What does it mean when a chemical equation is balanced?

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.

How do you know if a chemical equation is balanced?

If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.

Why is it important that a chemical equation be balance?

A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.

What happens if a chemical equation is not balanced?

Chemical reactions must be balanced, or in other words, must have the same number of various atoms in the products as in the reactants. If a chemical reaction is not balanced, no information about the relationship between products and reactants can be derived.

What are two reasons for balancing chemical equations?

Chemical equations are balanced in order to: 1) satisfy the Law of Conservation of Mass, and 2) establish the mole relationships needed for stoichiometric calculations. The Law of Conservation of Mass: The Law of Conservation of Mass states that mass cannot be created or destroyed.

What are the 5 types of chemical reaction?

Classify chemical reactions as synthesis (combination), decomposition, single displacement (replacement), double displacement, and combustion.

How do you balance an equation algebraically?

The strategy for balancing chemical equations algebraically is as follows:Write a different letter coefficient in front of each compound in the equation.Write algebraic expressions or rules for each element that equate its atoms on the LHS and RHS.

What defines a chemical reaction?

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

What are the types of chemical reactions?

Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.

The supply function is the mathematical expression of the relationship between supply and those factors that affect the willingness and ability of a supplier to offer goods for sale. An example would be the curve implied by where is the price of the good and is the price of a […]

Law.Of conservation of momentum equation

What is the formula for the law of conservation of momentum? It’s hard to imagine how momentum could still be conserved, but it is. The equation for conservation of momentum looks like this: total momentum before = total momentum after. pbefore = pafter. (m1v1 + m2v2)before = (m1v1 + m2v2)after. What is law of conservation […]
