Answer:
Table salt (the iodine isn't important) consists of much smaller particles than rock salt and therefore has a much higher ratio of surface area to mass. Since chemical reactions occur at surfaces,the smaller table salt particles will dissolve far more quickly than the larger rock salt.
Explanation:
Answer:
of heat energy will be released
Explanation:
Balanced reaction-
According to balanced equation, moles of produces 1 mol of to release 46.17 kJ of heat.
Molar mass of = 2.016 g/mol
Number of moles = (mass)/(molar mass)
So, 28 kg of = 28000 g of
= moles of
= moles of
So. moles of react to release heat or of heat
