What cannot be separated into its individual elements by physical means?
Various chemical compounds eg Hydrogen Peroxide.
What did Alfred Wegender mean by ''continental drift''?
He means that all of the continents were once connected, but plates shifted and they were seperated.
A solution can be distinguished from a compound by its?
A solution has many distinguishing features when compared to its compound. The components of a solution can be separated by physical means, but this cannot be done.
Standards of measurement are chosen because they... a. are reproducible in another laboratory. b. cannot be destroyed by any common physical or chemical means. c.are easily changed.?
A
A pure substance that cannot be broken down into other substances by chemical means?
A substance that can not be decomposed into simpler substance by a chemical or physical means is a chemical element.
Why water is regarded as a compound although it can be separated into hydrogen and oxygen by passing an electric current?
The property of copounds is that they can be seperated only by hemical means and not by physical means. Water is a compound since it cannot be seperated by physical means. Seperation into hydrogen and oxygen is a chemical mean.
Can Mixtures be seperated?
Mixtures can be separated by physical means.
Can gold be seperated into simpler substances only by chemical means?
It cannot be separated at all. It is an element.
Can a compound be seperated into its consistent elements by physical methods?
Yes it can. Water, table salt, and sugar are all examples of compounds and can all be decomposed into simpler substances through physical means.^^ I believed that water and table salt would be a mixture, mixtures are the non-chemical means not compounds, with compounds there is a chemical change.
Is sugar dissolved in water a compound or element?
It is a solution, which is a mixture of two or more substances which, when dissolved, cannot be seperated by mechanical means.
Which thing is not homogeneous?
a homogeneous is a thing that cannot be seperated
A sample that cannot be separated into two or more substances by physical means is what?
A sample that cannot be separated into two or more substances by physical means is a compound. A compound is made up of 2 or more elements which cannot be broken down by physical means.
Can a compound be separated by a physical means?
no, it can not be separated by a physical process.
What are some properties of mixture?
Made of elements compounds, or both No change in oringinal properties of components Seperated by physical means Formed using any ratio of components
What are some properties of a mixture?
Made of elements compounds, or both No change in oringinal properties of components Seperated by physical means Formed using any ratio of components
A substance can be seperated into simpler parts through differences in physical properties?
Mixture
Two or more elements that chemically bonds can be separated by what process?
It can be seperated by physical process
