Yeah, so compound just separate by chemical means. It's always been like that and that's the way that it will no doubt stay

What substance only contains more then one type of atom chemically joined together?
alkali
What does it mean when something is a pure substance?
A pure substance is an element or a compound. In the case of an element, it is composed of all the same kind of atoms. In the case of a compound, the atoms of the elements are chemically bonded in definite proportions, meaning that all samples of the same compound are chemically the samel.
What does the addition or subtraction of heat have to do with whether or not a substance is a solid liquid gas or plasma?
When heat is added or subtracted, it chemically changes the substance into a different type of matter.
What type of mixture can only be separated by evaporation?
homogeneous and heterogeneous mixtures are separated by evaporation
What type of materials can be separated by a physical process?
Heterogeneous mixtures are separated by physical means.
What substance only contains more then one type of atom chemically joined together?
alkali
What type of matter cannot be physically or chemically separated?
A compound.
What is a substance that is not a compound called?
A substance can be a mixture or solution, rather than a compound. These do not require that the separate substances combine chemically. An element is a substance that has only one type of atom.
A pure substance is matter that has a fixed what?
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.

What type of substance can be separated by filtration?
Suspension (solid particles) in a liquid can be separated by filtration.
What type of solids that can not be separated?
Chemically or physically. Chemically, elements can not be broken down. Chemically, a mixture of solids can be seperated in most cases through solubility, precipitation, and by using chemicals.
Is banana an element or compound or mixture?
An element is a stand alone type of particle that is not bonded with any other element. A compound is a group of elements chemically bonded together like water being H2O and can only be separated by chemical means. A mixture is a group of compounds mixed together but they are not chemically bound to each other and can be separated by non-chemical means. The banana is made up of many compounds but is itself not a compound as those compounds are not bonded together chemically and can be mechanically separated. This makes the banana a mixture.
What does the addition or subtraction of heat have to do with whether or not a substance is a solid liquid gas or plasma?
When heat is added or subtracted, it chemically changes the substance into a different type of matter.
What are substances that can not be broken down into simpler stuff by any chemical means?
The simplest substance that you can obtain by ordinary means is an element.An element is a substance than cannot be separated or broken down into simpler substances by chemical means.
Is white sugar a mixture or a substance?
Table sugar is a pure substance. It is made up of one type of molecule that cannot be separated into two or more components. Mixtures can be separated. For example, a mixture of water and sand can be separated into two components. Other examples of pure substances are diamonds, and table salt.
What substance is a substance in which there is only one type of particle?
a pure substance
