Hello! i am working on some homework and came across this question, which completely confuses me for various reasons. experimental evidence suggests that the nitrogen atom in ammonia, nh3, has four identical orbitals in the shape of a pyramid or tetrahedron. a). draw an energy-level diagram to show the formation of these hybrid orbitals. (hint: no electron promotion is required). b). name the type of hybrid orbitals found in nh3. of the four hybrid orbitals on the n atom, how many will take part in bonding? explain.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
