If the precipitate of CaSO4 was weighed before all of the
water has evaporated, therefore this will lead to a miscalculation on the
number of moles of CaSO4. During the calculation, the mass of the water will be
included hence there will be higher number of moles than what is correct.
The Inclosure Acts, which use an old or formal spelling of the word now usually spelt "enclosure", cover enclosure of open fields and common land in England and Wales, creating legal property rights to land previously held in common.
A standard of measurement system is important because it allows scientists to compare data and communicate with each other about their results.
Answer:
See explanation
Explanation:
If heat is given out in a reaction, then that reaction is exothermic. If heat is absorbed in a reaction, then that reaction is endothermic.
Hence, if heat is given out, the reaction is exothermic. The heat given out does work on the surrounding thus the laws of conservation of energy are obeyed.
