3. If the sun heats my car from a temperature of 20.0 C to a temperature of 55° C, what will the pressure inside my car be? Assume the pressure was initially 570 mmHg.
FORMULA:

Write the complete balanced equation for the reaction between lead (iv) oxide (pbo2) and water (h2o).

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?
