To cook a steak to medium-rare, it needs to have an internal temperature of 135

fahrenheit. a lower internal temperature will undercook the steak.
write an inequality that is true only for temperatures (t) at which a steak will be undercooked.

The three types is stress that act on earths rocks are compression, tension, and

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?
