Is it true that chemical properties of matter cannot be determined from the composition of matter alone.?
Several chemical properties can be estimated knowing the chemical composition.
What is the significance of boiling point and melting point of a substance?
Melting points and boiling points are phyical constants which means specific compounds have specific melting/boiling points. Therefore you can identify a substance if you determine the mp/bp. Also you measure the purity of a mixture using melting point tests.
How could you use the physical properties of melting and boiling point to identify a substance?
If you know the melting point and boiling point of a substance, you could look them up in a table to see what substances have those melting and boiling points. In practice, there are lots of other tests you'd probably want to do in addition, because in general there's no guarantee that an unknown substance is a single pure compound.
Match each of Earth's properties to the observation it affects?
To know what properties go with what effects the choices for both will need to e given. Not knowing what the properties or effects are will not allow someone to know the answer.
What conclusions can you draw about a planets properties just by knowing how far it is from the sun?
temperature, orbit...........................
Can knowing about chemical properties can help identify elements and compounds?
Reacts with other substances.
Is it true that chemical properties of matter cannot be determined from the composition of matter alone.?
Several chemical properties can be estimated knowing the chemical composition.
Knowing the chemical properties of a substance helps you to?
This help to use correctly this substance.
How are physical and chemical properties of matter useful?
Physical and chemical properties of matter are useful because they can help you identify that substance. For example paper burns very easily and aluminum doesn't, this is how they can be described individually.
How can knowing the physical properties of a substance be useful?
The physical properties of a pure substance can be used to identify it. A pure substance is an element or a compound, not a mixture.
What is a good reason for knowing chemical and physical properties?
It gets to a point where it becomes pointless
When looking at a periodic table of elements what do you know by knowing in which column an element appears?
Chemical elements in the same group have similar chemical properties.
How can you tell the difference between physical and chemical properties?
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
How can knowing the formula weights of the elements help you balance the equation?
The molar mass is not needed to balance a chemical reaction.You need to know the chemical formulas of reactants, the possible formulas of products, valences of elements and ions, general principles of chemical reactions, some chemical and physical properties of substances involved in the reaction.
What Homologous series?
A homologous series is a family of organic compounds that: *have the same general formula. *have similar chemical properties and *show a gradual increase in physical properties such as melting and boiling point.
How is knowing the properties of liquids helpful?
Knowing the properties of fuel is very helpful. For eg, if we know its burning temperature and amount of calories produced, we can determine its efficiency to be used as a fuel. also by knowing the properties of viscosity we can determine its rate of flow, how to efficiently use it for the various purposes. Properties help to determine the best use of the liquid and thus increasing efficiency and productivity.
What is the name of a 100000000000000 sided shape?
Knowing its name is not important but what's more important is knowing how to work out its properties.
