Does anyone have the key to "Student Exploration: Convection Cells"
It's a gizmo.

Draw the more stable lewis dot structure for bro2-

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]

Chortling is used to clean water. another possible atom that would also work is a. sodium b. sulfur c. bromine
