Answer:
The position of equilibrium will move to the right
Explanation:

The enthalpy of reaction is positive, so the reaction is endothermic and we can consider the heat as a "reactant".
We can rewrite the equation as

According to Le Châtelier's Principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.
In this problem, the stress is the increase in temperature (addition of heat).
If we add heat, the position of equilibrium will move to the right to get rid of the heat.
Answer: an ice pack getting cold (due to ammonium nitrate dissolving in water inside the pack)
Explanation:
Endothermic reactions: These are the reactions in which energy is required in the reaction. The energy of the products are more than the energy of the reactants.
Exothermic reactions: These are the reactions in which energy is released in the reaction. The energy of the products is less than the energy of the reactants.
a) water droplets condensing on a soda can on a hot summer day : As the gaseous molecules are changing into liquid phase, energy is released and is exothermic
b) an ice pack getting cold (due to ammonium nitrate dissolving in water inside the pack) : As the temperature is decreasing , energy is absorbed by the surroundings and thus is endothermic
c) thermite reaction between iron(III) oxide and aluminium (spectacular flames are observed) : As flames are produced, the energy is released and thus is exothermic
d) freezing water to make ice cubes : As the liquid molecules are changing into solid phase, energy is released and is exothermic
Answer:
1037.56 mph
Explanation:
We are told the distance around the earth which is the circumference is 40075 km.
Converting to miles gives 24901.451 miles
Formula for speed = distance/time
Time for one rotation is 24 hours.
Thus, speed = 24901.451/24 = 1037.56 mph
There are 21.36 grams of SO3 produced.
I hope this helps. :)
