Jamal has two identical metal cans. He lifts his foot in the air and slowly brings it down to put force on one of the metal cans. After Jamal lifts his foot back into the air, the metal can is bent in the middle.

Jamal is going to use his foot in the same way to put force on the second metal can. What will most likely happen if Jamal moves his foot faster as he brings it down on the second metal can?

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
