An experiment requires 40.0g of ethylene glycol, a liquid whose density is 1.114 g/ml. rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. what volume of the liquid should he use?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

According to the vsepr theory what is the shape of a molecule that has a central atom valence three other items with no lone pairs of electrons

Ablock of aluminum is dropped into a graduated cylinder with an initial volume of water at 75ml and the volumes rises to 90ml. if the block has a mass of 40.5 g what is its density ?
