Calculate the enthalpy change (AH) in kJ for the following reaction.
2Al(s) + Fe2O3(s) → 2Fe(s) + Al2O3(s)
Use the enthalpy changes for the combustion of
aluminum and iron:
2Al(s) + O2(g) →→ Al2O3(s)
Al,,() AH = -1669.8 kJ
2Fe(s) + O2(g) → Fe, c(s) AH = -824.2 kJ

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary

they are made of gases.

they have a spherical shape.

they make energy through fusion.

have a great day because if you dont you and i will be sad

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
