Scientists are working with a liquid that is made of only one type of atom. which statement correctly describes this liquid? check all that apply
1. the liquid contains only one compound
2. the liquid contains only one element
3. the liquid contains only neutral electrons
4. the liquid is a pure substance
5. the liquid can be broken down into simpler substances
6. the liquid must have equal numbers of neutrons and protons

From the given statements only statements correct are 2 and 4.

Explanation:

Substance made up of only one type of an atom is known as pure substance.

Pure substance is composed of only one type of an element.

The pure substance cannot be broken down into simpler compounds.

So, from the given statements only statements correct are 2 and 4.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

b.

the accuracy of the data.
