No. Usually, the second compound is negitive.
The polarity of a compound can be irrelevant to its naming or molecular formula. In cases of a metal+nonmetal as in NaCl and FeO the first elements are positive ions. Covalently bonded H20 has an electronegative oxygen (and dipole moment), again it is listed second. Lastly. there are also diatomic molecules such as O2 and N2 which do not follow the statement either.
No. Usually, the second compound is negitive.
true
If you mean Br2, it is a compound.
false because a compound has to have two elements to become a compound so if it's just one element it's just a element.

positive 49 Because a negative times a negative is a positive. -7*-7=49. positive * positive = positive negative * negative= positive positive * negative = Negative
true
false
Usually yes, the 1st ion is a cation and the second an anion in an ionic compound. I.e. Sodium chloride consists of Na+ bonding to Cl-

The second word tells you the second element and how many atoms there are in the compound. The second word usually ends in IDE.
Niether. Hydrogencarbonate is an ion. It does not exist on its own, but must be combined with a positive ion to form a compound.
The empirical formula of a chemica compound is the simplest positive integer ratio of atoms of each element present in a compound.
No. First of all, aluminum is an element, not a compound. Second, a compound must contain carbon to be considered organic.
