1.20g of silver was deposited when 1.60 amperes of current where passed through silver trioxonitrate {v} and copper.{ II} chloride solution connected in series calculate {a} mass of copper deposited during electroleysis ( b) the time taken for the deposition of silver metal

Which of these is an intensive property of a substance

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.

Awhite powder is added to a solution. the images show observations made before the powder is added, just after the powder has been added, and a little while later. (the liquid in the small beaker is phenol red solution.) what evidence shows that a chemical change has taken place?
