Answer:
I) Change in solubility
II) Change in boiling point
III) Change in colour
Explanation:
A chemical change involves formation of new products and is not reversible.
So, once two liquid solutions are mixed and a chemical change takes place, the new product will have the following:
- a new solubility rate, i.e it will dissolve at a rate different from the two liquid solution
- a new boiling point i.e it takes a new point at which its molecules liberate to yield vapour
- a new colour might be detected, as the individual solution each has its own colour
Answer:
Vacuum: space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there It is a condition well below normal atmospheric pressure and is measured in units of pressure (the pascal).-the internet gave me this answer so..

Answer: Heat associated with the formation of 100.0 g of carbon dioxide is 1563.2 kJ.
Explanation:
Reaction equation will be as follows.
;
= -11018 kJ
Mass of
= 100 g
Hence, moles of
present will be calculated as follows.
No. of moles = 
= 
= 2.27 mol
Therefore, heat produced by 2.27 mol for the given reaction will be calculated as follows.

= 1563.2 kJ
Thus, we can conclude that heat associated with the formation of 100.0 g of carbon dioxide is 1563.2 kJ.
