B - true
C - false
In chemistry there is a principle that polar compounds are soluble with other polar compounds and non-polar compounds are mutually different.
Thus, sodium chloride is an ionic salt (polar) so it is not soluble in the benzene (non-polar) covalent compound, but it is soluble in water that is polar.
The ionic compounds will be soluble in polar solvents and not soluble in non-polar solvents, regardless of whether they are organic or inorganic.
THE EXTRACTION OF METALS FROM THEIR RESPECTIVE ORES IS KNOWN AS METALLURGY.
THE DIFFERENT PROCESS ARE :- ROASTING, CALCINATION, FROTH FLOTATION AND MGNETIC SEPARATION.
Two is wrong the rest are right
Answer:
Explanation:
Hello,
In this case, we employ the combined ideal gas law in order to understand the volume-gas-pressure behavior as shown below:
Hence, solving for the final pressure P2, we obtain (do not forget temperature must be absolute):
Best regards.
Answer:
This is considered a hypothesis because it hasn't been confirmed. It is just a guess.
Explanation:
A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. Law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. However, Newton's law doesn't explain what gravity is, or how it works.
