It is polar because it's asymettrical, the O has a slight negative charge. But if H2O had a different structure like this H-O-H this would be non polar, it would then be symmetrical
Answer:
Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. So the volume would increase
Answer:
Explanation:
Hello,
For the given chemical reaction:
Whose heat of reaction is 464.8 kJ/mol which means that energy is absorbed due to the chemical reaction, we can compute the moles of calcium carbide via the following relationship:
Then, since the molar mass of calcium carbide is 64 g/mol, the yielded mass turns out:
Best regards.
The answer is c hope i helped
