When a silver goblet tarnished in the presence of hydrogen sulfide (and oxygen), 2.30 moles of silver sulfide formed. How many moles of silver was consumed?
To find out how many moles of silver were consumed, we first need to determine the mole ratio of silver sulfide to silver in the chemical reaction.
The balanced chemical equation for the reaction of silver with hydrogen sulfide is:
Ag + H2S -> Ag2S
From the balanced equation, we can see that for every 1 mole of silver sulfide (Ag2S) formed, 1 mole of silver (Ag) is consumed.
Given that 2.30 moles of silver sulfide were formed, this means that 2.30 moles of silver were consumed in the reaction.
