.
I don't understand. Yeah. Hi.
What's the difference between heating, concentrating, cooling and evaporating in chemistry Looks like it's for KNO3 and NACL?
When you concentrate, the temperature is very high, the solubility of the substance is high, when the concentration reaches a certain concentration (usually when there is a layer of crystal film), you only need to cool down, the temperature is low, solubility becomes small, naturally there will be crystals...
