Which of these best describes a scientific law? a rule made by a government a statement which is always true under the same conditions a rule that is sometimes broken by people under certain circumstances a statement that does not depend on observable evidence in the natural world

A statement which is always true under the same conditions

Explanation:

A scientific law is usually drawn from careful testing of a hypothesis. It is a formulation that seeks to provide a simple solution to certain observations.

Most scientific laws are always true under specific and certain conditions. Some scientific laws often comes with the idea of exceptions. Exceptions provide certain limits through which a hypothesis is still relevant. Outside of these conditions, the law might be rendered inconsistent.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
