There are basic rules in writing formulas of compounds. These are:Recommended Adam Was Not the First Human, for the Bible Tells Us So Write first the symbol of the positive ion followed by the symbol of the negative ion or radical. A radical or polyatomic ion is a group of atoms that ...
This is known as a word equation. By writing the symbols and formulae of the various substances in place of their names, we can convert this word equation into a chemical equation. Now, we know that the symbol of zinc is \(\text {Zn}\) ...
both increasing temperature and with increasing concentration of reagent, and that the reverse is also true. No valid assumptions can be made, however, if the temperature and concentration move in compensating directions. The rating some attack or absorption (symbol - ?) should not be assu...
