Answer:
ΔHrxn = [(1) -1675.5 ( kJ/mole) + (2) 0 ( kJ/mole)] - [(1) -824.3 ( kJ/mole) + (2) 0 ( kJ/mole)]
Explanation:
ΔHrxn = 2ΔHf (Al₂O₃) - ΔHf (Fe₂O₃)
Remember that for pure elements in their standard state of temperature and pressure by definition their standard heats of formation are zero.
ΔHrxn = 2(-1675.7) - (-824.3) kJ/mol
ΔHrxn = 2527 kJ/mol
Answer:

It belongs to kingdom protista
It does not have membrane bounded organelles
Explanation:
Answer:
carbon molecules share their 4 valence electrons through single, double, and triple bonds.
Explanation:
I think you meant ionic bonds not lonic bonds
i think it’s B. a hydrocarbon reacts with oxygen
if i’m correct, a combustion reaction is anything that’ll give a reaction
Answer:
The thermal energy, orheat, of an object is obtained by adding up the kinetic energy of all the molecules within it.Temperature is the average kineticenergy of the molecules.
