The theoretical mass of silver that will be produced is calculated as follows
write the reaction equation
Cu + 2Ag(No3) ---> 2Ag + Cu(NO3)2
calculated the moles of each reagent
moles =mass/molar mass
Cu = 6.51g/63.5g/mol= 0.103 moles
Ag(NO3)2 = 28.4 g/169.87g/mol = 0.167 moles
Cu is the limiting reagent therefore the moles Ag= 2 x0.167 = 0.334 moles
mass = moles xmolar mass
0.334mol x 107.87g/mol = 36.02 grams
The temperature at which the oven it set it should be.
Keto-enol tautomerism
<u>Explanation:</u>
Phenolphthalein is an indicator (C₂₀H₁₄O₄), which is utilized to find the volume in the titration of acid and base, Depending on the pH value the indicator, changes its color from colorless in acids to pink in basic medium.
It is a weak acid, losses a (H⁺) proton in solution, that is colorless, whereas the corresponding anion is pink in color.
This change in color of the molecule is not only defined by the addition of a base or an acid, but also with the structure of the indicator, which leads to tautomerism called as keto-enol tautomerism. If a molecule has 2 (-OH) hydroxyl groups as well as 1 (C=O) carbonyl group, exhibit an equilibrium among both the groups. Because of this change, structure of the indicator changes and so color also changes.
Na, Ba, Cs and Ni are metals.
Answer:
I got 1.14 mol So3 as the answer
hopefully if this could help
