What evidence of chemical change occur in iron rust?
The evidence of chemical reaction in the rusting of an iron nail is a color change. This is due to the formation of iron oxide, which is the reaction between iron and oxygen.
Does chemical changes change in the identity of a substance due to its chemical properties?
no
Why iron tablets were not hard and didnot look like iron at allwhat tablets contained?
the tablets contained the compounds of iron due to which the entire properties of iron transformed.
How come SI and GE have similar chemical properties?
Si and Ge have similar chemical properties due to how close they are on the periodic table. Silicon and GermaniumÊare both metalloids.
Zr and Hf almost show same chemical properties?
Due to lanthanide contraction

What chemical properties of the elements are chiefly due on what?
The chemical properties of the elements are chiefly due to the number and distribution of the outer electrons that they have.

Why does earth behaves like a magnet?
The earth's magnetic properties are due to its molten iron core.
Zr and Hf almost show same chemical properties?
Due to lanthanide contraction
What is the physical changes in matter?
Physical changes in matter are when physical properties are changed. Some physical properties are size and color. When a physical change in matter occurs, the material may have changed size (gotten smaller) due to weathering and erosion. Chemical changes are when the chemical composition of a substnce is changed. For example a chemical change would be iron turning into rust due to the process of oxidation
Is corrode physical or chemical property?
Corrosion is a chemical process where a material reacts with an element (usually oxygen) resulting in a degraded version of the original material. OR the chemical corrosion results in different physical property of the material.
Why does salt exist?
Because sodium and chloride were met and due to their chemical properties the combination was possible.
What should be similarities among homologies?
Homologise have the different molecular masses so can not have the same physical properties, due to same functional group they show same chemical properties but with different rates of reaction.
What are the properties of polytetrafluroethene?
Poly(tetraflurothene) has properties of chemical interness, heat resistance and non-stick qualities. All these properties are due to the strong carbon-flourine bonds in the polymer structure.
