Suppose an unknown substance has a melting temperature of 1,200 degrees celsius and a density of 16.7 g/cm3. however, the different individual atoms that make up the element have very different melting temperatures and densities. which is the unknown substance most likely?
a) solution
b) compound
c) molecule

Option (B) is the correct answer.

Explanation:

As it is given that the melting temperature of substance is 1200 degree Celsius and its density is 16.7 .

Since, the temperature is very high and no solution or molecule exists at such a high temperature.

Whereas a compound is defined as the substance which contains two or more different elements which chemically combine together in a fixed ratio by mass.

Compounds in the form of alloys have high melting temperature.

Thus, we can conclude that the given unknown substance is most likely a compound.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
