What is a change in which one or more substances are converted into two substances?
A decomposition reaction is a change in which one substance is broken down into two or more substances. This type of reaction is the opposite of a combination reaction, where two or more substances combine to form one product.
What is a mixture of two or more substances?
A combination of two substances that do not chemically react can be a mixture or a solution.When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.
Definition of a chemical reaction?
A combination, or synthesis, reaction, is one in which two simpler substances chemically combine to form a more complex substance. For example, the reaction between hydrogen and oxygen to form water is a combination (synthesis) reaction. 2H2 + O2 --> 2H2O
Is a process in which a substance or substances is transformed into one or more new substances?
Chemical Change
What are reactants and products?
Reactants (or 'substrates') are two or more elements/ compounds that chemically interact to form a new substance. They are the starting materials for a reaction and are always found at the left side of a chemical equations.A reactant is one of the inputs in a reaction, that get changedThe word reactant is used in chemistry. A substance that has a reaction and undergoes a change is considered reactant.
What is a chemical reaction with two or more substances combined to make a more complex compound?
synthesis
What is two or more substance only physically combined is what?
A mixture is when two or more substances are physically combined but can be separated by physical means, such as filtering or distillation. The substances in a mixture retain their individual properties and do not undergo a chemical reaction.
What a two or more substances that are combined chemically?
Two or more substances which can chemically react form new chemicals after the reaction.1. If these chemicals react they form new compounds.2. Without a chemical reaction they form a mixture.Read more: What_is_two_or_more_substance_are_combined
When two or more substances are combined will the temperature rise or fall?
Combination of two or more compounds is generally an exothermic process but endothermic processes exist.
What happens When 2 or more substances combine chemically?
When two or more substances combine chemically, they undergo a chemical reaction where their atoms rearrange to form new chemical bonds. This results in the formation of one or more new substances with different properties than the original substances.
What are two or more substances that are together but not combined?
two or more subsantes (a mixture of substances) !
Two or more substances that are not chemically combined are called what?
mixed substances
If two or more substances are combined what is always created?
When two or more substances are combined, a mixture is always created. In a mixture, the individual components retain their distinct properties and can often be separated by physical means. In some cases, if a chemical reaction occurs, new substances called products may be formed. However, the initial combination itself results in a mixture.
Mixtures?
2 or more substances physically combined, or having no chemical bond
What is 2 or more substances that are not chemicaly combined?
mixture
What is a change in which one or more substances are converted into two substances?
A decomposition reaction is a change in which one substance is broken down into two or more substances. This type of reaction is the opposite of a combination reaction, where two or more substances combine to form one product.
What is the substances you have when a chemical reaction is complete?
In a chemical reaction, two or more substances called reactants react, resulting in substances called products.
