Input: reactants --> [ They react ] --> Output: products = what you get out of it
The same elements and the same quantity of those elements.
The reactants and products of a chemical change have nothing in common - hence the name "chemical change".
acid
Almost any chemical element or compound can participate in some type of chemical reaction and thereby be a reactant. One of the more common reactants is oxygen. It may be that only helium can never be a reactant.
Carbon dioxide is the most common respiration product
This question depends on your definition of acids and bases. Assuming we are talking about simple neutralization of acids and bases in water as a solvent, then the reactants are hydrogen and hydroxide ions and the product is water.H+(aq) + OH-(aq) --> H2O(l)At an even simpler level we can say acid + base --> salt + water.
Combustion involves many different reactants and produces many different products. There are endless numbers of things that can burn, and endless types of chemicals released when these things burn. Added: Generally, and what you will see in an academic setting, this; A hydrocarbon, or a carbohydrate with oxygen gas as the reactants. The products are always carbon dioxide and water. CH4 + 2O2 --> CO2 + 2H2O An example of a common combustion reaction.
A simple definition of a chemical reaction is a reaction in which chemical bonds are broken and/or formed. Under the right conditions (temperature, pressure and catalyst) the following reaction may run: 2CH4 -> C2H6 + H2 Although in this case two molecules of the same reactant was needed, only one reactant was needed. So, the direct answer to your question is no.

In an equation the reactants are the on the left of the arrow, and the products are on the right. For example if you had the following equation: 2H2 + O2 => 2H2O 2H and O will be the reactants and H2O is the product.
The products of a chemical reaction have different properties than the reactant because they underwent a chemical change by definition of a chemical reaction. The products are new combinations atoms forming different molecules.

Carbon dioxide is the most common respiration product
These are common products of combustion reactions.
Balanced and unbalanced chemical equations have the same elements on both sides, they have just been recombinded to form new products from the reactants.

There are many products that we use every day that are developed with a chemical reaction. Some examples of daily chemical reactions are; medication, the use of a propane grill and breathing.
There are several ways that the rate of reaction may be increased. Some of the more common ways areincrease temperatureincrease surface area (grind or powder the reactants)use a catalystagitate/stir the reaction mixture
