There are 3 basic parts to a chemical equation: reactants, products, and the “yields” arrow. Reactants are compounds or elements that are needed in the reaction and that undergo chemical change during the reaction. In reactions, “yield” means to “produce” or “form” and is usually represented by an arrow.

What must a chemical equation contain?
A chemical equation consists of the chemical formulas of the reactants (on the left) and the products (on the right). The two are separated by an arrow symbol (“→” usually read aloud as “yields”). Each individual substance's chemical formula is separated from others by a plus sign.
What are the 4 types of chemical equation?
The main four types of reactions are direct combination, analysis reaction, single displacement, and double displacement.
What are the parts of chemical reaction define each?
The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
What are the products in the equation?
The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products.

What is the left part of a chemical equation called?
reactantsThe substances that "go in" to a chemical reaction are called the reactants (by convention these are usually listed on the left side of a chemical equation), and the substances found that "come out" of the reaction are known as the products (by convention these are usually found on the right side of a chemical equation ...
What are the atoms in a chemical equation?
In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products. If we count the number of hydrogen atoms in the reactants and products, we find two hydrogen atoms.
Which of the following features is involved in a properly written chemical equation?
i) temperature required. ii) should be balanced. iii) should have information regarding physical states.
What is a Chemical Equation?
Chemical reactions occur constantly. The digestion of food is a chemical reaction. A plant's photosynthesis is a chemical reaction. Even breathing air is a chemical reaction. A chemical reaction can be expressed through a chemical equation. But what is a chemical equation?
Chemical Equation Components
Reactants are one of the most important chemical equation components. They are always written in the left-hand side of the equation as symbols. These symbols can represent individual atoms, elements, or even compounds. The symbols used are not random; they come from the periodic table.
Chemical Equations
Chemical equations tell us the elements and/or compounds that are reacting and what the product (s) of the reaction. The coefficients on the substances in the reaction tell us the mole ratio or molecular ratio of the elements/compounds in the reaction.
What is chemical equation?
What is a Chemical Equation? Chemical equations are symbolic representations of chemical reactions in which the reactants and the products are expressed in terms of their respective chemical formulae. They also make use of symbols to represent factors such as the direction of the reaction and the physical states of the reacting entities.
What does the left side of a chemical equation represent?
The left-hand side of a chemical equation represents the reactants and the right-hand side represents the products. These entities are separated by a symbol that describes the direction of the reaction. Each reacting entity is also assigned its corresponding stoichiometric coefficient.
What are electrolytes represented in?
The chemical equations in which electrolytes are represented in the form of dissociated ions are commonly referred to as ionic equations. They are often used to represent the displacement reactions that take place in aqueous mediums. In these reactions, some ions participate in the reaction and some do not.
What are the spectator ions in the ionic equation?
Comparing the reactants and the products of the ionic equation and the chemical equation, it can be observed that the Ca 2+ ( calcium ion) and the NO 3– (nitrate) ions are present on both sides of the ionic equation. These ions are referred to as spectator ions because they do not participate in the chemical reaction.
What is the purpose of ionic equations?
In ionic chemical equations, the electrolytes (substances that dissociates into ions when dissolved in polar solvents) are split up and written as separate ions. These equations are very useful in describing single displacement reactions and salt metathesis reactions (generally referred to as double displacement reactions).
What symbol is used to describe a net forward reaction?
The reactants and the products (for which the chemical formulae are written in chemical equations) can be separated by one of the following four symbols. In order to describe a net forward reaction, the symbol ‘→’ is used. In order to describe a state of chemical equilibrium, the symbol ‘⇌’ is used. To denote stoichiometric relationships, the ‘=’ ...
What are coefficients in chemical equations?
These coefficients of entities in a chemical equation are the exact value of the stoichiometric number for that entity.
What are the main parts of a chemical equation?
Atoms & Molecules in an Equation. As you've learned, the main parts of a chemical equation are the reactants and the products. Besides these, however, there are other pieces of information represented in a chemical reaction.
What is chemical equation?
What's a Chemical Equation? A chemical equation is a short-hand way to represent the components of a chemical reaction. There are several pieces of information provided in a chemical equation for those working with the chemical equation or corresponding chemical reaction.
How are chemical equations different from mathematical equations?
Chemical equations are different from mathematical equations because the two parts of a chemical reaction represent the 'before' and 'after' of a chemical reaction. In mathematical equations, an equals sign separates the two parts of the equation. In chemical equations, equal signs are not used. Instead, an arrow is used to separate ...
What is the subscripted number of a chemical species?
A subscripted number is the number of atoms in a particular chemical species.
How many atoms are in a reaction 3?
Reaction 3. There are 6 atoms of sodium in this reaction. The sodium atoms as products are the same as the sodium atoms as reactants. The aluminum atoms in a chemical bond as reactants separate from the other atoms to be isolated as a product.
Why is it important to understand chemical reactions?
Because a chemical equation represents a chemical reaction, it's important to understand what a chemical reaction is. You observe chemical reactions taking place every day. A chemical reaction occurs when matter is rearranged to form a different or new substance.
What is the coefficient in front of reactants?
It is the coefficient placed in front of the reactants and products that balance the chemical components of an equation, and you will learn how to balance chemical equations using coefficients in another lesson. In the following equation, note that there is a 3 in front of molecular hydrogen and a 2 in front of ammonia.

- Chemical equations make use of symbols to represent factors such as the direction of the reaction and the physical states of the reacting entities. Chemical equations were first formulated by the French chemist Jean Beguin in the year 1615. Chemical reactions can be represented on paper with the help of chemical equations, an example for which is represented below (for the re…
