Consider the temperature versus time graph below. A graph of temperature versus time, with time in minutes as the horizontal axis and temperature in degrees Celsius as the vertical axis. 5 sections of line are labeled: 1 from 0 minutes, negative 80 degrees to 1, negative 40. 2: from 1, negative 40 to 3, negative 40. 3: from 3, negative 40 to 7, 360. 4: from 7, 360 to 15, 360. 5: from 15, 360 off the top at the chart at 18 minutes.

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?
