What is heterogeneous mixtures often separated by?
chemical compounds can be separated into their component elements by physical means like sifting or filtering
What injury results when two bones that comes together to form that joint become separated?
Where two bones come together or "join" is called a "joint".
Which two families of elements often combine to form ''salts''?
The family that combines with metals to form salts is the halogen family. There are other nonmetals that can be mixed with metals to form salts, but halogens are the most common.
Do elements often swap neutrons and protons with other elements?
No. Though in chemical reactions one element often gives up electrons to another.
What process often begins by portion of a population become physically or geographically separated?
Speciation

Why when we mix two elements together can we often separate them easily again?
We can separate them if they have not reacted together. The elements' atoms are unchanged by simple mixing.
Explain why other elements are often mixed with metals to make alloys?
Alloys have improved features compared with single metals.
What 2 elements did storytellers of he middle ages often blend together?
Christianity and Celtic myths.
Ask us of the following is the idea that the different peoples who have come to the US have mixed together to create a new culture?
Yes, the idea that different peoples who have come to the US have mixed together to create a new culture is often described as the "melting pot" concept. This concept suggests that diverse cultural backgrounds have blended to form a shared, distinct American identity that incorporates elements from various traditions.
Is alloy considered an element in the periodic table element?
No, an alloy is a mixture of two or metallic elements. The metals are not bonded together as a compound, they are just mixed together evenly. Alloys often have physical properties that make them more useful than metallic elements by themselves. Brass is an alloy, for example, composed of the metallic elements copper and zinc. Bronze is a mixture of copper and tin. Different proportions of the constituent metals can mean different properties, which can be changed according to how it will be used.
What are chemicals often mixed in?
Chemicals are often mixed in test tubes
Why when you mix 2 elements together you can often separate them again quite easily?
Mixtures can be separated easily, liquids by distillation, gases can be made into a liquid , and then heated gently to tap the gases off ( also called distillation) solids are a little more difficult and depend on the mixture.Compounds are much harder to separate because they are chemically bonded together.They can be separated by electrolysis but this takes a large amount of energy.
What injury results when two bones that comes together to form that joint become separated?
Where two bones come together or "join" is called a "joint".
What is in alloy?
An Alloy is two metals mixed together.it is the combination of one or more elements, usually metals. the mixture of elements in an alloy gives it new properties that are different from the properties of the individual element. it often eliminates disadvantages of the pure metal .
