When a solution of dithionite ions (s2o42–) is added to a solution of chromate ions (cro42–), the products of the ensuing chemical reaction, which occurs under basic conditions, include soluble sulfite ions and solid chromic hydroxide. this reaction is used to remove cr(vi) from wastewater generated by factories that make chrome-plated metals?

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures

it is b. absorbs thermal energy
