From the calculation, there are 1.5 g of water produced in the reaction.
<h3>What is an equation?</h3>
An equation shows the chemical transformation that takes place in a reaction vessel. In this case, the equation is; C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O.
Now;
Number of moles of glucose = 2.5g/180 g/mol = 0.014 moles
Since 1 mole of glucose produces 6 moles of water
0.014 moles of glucose produces 0.014 moles * 6 moles/ 1 mole
= 0.084 moles
Mass of water produced = 0.084 moles * 18 g/mol = 1.5 g of water

It would be Cu(NO3)2. The NO3 has a negative charge. Copper has a positive 2. In order to have a stable compound, you would need 2 NO3s, which is why there is a 2 outside of the NO3. I hope this helps.
Answer:
Observation 2 is a result of silver ions changing their oxidation state.
Explanation:
Silver is reduced and forms silver precipitate. Observation 1 is a result of coppe being oxidized and forming copper nitrate
