What does a balanced equation show-? A balanced equation shows how many moles of each reactant is needed to form a certain number of moles of product. a balance equation must show a subscript change from elements. A balanced chemical equation has the same number of atoms of each element on both sides. The mass of the reactants is equal to the mass of products.

- Answer 1 To balance an equation means that there are the same number of each element on each side. The reason a subscript cannot change is that it represents the amount of an … element within a certain compound in relation to any other elements.If that ratio changes, it is no longer the same compound.Changing a subscript changes a formula so that it no longer stands for the correct substance. Answer 2 The point of balancing an equation is to find the ratios in which chemicals will react or be produced. By changing the equation, you change the reaction.Therefore you are not trying to balance the same reaction. Answer 3 A balanced chemical equation is the standard way of writing equations for chemical reactants because it follows the LAW OF CONSERVATION OF MASS. subscript in the formula can not be changed when balancing an equation because changing a subscript would make the formula describe a different compound, or rather more likely a non-existent compound.

Chemical equation (September 2011). 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.

What Are Coefficients in Chemistry? The need for balanced chemical equations is dictated by the law of conservation of mass. The law states that the quantity of each element involved in a chemical reaction does not change. For example, this is an unbalanced equation: N 2 + O 2 —> NO.

- In a balanced equation, when the masses of the elements on the products side of the reaction are added up, they equal the sum of the masses of the reactants. This shows that m … ass is never gained or lost.5 people found this useful.he law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.

Reaction Equations A chemical reaction equation gives the reactants and products, and a balanced chemical reaction equation shows the mole relationships of reactants and products. Often, the amount of energy involved in the reaction is given. Dealing with the quantitative aspect of chemical reactions is called reaction stoichiometry.nergy is the driving force of all changes, both physical and chemical reactions. Energy is always involved in these reactions. If a system is more stable by losing some energy, a reaction takes place, releasing energy. Such a reaction is said to be exothermic.

Balanced Chemical Equation: Definition & Examples As a result, the chemical equation that shows the chemical reaction needs to be balanced. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.he equation is not balanced because in the reactants side, there are 2 nitrogen (N) atoms and 2 hydrogen (H) atoms. In the products side, there are 1 nitrogen (N) atoms and 3 hydrogen (H) atoms. The number of the atoms is not balanced on both sides.

Forces: Balanced and Unbalanced The reason you may not notice the forces is because they are balanced. This means that the forces are equal in size and opposite in direction. The pull downward is the same magnitude as the push upward, but in the opposite direction, so they essentially cancel each other out.

Accounting equation Accounting equation plays a significant role as the foundation of the double entry bookkeeping system. This accounting system ensures that a company’s accounts are always balanced and that all financial transactions are documented in detail. The primary aim of the double entry system is to keep track of debits and credits, and ensure that the sum of these always matches up to the company assets, a calculation carried out by the accounting equation.

Balanced Chemical Equation: Definition & Examples In the products side, there are 1 nitrogen (N) atoms and 3 hydrogen (H) atoms. The number of the atoms is not balanced on both sides. To balance the chemical equation above, we need to make use of coefficients. A coefficient is a number that we place in front of a chemical formula. In the chemical equation, to make the number of nitrogen (N) atoms equal on both sides, first, we place a coefficient of 2 in front of NH3. Once we do that, the number of nitrogen (N) atoms on both sides is balanced.

Accounting Equation (Explanation) Balance Sheet and Income Statement. The balance sheet is also known as the statement of financial position and it reflects the accounting equation. The balance sheet reports a company's assets, liabilities, and owner's (or stockholders') equity at a specific point in time.Like the accounting equation, it shows that a company's total amount of assets equals the total amount of liabilities plus owner's (or stockholders') equity.The income statement is the financial statement that reports a company's revenues and expenses and the resulting net income.he accounting equation for a corporation is: Assets are a company's resources—things the company owns. Examples of assets include cash, accounts receivable, inventory, prepaid insurance, investments, land, buildings, equipment, and goodwill.

What balanced equation represents nuclear fusion? Just as in a balanced chemical equation, in a balanced nuclear equation, the sums of the superscripts and the sums of the subscripts must be equal on each side of the equation. Now that we know what these symbols represent, let's see how they can be applied to a nuclear fusion. Notice how, on each side of the equation, the superscripts add up to 4 and the subscripts add up to 2. In each case, the two reactant nuclei give a product that has more mass than either of them. These are examples of nuclear fusion.

What is a balanced chemical equation . why should chemical equations be balanced? Chemical equations must be balanced -- they must have the same number of atoms of each element on both sides of the equation. As a result, the mass of the reactants must be equal to the mass of the products of the reaction.

- one reactant a is chosen and the balanced chemical equation is used to determine the amount of the other reactant b necessary to react with a if the amount of b actually present exceeds the amount required then b is in excess and a is the limiting reagent in a reaction is the first to be completely used up and prevents any further reaction from occurring in this reaction reactant b is  because there is still some left over a in the products therefore a was in excess when b was all used up
