Answer:
2Al+1.5O2→Al2O3
Thus, 2 mol of Al combine with 1.5 mol of oxygen to form 1 mol of Al2O3.
2 mol of Al corresponds to 2×27=54 g.
Thus, the weight of Al used in the reaction is 54 g.
Heat pumps most do work on a refrigerant in order to reverse the normal flow of thermal energy.

A nuclear hypothesis is a model created to clarify the properties and practices of iotas. Similarly as with any logical hypothesis, a nuclear hypothesis depends on logical proof accessible at In compound responses, molecules join with each other in simple, charged particles (like electrons) that movement through space emit vitality.
Answer:
endothermic reaction
Explanation:
This is because it absorb heat from the surrounding which is required to break the bond hold it together hence as it absorb heat from the surrounding the temp of surrounding decrease.
