Elements are made of one type of atoms. Elements have characteristic symbols for their identification.
1) Bi(NO₃)₃ - this is made of 3 elements - Bismuth , Nitrogen and oxygen
2) KOH - made of 3 elements - potassium (K), oxygen and hydrogen
3) NaClO₃ - made of 3 elements - sodium (Na), chlorine and Oxygen
4) Al₂S₃ - made of 2 elements - Aluminium and sulphur
we are asked for the formula with 2 elements , correct answer is 4)
D would be correct (i did this Assessment today)<span />
Answer:
the density of the sample - the melting point of the sample
Explanation:
Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.
For example,
Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.
Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.
