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?

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
