Explain why when you mix two elements together, you can often separate them quite easily via physical means, yet when two elements are chemically combined in a compound, they are usually difficult to separate. (2)
Added by Gina P.
Step 1
When two elements are mixed together, they are typically held together by physical forces such as intermolecular forces (like van der Waals forces or hydrogen bonding) or mechanical forces (like mixing). These forces are generally weaker than chemical bonds. Show more…

1. Why do you think some elements naturally occur as single atoms whereas others are always present in the form of diatomic molecules? 2. The properties of a compound are usually different than the properties of the elements it contains. (true or false) 3. A mixture is a combination of substances that involves the breaking and formation of chemical bonds among those substances. (true or false) 4.In a mixture, the substances retain their original chemical compositions and identities. (true or false) 5.In a mixture the substances involved can usually be separated by a simple physical process. (true or false) 6. The elements in any given compound can be separated by a simple physical process. (true or false)

In what main way is separating the components of a mixture different from separating the components of a compound?
Both mixtures and compounds are made of two or more different substances mixed together. So which of the following is an accurate statement about the difference between the two? a- generally speaking compounds are easier to separate than mixtures b- compounds are mixed physically but not chemically c- a mixture is two or more substances mixed physically but not chemically d- mixtures are pure substances while compounds are not
