and pentagons. chemists have to write chemical equations all the time and it would take too long to write and read if they had to spell everything out. so chemists use symbols just like it’s done in maths. each element has a symbol. there’s a particular way of writing what’s in...
Notations for Chemical Equations A chemical equation is composed of chemical formulas. It has reactants on the left and products on the right side of an arrow symbol (→). The arrow is usually read out as ‘yields’. In an equation, all chemical formulae on one side are separated by a...
