Why are metals good conductors of heat? O A. The free-moving electrons transmit heat quickly.
B. The malleable atoms slide past each other, transmitting heat.
O c. The formation of alloys allows a path for heat to travel.
O D. The ductility allows heat to move along an edge quickly.

If the same amount of cacl2 is added to equal volumes of water and maple syrup, which will have the higher temperature?

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?
