Do the chemical substances found in the atmosphere exist as a mixture?
Atmosphere composition: nitrogen, oxygen, argon; impurities are carbon dioxide, water, powders and many others depending upon region, climate, altitude.
Many elements found in nature exist as?
The chemical substances found in the atmosphere exist as gases.
Is there such thing as scientific names of substances?
Yes; today official scientific names of chemical substances are established by IUPAC (International Union of Pure and Applied Chemistry). Each country has a specific adaptation for this terminology. Also, exist numerical codes for chemical substances: CAS registry number (CAS is Chemical Abstract Service).
What caused te Earth's atmosphere to exist?
What caused the Earth's atmosphere to exist?
Is ability to react with other substances chemical or physical?
This is a chemical reaction. When substances change you can call it chemical.
How the chemical combination of substances take place?
A chemical substance is a material with a specific chemical compound. A common example of a chemical substance is pure water; it has the same properties and the same ratioof hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Some typical chemical substances are diamond, gold, salt (sodium chloride) and sugar (sucrose). Generally, chemical substances exist as a solid, liquid, or gas, and may change between these phases of matter with changes intemperature or pressure. Chemical reactions convert one chemical substance into another. Forms of energy, such as light and heat, are not considered to be matter, and thus they are not "substances" in this regard.
What is the relationship between the chemical properties of a substances and the chemical changes of a substances?
The chemical properties of an object show what a chemical change did to that substance.
The only sure evidence for a chemical reaction is?
A kind of chemical bond in the possible reaction products that did not exist in the reactants, or a kind of chemical bond in the reactants that does not exist in the possible reaction products.
This is a process in which substances change into new substances with different properties?
Chemical Change
What is a substances that undergo a chemical change?
Substances that undergo chemical change are called reactants.
What are the substances that are present before a chemical reaction starts?
The reactants exist before a reaction begins, and also the products are the result of the reaction of the reactants.
Chemical change definition?
A chemical change involves altering substances. One or more substances are changed into different and new substances in this process.
