Because you are not combinding any substances, you are just putting then in the same group.
yes, that's called colligative chemistry, like aspires to like, by symetry I suppose. If you mean a mixture, then the mixture is still not a chemical, so it has saturation points which make crystals depending on the solubility and temperature. They tend to be composed of a set of large molecues that could be construed as almost any electronic device that isn't working properly. So, symetry creates a slugish slob, so you can decompose whatever meaning you wish.
Yes, because a mixture can be separated out into its components.
In a mixture.
yes
no.
Yes
Yes.
You are describing a mixture.
no, it never does.
No, physical and chemical properties of species that we have in the beginning of a chemical reaction undergoes oxidation and reduction reaction. This gives us product species that is completely different that reactants. Rate of reaction can be calculated by kinetics.
They keep their own properties.
A MIXTURE is matter made up of two or more substances that are combined physically, but keep their individual properties.
yes, because a solution is a mixture, and mixtures keep their component's original properties because the components are not chemically combined to each other. hope this helps:)
I believe you are talking about a mixture. A mixture is a physical blend of two or more substances where each substance retains its own properties. Since they keep their properties, mixtures can be separated into their original individual substances. Example: If you had a mixture of salt and sand, you could separate them by pouring the mixture into a container of water. Salt is soluble in water and will dissolve. You can then pour the salt water through a filter, capturing the sand. Then, by evaporating the water, the salt will be left.
Some, but not all, substances do so. Such substances are known as catalysts.
Yes
Yes.

You are describing a mixture.
no, it never does.
A mechanical mixture is a mixture in which the components can be separated by mechanical means. In other words, there is no chemical bonding. The parts keep their own properties and chemical make up.
No chemical change happens when a mixture is made. So, each substance in a mixture has the same chemical makeup it had before the mixture formed.
