Because their is no motion in them their for they can not do anything but just sit their I hope I helped u if not I’m so so sorry
To form CuO - 100 g of Copper reacts with 25 g of Oxygen
then amount of CuO formed - 125 g
Since excess oxygen is provided, Copper is the limiting reactant. Then Copper is completely consumed during the reaction and amount of product formed depends on the amount of Copper used.
So if 100 g of Copper makes up 125 g of CuO
Then 140 g of Copper will form - 125/100 x 140 = 175 g of CuO
Answer:
Theoretical yield = 3.75g
Explanation:
Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:
Percent yield = Actual Yield / Theoretical Yield * 100
In the problem, your actual yield was 3-00g.
Percent yield is 80.0%.
Solving for theoretical yield:
80% = 3.00g / Theoretical yield * 100
Theoretical yield = 3.00g / 80.0% * 100
<h3>Theoretical yield = 3.75g</h3>
<u>Answer:</u> The wavelength of spectral line is 656 nm
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant =
= Final energy level = 2
= Initial energy level = 3
Putting the values in above equation, we get:
Converting this into nanometers, we use the conversion factor:
So,
Hence, the wavelength of spectral line is 656 nm
