Answer:
We need 0.095 moles of ethanol
Explanation:
Step 1: Data given
Number of moles water = 0.095 moles
Step 2: The balanced equation
CH3CH2OH + O2 ⇒ H2O + CH3COOH
Step 3: Calculate moles of ethanol
For 1 mol ethanol we need 1 mol oxygen to produce 1 mol water and 1 mol acetic acid
For 0.095 moles water, we need 0.095 moles ethanol and 0.095 moles oxygen
We need 0.095 moles of ethanol
Answer:
17.6%
Explanation:
%age yield is = actual yield /percentage yield ^100
Mass is measured by using a balance
The working equation for this is written below:
E° = 0.0592logK/n
So, we have to know the value of n first which represents the number of moles electron in the reaction. We cannot answer this because we are not given with the reaction. However, just suppose the reaction is:
Cu⁺ + 2e⁻ --> Cu
Then, n=2. Continuing,
E° = 0.0592log(6.47×10⁵)/2 =<em> 0.172 V</em>
