What is true about elements and compounds elements contain two or more compounds conpounds contain two or more elements compounds contain atoms elements do not elements contain atom compounds do not

Taking into account the concepts presented in chemistry with respect to elements and compounds, it is possible to affirm that the compounds are formed by two or more elements.

Explanation:

Two or more chemical elements have the ability to bind -by forming bonds- to obtain a compound. This occurs randomly in nature.

The bonds between the elements that form a compound must be stable enough to ensure the stability of the molecule. A chemical compound can only be separated into the elements that form it by chemical processes.

The bonds types that form compounds can be:

It is necessary to mention that chemical elements are called atoms, and the bonds between them are molecules. The physical and chemical properties of a compound will be different from the properties of the elements that form it.

b is the answer and if you need further with anything message me

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
