Answer:
1837 electrons.
Explanation:
1837 electrons have the same mass as 1 proton.
Answer:
Solar power
Or in some cases, from heat from the sun. ... Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity.
Explanation:
Answer:
See explanation
Explanation:
We have to remember that for any <u>equilibrium expression constant</u> we can use the general reaction:
With a equilibrium expression:
We have to <u>divide products by reagents and use the coefficient (in the balanced reaction) as exponents</u>. So:
The reaction is <u>already balanced</u>. So, we can write the equilibrium expression:
In this case, all the compounds have <u>gaseous state (g)</u>. So, we can change the concentration ([]) by the <u>pressure of each compound</u>:

<u>Answer:</u> The energy of photon is
<u>Explanation:</u>
The relation between energy and wavelength of light is given by Planck's equation, which is:
where,
E = energy of the light = ?
h = Planck's constant =
c = speed of light =
= wavelength of photon = 0.122 m
Putting values in above equation, we get:
Hence, the energy of photon is
The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized
