Dalton assumed that all atoms of the same element were identical in all their properties. Explain why this assumption is not val
jeka57 [31]
This assumption is not valid because, there are some elements which exist in two or more forms;  they have the same atomic number but differ in their mass number, which meas that they possess different number of neutrons. These type of element are called isotopes. Isotope have the same atomic number  and similar physical and chemical properties but they have different number of neutrons and therefore possess different masses.

A chemistry student needs 60.0 g of tetrahydrofuran for an experiment. By consulting the CRC Handbook of Chemistry and Physics,
Evgen [1.6K]

Answer:

67.492cm^3

Explanation:

To get the volume of tetrahydrofuran needed, what the student need to do is to apply mathematical calculations.

We know quite well that to obtain the volume of a substance, given the mass of the substance and the density of the substance is possible.

The volume of the substance is simply the mass of the substance divided by the density of the substance.

This is thus volume = mass/density

The mass given is the question is 60g while the density given is 0.889g/cm^3

The volume = 60/0.889 = 67.492cm^3

All organic compound soluble in WATEe and conduct electrically ​
Delvig [45]

No

Explanation:

Not all organic substances are soluble in water and will not conduct electricity. Only polar organic compounds are soluble in water and will conduct electricity.

  • The general rule of solubility is that like dissolves likes.
  • Polar compounds will only dissolve other polar compounds too. Water is a polar solvent.
  • Non-polar compounds will only dissolve in non-polar compounds too.
  • Since water is a polar organic compound, only polar organic compounds will dissolve in it.
  • Not all organic compounds are polar.
  • When a compound dissolves in water, it produces ions that makes it able to conduct electricity.
  • Fats and oil are insoluble in water
