There are some basic rules to follow to decide when to use a capital letter and when to leave the first letter lowercase. Actually, maybe I should state that many rules in English capitalization, do not apply in Spanish. In Spanish you do not capitalize the names of the days of the week, or the months of the year.
Equations and Expressions are closely related. The primary difference between the two is an equals sign. An equation has a left side, a right side and an equals sign separating the sides. An expression, by contrast, doesn't have any sides and is simply what the name suggests: An algebraic expression.. Though sometimes it is possible to combine like terms, we are generally not expected to do or solve anything regarding expressions.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.herefore, the same charge must be present on both sides of the balanced equation. One balances a chemical equation by changing the scalar number for each chemical formula. Simple chemical equations can be balanced by inspection, that is, by trial and error.
