What physical and chemical properties rare determined by investigating the periodic table?
Physical properties like lustre cannot be determined. Chemical properties like enthalpy values is hard to determine.
What are facts about pure substances?
cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
Do isomers of the same molecule have identical chemical properties?
When two molecules have different configurations but the same atomic composition the two molecules cannot be said to have the same physio-chemical properties. In fact, a simple rearrangement, even with identical chemical formulas, can drastically change the properties of a substance.
Is true or false chemical properties cannot be seen?
Some can, some cannot
Why is slaking of lime regarded as a chemical change?
because new substance is formed in chemical composition & hence they cannot be reversed.
How do chemical and physical properties differ?
chemical properties cannot be determined just by viewing or touching the substance and physical properties can be observed or measured without changing the composition of matter.

What type of property cannot be observed without changing composition of a substance?
a physical property a chemical property; physical properties are properties such as freezing/melting/boiling points
Which of these is an description of chemical property?
Chemical property is evident from a chemical reaction. The chemical properties cannot be determined just by viewing or touching the substance.
Do isomers of the same molecule have identical chemical properties?
When two molecules have different configurations but the same atomic composition the two molecules cannot be said to have the same physio-chemical properties. In fact, a simple rearrangement, even with identical chemical formulas, can drastically change the properties of a substance.
Which type of property cannot be observed without changing the composition of a substance?
Chemical properties cannot be observed without changing its composition. ie: oxidation numbers Physical properties are properties such as melting point and boiling point. All that is needed to observe these are by placing the compound in a melting point apparatus etc.
What happen when you change the chemical property of aluminium?
The chemical properties cannot be changed; only after a chemical reaction the products have new chemical properties.
Is true or false chemical properties cannot be seen?
Some can, some cannot
What explains the properties of metals?
All the properties of metals are the result of their electron configuration, in which they have between one and three valance electrons and therefore tend to lose electrons when they engage in chemical reactions.
Can chemical properties cannot be observed without changing the substance?
yes
Why is slaking of lime regarded as a chemical change?
because new substance is formed in chemical composition & hence they cannot be reversed.
