Which of the following correctly describes a compound? the atoms are bonded together, and the compound has different physical and chemical properties than the individual elements. the atoms have no set ratio for how the atoms can combine, and they are not chemically bonded together. the atoms can only combine in fixed ratios, and they retain their individual chemical and physical properties. the atoms retain their individual chemical properties, and they can only be separated from each other by a chemical change.

A chemical compound can be described as substance composed of atoms from more than one element held together by chemical bonds in a fixed stoichiometric proportion. A compound has different physical and chemical properties from its constituent elements.

For example : compound water is made up of H and O bonded together and it has different properties from O and H.

Thus, among the given options, the one coreectly describing a compound is

a) The atoms are bonded together, and the compound has different physical and chemical properties than the individual elements.

Answer;

The atoms are bonded together, and the compound has different physical and chemical properties than the individual elements.

Explanation;

-A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.

-A chemical formula is used a quick way to show the composition of compounds. Letters, numbers, and symbols are used to represent elements and the number of elements in each compound.

yes it is balanced

the temperature of the gas, in k, not celsius.
