Answer:
Is the fixed number of water molecules present in one formula unit of a substance
Explanation:
When copper sulphate is heated in a china dish, the blue colomed crystal changes to a white powder due to the removal of molecules of water of crystallization
I did this before and i had got an A no it but its been along time tho
Reaction equations contains symbols which show the physical state of the reactants and products.
<h3>What is a chemical equation:</h3>
A chemical equation is an expression that shows the interaction of reactants to yield products. Usually, symbols such as (s), (l), (g), and (aq) are used to show the state of the reactants and products.
The following are the respective meanings of these symbols;
- (s) - solid
- (l) - Liquid
- (g) - gas
- (aq) - dissolved in water

4. 67.6 breaths per minute
65+73+67+71+62=338/5=67.6
^because there are five terms that we added
Answer:
can only be determined experimentally.
Explanation:
In the early days of inorganic chemistry, the structure of complex ions remained a mystery hence the name ''complex''.
These ions appear to have structures that defied accurate elucidation. However, by diligent laboratory investigation, Alfred Werner was able to accurately determine the structure of cobalt complexes. As a result of this, he is regarded as a pathfinder in coordination chemistry.
Hence, the structure of complex ions can only be determined experimentally.
