There are two equations given in the question. The type of reaction shown can be easily judged, if one takes a closer look at the equations.
1. <span>Ba(ClO3)2(s) ----> BaCl2(s) + 3O2(g) ------- Redox
2. </span><span>CaO(s) +CO2(g) ----> CaCO3(s) -------- None.
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>
1. Solubility
2. Heat 100g of water to 35 degrees C. Add 37 grams of mystery salt.
3. If all the salt dissolves, it's KCl. If not, it's KNO3.
The answer is B I’m pretty sure
The first law of thermodynamics states the conservation of energy and heat where the <span>total energy in an isolated system may be transformed into another, but never created or destroyed. If 314 J of energy was released to the room, then also 314 J of energy was also removed from food in that refrigerator assuming it is an isolated system. </span>
