This is a reduction reaction as the oxide(oxygen) is taken away from the metal =]
This information confirms that temperature and solubility are related. The higher the temperature is, the more soluble.
Explanation:
the answer is that prokaryotic cells are not multicellular
Answer:
Explanation:
You realize that C2H5OH releases -1277.3kJ/mol. We need to convert this to the amount based on the question. We that 22.52g of C2H5OH = 0.48884 mol.
This means that it will release (-1277.3)(0.48884) = 624.40 KJ of heat will be released. Note the negative sign is not necessary here (I think) because it says how much is released and not the change in heat of the system so it should be positive.
