The atomic number of Nitrogen is 7 because Nitrogen has 7 protons. The seven protons attract 7 electrons in the ground state.
If the atom had fewer or more than 7 protons the atom would not be Nitrogen.
The mass of the atom is the sum of protons and neutron. so
p + n = mass ( protons (p) and neutrons(n) both have an atomic mass of one
7 + n = 15 subtract 7 from both sides
<span>7−7+n=15−7</span>
n = 8
Answer:
Value of equilibrium constant is 0.0888
Explanation:
Both and are gaseous. Hence equilibrium constant depends upon partial pressures of and .
Initially no and were present.
Hence mole fraction of and at equilibrium can be calculated from coefficient of and in balanced equation.
Mole fraction of = (number of moles of )/(total number of moles of and ) =
Let's assume both and behaves ideally.
Therefore partial pressure of , and P_{CO_{2}}= x_{CO_{2}}.P_{total}
Where x represents mole fraction
So,
A - convection
B - conduction
C - radiation
D - convection
Spices
Herbs are the leaves.
Vegetables are the seeds.
Fruits are the seeds.
So spices are the only option left.
