Here is the full question:
Cu(s) + 4HNO3(aq) -> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
1.000 g copper wire is reacted with 10 mL of concentrated nitric acid (16M). If 0.953 g of copper was actually recovered at the end of the entire experiment, what would be the percent yield?
Answer:
95.30 %
Explanation:
equation for the reaction is given as:
Cu(s) + 4HNO3(aq) -> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
1.00 g of Cu = 
= 0.01574 mol of Cu
10 mL of 16 M HNO3 = 
= 0.16 mol of HNO3
However, from both variables; we can arrive at a conclusion that Cu is the limiting reagent.
therefore % yield = = 4.70 %
Percentage yield = 
Percentage yield = 
%
Percentage yield = 0.953 × 100%
Percentage yield = 95.30 %
Answer:
How do you calculate the average atomic mass of three isotopes?
To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together. Whenever we do mass calculations involving elements or compounds (combinations of elements), we always use average atomic masses
Explanation:
Answer:
B. CO + H₂O → H₂ + CO₂
Explanation:
Redox reaction -
It is the type of reaction , where the process of oxidation and reduction takes place simultaneously , is known as a redox reaction .
Oxidation refers to the addition of oxygen atom or the removal of hydrogen atom .
And ,
Reduction refers to the addition of hydrogen atom or the removal of the oxygen atom .
From the options given in the question , the only reaction , which have both the process of oxidation as well as reduction , is -
CO + H₂O → H₂ + CO₂
In the above reaction ,
Oxidation process - CO → CO₂ ,
The addition of oxygen atom .
Reduction process - H₂O → H₂ ,
The removal of oxygen atom .
