Identify the type of knowledge. 1. Follows the NOTTUS model completely.

2. Follows parts of the NOTTUS model, but ignores relevant information.

3. Follows parts of the NOTTUS model, but not enough information exists to complete it.

4. Does not follow the NOTTUS model at all.

P. S. Use simple terms, I'm only in 7th grade.

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?
