what is the mass of the sample of ammonia, given to two significant figures?
a 0.00019 g b 0.0034 g c 0.19 g d 3.4 g

Iwould go with i'm not positive because i'm dumb that

Ithink it's carbonic acid

Idon’t know what the answer is i wish i could

Van der waals forces are temporary electromagnetic forces established between uncharged atoms. some neutral molecules, when close together, can become temporarily “charged,” as electrons move around the atom. water is a polar molecule, the side of the molecule that the hydrogens bond to being more positive, and the opposite side bound to the lone pairs of electrons being more negative. this means that it participates in dipole-dipole interaction (non-polar exhibits dispersion forces), and it has the capacity for hydrogen bonding.
