A40.0 l balloon is filled with air at sea level (1 atm @ 25 oc). it is then tied to a rock and thrown into a cold lake and it sinks to the bottom! when it reaches the bottom of the lake the temperature is 4.0 oc and the pressure has increased to 11 atm. what will the new volume be? a. 0.295 l b. 3.38 l c. 3.91 l d. 187.6 l

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?
