Answer:
The percent yield of chloro-ethane in the reaction is 82.98%.
Explanation:
Moles of ethane =
Moles of chlorine gases =
As we can see that 1 mol of ethane react with 1 mole of chlorine gas.the 10 moles will require 10 mole of chlorine gas, but only 9.1549 moles of chlorine gas is present.
This means that chlorine gas is in limiting amount and amount of formation of chloro-ethane will depend upon amount of chlorine gas.
According to reaction , 1 mol of chloro ethane gives 1 mol of chloro-ethane.
Then 9.1549 moles of chlorien gas will give:
of chloro-ethane
Mass of 9.1549 moles of chloro-ethane:
9.1549 mol × 64.5 g/mol = 590.4910 g
Theoretical yield of chloro-ethane: 590.4910 g
Given experimental yield of chloro-ethane: 490.0 g
The percent yield of chloro-ethane in the reaction is 82.98%.
Answer:
let's do no.3
Na2O+H2SO4 > Na2SO4 +H2O
Al2O3+3H2SO4>Al2(SO4)3+3H2O
the three before the sulphuric acid is such that the equation balances on both ends
...hope this helps
Answer:
Renewable Energy Source. Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source
Reduces Electricity Bills
Diverse Applications
Explanation:
Answer: The energy of a photon with a wavelength of 820 nm is .
Explanation:
Given : Wavelength = 820 nm
Convert nm into meter as follows.
The relation between energy and wavelength is as follows.
where,
E = energy
h = Planck's constant =
c = speed of light =
= wavelength
Substitute the values into above formula as follows.
Thus, we can conclude that energy of a photon with a wavelength of 820 nm is .
The highest value of the ion is the nucleon number. The correct option is a.
<h3>What is nucleon number?</h3>
The mass number of an element is so named because it represents the total number of protons and neutrons in the element.
The total number of protons and neutrons in an atomic nucleus is known as the mass number, also known as the atomic mass number or nucleon number. It is roughly equivalent to the atomic mass expressed in atomic mass units.
In the given ion Q+, the nucleon number has the highest value in the ion
Thus, the correct option is a.
