A chemical equation must be balanced to satisfy the law of what?
A balanced chemical reaction obeys the law of conservation of mass, because the same number of atoms of each element must appear on both sides of the equation for the reaction, and in any actual reaction, the same exact atoms will be found on both sides of the equation.
When is a chemical equation considered balanced?
The reason why Chemical equations are balanced is because each side of the equation must have the same amount of atoms, it is impossible to, for example, have this side with 3 O and that side with 4 O. How to check: Here's a really good and famous example(Guranteed your cehmistry teacher will mention this some day!): CaO + H2O = Ca(OH)2 Is it balanced? There's one Ca(Calcium) on one side, same with the other side. (Balanced!) There's 2 Oxygen on one side, same with the other.(OH)2 Means two Oxygen, two Hydrogen.(Balanced!) There's 2 Hydrogen on both sides as well(H2). So the whole thing's balanced! If it's not balanced, you can't change the numbers, you have to change the number in front. e.g. in the chemical equation of photosynthesis, there's a 6H2O. That means that there is 12 hydrogen and 6 Oxygen, change that "6" at the front to balance stuff. If there's no number at the front, that's the same as "1".
Why does a chemical equation have to be balanced?
Balancing Chemical Equations is absolutely essential if you want to determine quantities of reactants or products. An unbalanced chemical equation gives only the identify of the beginning reactants and the final products using the appropriate formulas as well as the conditions of temperature, physical state, and pressure conditions under which the reaction is to operate under. However an unbalanced equation can say nothing about the quantities involved until the equation has been balanced. A balanced equation assures that the conservation law of matter is obeyed. The total mass of reactants must equal the total mass of products. A balanced equation tells you the proportional quantities of each substance involved.
Why cant an unbalanced chemical equation fully describe a reaction?
An unbalanced chemical equation does not accurately reflect the ratio of reactants and products in a chemical reaction, which can affect the stoichiometry of the reaction. Balancing the equation is necessary to ensure that the law of conservation of mass is obeyed and to correctly represent the chemical species involved in the reaction.
What is balancing a chemical equation so that the same number of atoms of each element is found in both the reactants and the products is an example of what?
Balancing a chemical equation is an example of the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged. Balancing ensures that the total number of each type of atom is the same on both sides of the equation.
What law is used to describe a balanced equation?
The law of conservation of mass is used to describe a balanced chemical equation, which states that matter cannot be created or destroyed in a chemical reaction.
What information are conveyed by a balanced chemical reaction why is it necessary to balanced a chemical equation?
A balanced chemical equation conveys the correct molar ratios of reactants and products in a reaction. Balancing a chemical equation upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed.
What law is shown by a balanced equation?
The law of conservation of mass is shown by a balanced chemical equation, which states that matter cannot be created or destroyed in a chemical reaction. This means that the number of atoms of each element must be the same on both sides of the equation.
What chemical equations violates the law of conservation of energy?
Any chemical equations violates the law of conservation of energy.
What law of chemical change is obeyed when a chemical equation is balanced and explain?
The law of conservation of mass is obeyed when a chemical equation is balanced. This law states that the total mass of the reactants must equal the total mass of the products in a chemical reaction. Balancing an equation ensures that the number of atoms of each element is the same on both sides of the equation, thus conserving mass.
Which is a balanced chemical equation according to the law of conservation of mass?
A balanced chemical equation is one in which the number of atoms of each element is the same on both the reactant and product sides. This follows the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged. For example, the equation 2H2 + O2 -> 2H2O is balanced because there are 2 hydrogen atoms and 2 oxygen atoms on both sides of the equation.
A chemical equation must be balanced to satisfy the law of what?
A balanced chemical reaction obeys the law of conservation of mass, because the same number of atoms of each element must appear on both sides of the equation for the reaction, and in any actual reaction, the same exact atoms will be found on both sides of the equation.
Why does the law of conservation of mass dictate the chemical equation be balanced?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. Therefore, in a balanced chemical equation, the number of atoms of each element must be the same on both sides to ensure that mass is conserved. If the equation is unbalanced, it would imply that mass is not conserved, which goes against this fundamental law of chemistry.
How is the law of conversion of mass shown by a balanced chemical equation?
The law of conservation of mass is shown by a balanced chemical equation because the total mass of the reactants must equal the total mass of the products. This is achieved by ensuring that the number of atoms of each element is the same on both sides of the equation. Therefore, mass is conserved in a chemical reaction.
. How is the law of conservation of mass shown by a balanced chemical equation?
In stoichiometry, the equation is balanced by using molar ratios. Because each item on either side of the equation has a specific molar mass, it can be demonstrated that all mass is conserved through the chemical reaction.
On what basis is a chemical equation balanced?
A chemical equation is balanced by ensuring that the number of atoms of each element is the same on both sides of the equation. This is done by adjusting the coefficients in front of the reactants and products to achieve this balance while following the law of conservation of mass.
What is a balanced chemical equation why should the chemical equation be balanced?
A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example: 2H20 --> 2H2 + O2 This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction). Technically the equation wouldn't work in real life if it weren't correctly balanced.
