What is a Chemical Equation?

Chemistry is a subject of various reactions taking place and these reactions are represented using the chemical equations. The chemical equation balancer plays a huge contribution in chemical reactions as it is the standard way of representing a chemical reaction.

In a chemical equation the reactants and products involved in a chemical reaction are represented symbolically. The reactants or the reacting substances are represented on the left hand side of the equation while the products or resultant entities are presented on the equation's right hand side.

Both the reacting and producing substances are separated in the equation by an arrow. However, the direction of the arrow represents whether the reaction is reversible or irreversible. 

Law of Conservation and Balanced Chemical Equation

In chemical equations the equilibrium or balance on both hand sides is an imperative factor. A chemical equation must be balanced accurately in order to maintain an equilibrium among reactants and products. Moreover, the law of conservation of mass, which states that mass can neither be created nor destroyed during a chemical reaction, must need to be fulfilled.

In other words, the foundation for a balanced chemical equation is the law of conservation of mass. And when implementing this law, the number of each element or compounds, atoms and molecules in the equation should be kept equal on both hands. 

Thus a balanced chemical equation should maintain an equilibrium among atoms and molecules of reactants and products. The number of atoms in a chemical equation is represented by the subscripts before the element’s symbol. While the number of molecules involved in the reactions are represented by the coefficient written just after the chemical formula.

However, when writing chemical reactions in equation form you have to balance them by your own as they don’t come already balanced. So before using any equation in your required chemical reaction first balance it accordingly ten deal with it.

The law of conservation of mass which governs the equation balancing is that we must present as many atoms and molecules with the products as much we have with the reactants. Thus the total mass of the products must be equal to the total mass of the reactants. Balancing

What is Half life

The half-life is the phenomenon that is a part of physics, chemistry as well as the biological field. As the name implies the half-life is something related to the half-life or half existence of matter or substance.

However, we would define it as the time required by the half of a reactant or chemical substance to be consumed from the initial quantity. This means the half-life of any substance is the time taken by it to be converted into half quantity from the preliminary quantity.

The thing to be considered here is that the half-life of any substance has nothing to do with its physical quantity. That means there should be no change in the mass of the substance, however, the 50 percent decay of the substance's atom will occur. Online half life calculator with steps define half-life process very clearly and calculate the half-life accurately.

For instance, if a radioactive substance has a half-life of 70 years that means after 70 years half of its atoms would undergo chemical decay with no change in mass. The half-life of any element could be as much as billions of years to as minimum as a few seconds. However, it is expressed in seconds and denoted by the expression t1/2.

This significant property of matter decaying is highly implemented in nuclear physics, to calculate the timing required to undergo radioactive decay by unstable atoms and for how long the stable atoms could survive.

As mentioned above, in order to calculate the half-life of any substance the expression t1/2 expression is used but along with this expression following aspects must need to be known as well:

Rate constant which is expressed as “k”

Order of the reaction

Initial concentration which is expressed as [Ao]
