Answer:
Heat lost to the surroundings
Heat lost to the thermometer
Explanation:
All changes in heat, or energy, can be explained. Many of the reactions or changes we see in the world involve the conversion of energy. For example as we heat up a substance (eg. water), the amount of energy we put in should give us an exact temperature. However, this is a "perfect world" scenario, and does not occur in real life. Whenever heat is added to a substance like water, we always need to account for the energy that is going to be lost. For example, heat lost to evaporation or even the effect of measuring the temperature with a thermometer (the introduction of anything including a thermometer will affect the temperature).
Answer: The reaction does occur.
Explanation: For the reaction of aqueous strontium sulfide and aqueous copper(II) sulfate, the reaction follows:
This reaction is a type of precipitation reaction.
The precipitate formed is CuS which is black in color.
Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require = 2 moles of 
Thus 0.06 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 moles of give = 1 mole of 
Thus 0.06 moles of give =
of
Mass of 
Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.
