Which type of reaction generally takes place only between substances in aqueous?
Example: double displacement reaction.
Examples of a mixture?
Any dilute solution of a given chemical reagent is an example for a mixture in liquid phase.
What Discribe the following type of mixture and give on example one?
A mixture is when two or more different substances are mixed together but not combined chemically.granite stonedry cereal with nuts and dried marshmallow shapescereal in milkmilkgasolineetc.
What is the chemical equation of displacement reaction?
For example a single displacement reaction is:2 Na + 2 HCl = 2 NaCl + H2
How does distance differ displacement?
Distance is the total length travelled where as displacement is the length between where you started and where you are now. example.. If you travel in a circular path, around the whole circle and wind up back where you started. Your displacement will be zero but your distance travelled will be the circumference of the circle.
Which type of reaction generally takes place only between substances in aqueous?
Example: double displacement reaction.
What is the relationship between displacement and direction?
Displacement is just distance traveled and a direction. For example 40m east is a displacement distance
What consists of two or more substances that are in the same place but not chemically combined.?
A mixture
What is the major difference between distance and displacement?
Distance is how far you have traveled. For example, if you walk to school and back, you will have traveled twice the distance between the school and your home. Displacement is how far you have gone in your travels. For example, if you walk to school and back, your displacement is zero because you end up where you started.
What consists of two or more substances not chemically combined?
mixture [mec3usa] Hydrated calcium sulphate is one example. The water in the substance is not chemically combined with the salt (CaSO4).
In what two ways can elements occur nature?
They can occur as either pure substances, for example native gold and sulphur, or combined with other substances in the form of compounds, such as ores.
A substance formed when two or more other substances are combined and a chemical change takes place?
A compound is formed when two or more other substances are combined and a chemical change takes place. Pure water would be an example of a compound.
Can a combined substance be separated physically?
A substance that is chemically combined cannot be separated physically.In some situations, you can and can't separate combined substances physically. For example, you can separate sand from rocks physically, but you cannot separate water and ice cream, even though the substances did not undergo a chemical change, because the water soaked into the ice cream.
When two pure substances are combined so that each of the pure substances retains its own properties the result is a?
When two or more substances are combined so each substance can be separated by physical means the result is a mixture. An example is dissolving salt in water. By boiling off all the water, the salt will remain.
What does mixturing mean?
A mixture is a group of substances that are not chemicaly joined together. So can be easly seperated. for example if you mixed together a packed of smarties and M$N'S it you are not creating a new chocolate just mixing M$N'S with smarties. A mixture is composed of two or more substances that are not chemically combined.
Examples of a mixture?
Any dilute solution of a given chemical reagent is an example for a mixture in liquid phase.
What is a characteristic of a vector?
It has only magnitude and no direction. It depends on magnitude of two vectors which are multiplying and cosine of angle between them. A . B = AB (cosine of angle between them). Best example is 'work done by a force' = force . displacement = Fd(cosine of angle between force and displacement)
