This structure forms a ionic bond, which are generally stronger than covalent bonds. All of the other choices are covalent.
I believe the answer is B.
I believe the answer would be D.
Sodium loses an electron and chlorine gains an electron.
The answer to this question is C.
The answer would be B, double covalent bond... I would think.
because ionic molecules are not soluble in oil
polar molecules are soluble in water
nonpolar molecules are not soluble in water
and metals are not soluble neither in water nor in oil
That is because all combustion reactions produce CO2 and H2O due to a reaction of a compound containing C H or C H and O with O2.
Just in case: If they show you a similar reaction but with CO instead of CO2, it is an incomplete combustion reaction.
the formula would be mgso4
away from the curb
the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
