The three main parts of a chemical equation are the reactants, the arrow representing the reaction, and the products. Reactants are the substances that participate in the reaction, while products are the substances formed as a result of the reaction. The arrow indicates the direction of the reaction from reactants to products.
Formation of a precipitate or gas: A visible solid (precipitate) forming when two solutions are mixed or the evolution of a gas (bubbles) indicates a chemical reaction. Color change: A change in color during a reaction suggests that new substances with different properties have formed. Temperature change: Exothermic reactions release heat, leading to a temperature increase, while endothermic reactions absorb heat, causing a temperature decrease.
Gunpowder is made up of three main components: potassium nitrate (also known as saltpeter), charcoal, and sulfur. These ingredients undergo a chemical reaction when ignited, producing the explosive combustion that propels a bullet out of a gun.
For a chemical reaction to occur, typically three things need to happen: reactant molecules must collide with enough energy to overcome activation energy, proper orientation of colliding molecules must occur, and the reaction must proceed in a way that forms new chemical bonds and products.
The chemical reaction between ammonia (NH3) and hydrogen (H2) is as follows: 3H2 + N2 --> 2NH3 This reaction results in the formation of ammonia (NH3) by combining three molecules of hydrogen gas (H2) with one molecule of nitrogen gas (N2).
Yes because it has two out of three things which are heat and two things that make a gas which is also called a chemical reaction
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
The type of chemical reaction that takes place through the formation of the rubber is called the mechano-chemical reaction. Through this, it gives the end product a three dimensional structure.

The arrow indicates the direction of the reaction from reactants to products.
To make fire, you need three things: fuel to burn, heat to ignite the fuel, and oxygen to sustain the combustion reaction. These three components combine to create a self-sustaining chemical reaction known as fire.
Polymerisation is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
Chemical equations can tell you the identities of the reactants and products involved in a reaction, the stoichiometry of the reaction (i.e., how the reactants and products are related in terms of moles), and the amount of heat released or absorbed during the reaction.
