None
it is a form of electromagnetic radiation, meaning it does not have any protons or neutrons
Answer:
La teoría de Brønsted-Lowry es una teoría sobre las reacciones ácido-base que fue propuesta independientemente por Johannes Nicolaus Brønsted y Thomas Martin Lowry en 1923.
2C₄H₁₀ + 13O₂ = 8CO₂ + 10H₂O
C₄H₁₀→5H₂→2.5O₂→2C₄H₁₀→5O₂
8C→8O₂
5+8=13O₂
At combustion of butane the carbon dioxide and water are formed.
The carbon dioxide and water is products of the complete combustion of hydrocarbons.
Answer:
v = 301.62 km/s
Explanation:
Given that:
The work function of the magnesium = 3.68 eV
Energy in eV can be converted to energy in J as:
1 eV = 1.6022 × 10⁻¹⁹ J
So, work function = ![3.68\times 1.6022\times 10^{-19}\ J=5.8961\times 10^{-19}\ J](https://tex.z-dn.net/?f=3.68%5Ctimes%201.6022%5Ctimes%2010%5E%7B-19%7D%5C%20J%3D5.8961%5Ctimes%2010%5E%7B-19%7D%5C%20J)
Using the equation for photoelectric effect as:
Also,
Applying the equation as:
Where,
h is Plank's constant having value
c is the speed of light having value
m is the mass of electron having value ![9.11\times 10^{-31}\ kg](https://tex.z-dn.net/?f=9.11%5Ctimes%2010%5E%7B-31%7D%5C%20kg)
is the wavelength of the light being bombarded
v is the velocity of electron
Given,
Thus, applying values as:
![\frac{1}{2}\times 9.11\times 10^{-31}\times v^2=6.31047619\times 10^{-19}-5.8961\times 10^{-19}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctimes%209.11%5Ctimes%2010%5E%7B-31%7D%5Ctimes%20v%5E2%3D6.31047619%5Ctimes%2010%5E%7B-19%7D-5.8961%5Ctimes%2010%5E%7B-19%7D)
![\frac{1}{2}\times 9.11\times 10^{-31}\times v^2=0.41437619\times 10^{-19}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctimes%209.11%5Ctimes%2010%5E%7B-31%7D%5Ctimes%20v%5E2%3D0.41437619%5Ctimes%2010%5E%7B-19%7D)
![v^2=0.0909717212\times 10^{12}](https://tex.z-dn.net/?f=v%5E2%3D0.0909717212%5Ctimes%2010%5E%7B12%7D)
v = 3.0162 × 10⁵ m/s
Also, 1 m = 0.001 km
So, v = 301.62 km/s
