Heptane, C7H16, is an organic hydrocarbon that is nonpolar, thus it would not be attracted to a charged rod.
no.
Due to electrostatic induction
If charge on the balloon is induced due to the charge of the glass rod then there will be opposite charge and so balloon gets attracted by the rod. Unlike charges do attract each other
because they have a positive and negative end
When there attracted to the charged wand they are polar.
no.
Charged rod and an uncharged metal object attract each other because free electrons in metal are either attracted or repelled by the charged rod. If the rod is positively charged then free electrons are attracted towards it and both objects attract each other. If the rod is negatively charged then free electrons are repelled by it and positive ions are attracted by the rod and both objects attract each other.

paper sticking to a charged CD water attracted to an ebonite rod
because they have a positive and negative end
A glass rod that is charged usually attracts the small bits of paper placed near it because it is usually electrostatically charged.
it is becuase when a glas rod charged by rubbing a cloth it aquires positive charge and when a plastic straw is charged by rubbing a cloth it aquires negative charge. Therefore a charged glass rod attracts a charged plastic rod.
The glass rod aquires static electricity.the paper bits are negatively charged and the glass rod is positively charged.when it battracts the paper ,the both aquire like charges due to which they both are repelled.
If you rub an acetate rod with a cloth electrons are transferred from the rod to the cloth and the rod becomes negatively charged and the cloth becomes positively charged.
Uncharged means that there are an equal number of protons and electrons. When the negative rod is held near the neutral metal ball, the electrons from the metal ball repel from the electrons on the rod bringing the protons closer to the rod causing the metal ball to be attracted to the negatively charged rod. It's called charging by induction.
