<u>Answer:</u> The wavelength of an electron is
<u>Explanation:</u>
To calculate the wavelength of a particle, we use the equation given by De-Broglie's wavelength, which is:
where,
= De-Broglie's wavelength = ?
h = Planck's constant =
m = mass of electron =
v = velocity of electron =
Putting values in above equation, we get:
Hence, the wavelength of an electron is
Answer:- g of carbon dioxide.
Solution:- The balanced equation for the combustion of methane is:
There is 1:1 mol ratio between methane and carbon dioxide. Grams of methane are converted to moles and then using mol ratio we get the moles of carbon dioxide that could further be converted to grams. The calculations are shown as:
=
So, complete combustion of given amount of methane gives .
