light that allows Elsa to see herself?
Light waves are refracted by the surface of the object bending the light and allowing Elsa to see herself.
O Light waves are diffracted by the surface of the object creating shine that allows Elsa to see herself
Light waves are absorbed by the surface of the object allowing Elsa to see herself.
O Light waves are reflected from the surface back into Elsa's eyes allowing her to see herself.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
