What are the three main parts of a chemical equation?
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.
What are 3 things that show evidence of a chemical reaction?
- change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence - formation of new compounds
What three things make up gunpowder?
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.
What 3 things need to happen in order for a chemical reaction to occur?
This isn't answerable without knowing what the chemical reaction is. Some reactions are very easy to initiate - alkali metals and halogens will react with little to no prodding. Others require intermediate reactions.
What is the chemical reaction between ammonia and hydrogen?
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).
Is vinegar and baking soda a combustion reaction?
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
What Three Things can happen when a Chemical Reaction occur?
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.
What is the chemical reaction for the formation of rubber?
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.
What are the three main parts of a chemical equation?
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.
What are the 3 requirements are needed to make fire?
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.
What is polymerisation reaction?
Polymerisation is a process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
What are three things that chemical equations can tell you about a chemical reaction?
A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
What is one of the three things needed to make a strong argument?
One of the three things needed to make a strong argument is evidence to support your claims.
What are Three things all living things need?
oxygen,water and chemical energy (food)
What are three things that are contaminated?
raw sewage, chemical pesticides and fertilizers
What are three factors of the speed at which a chemical reaction happens?
temperature presence or absence of a catalyst concentration of reactants
What are 3 things that show evidence of a chemical reaction?
- change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence - formation of new compounds
