Answer: The difference between the electronegativity or (∆EN) of two different atoms indicates the type of bond created.
Explanation: For ionic bond compounds the difference between their electronegativity is 1.7 or greater. Covalent bond compounds have a difference of 0.4 but not greater than 1.7 on their electronegativity.
D-toxicity :)
hope this helps
You don't "turn" it into energy; petroleum HAS stored energy (chemical energy).However, you can turn it into ANOTHER TYPE OF ENERGY; usually this is done by burning the petroleum, and using it to drive machinery.
Since burning fuels is wasteful (the efficiency is limited, in theory, to the Carnot efficiency of a heat engine), other options are being explored, such as chemical reactions in a fuel cell. But such technology is not yet used on a large scale.
Answer:
The chemical name for the compound formula NaCl is sodium chloride.
Answer:
B
Explanation:
