It can be either they can have a negative or positive charge more specifically negatively charged molecule would called an anion and a positive one would be cation.
First its ... higher energy of reactants , higher energy of products & you do the same with the lower ones than you do transition state
Water is made of only one molecule which can be chemically separated into hydrogen and oxygen. The answer is D.
Fluorite is harder than gypsum but softer than apatite. Thus, the correct option is B.
<h3>What is the hardness of any element?</h3>
The hardness of any element may be defined as the capability of a material to oppose the process of deformation and remains in actual shape precisely.
According to the table of hardness scales by Mohs, the increasing order of given hardness of given elements is as follows:
Gypsum < Fluorite < Apatite.
Therefore, Fluorite is harder than gypsum but softer than apatite. Thus, the correct option is B.
