When an Arrhenius base is
placed in H2O, the only negative ion present in the solution is OH-.
<span>Hydroxide is a diatomic anion with </span>chemical<span> formula</span>OH−. It consists of an oxygen and hydrogen atom held together by
a covalent bond, and carries a negative electric charge.
This is Avogadro's Law. Amedeo Avogadro was the first to hypothesize that this was the case.
Answer:
The symbol used to separate the product from each other or reactants from each other is 'plus' (+) .
Explanation:
In chemical equation the symbol used to separate the product from each other or reactants from each other is 'plus' (+) .
While the symbol used to separate the reactant and product from each other is '→'
For example:
Consider the following reaction.
2H₂ + O₂ → 2H₂O
Two moles of hydrogen react with one mole of oxygen to form two moles of water. The both reactant hydrogen and oxygen are separated by the + while reactant and products are separated by → .
This reaction is called an exothermic reaction.
