Answer:
Kp=Kc *(RT)+-3
Explanation:
The relation between Kp and Kc is given below:
Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant , R = 0.082057 L atm.mol⁻¹K⁻¹
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:
Δn = (0)-(2+1) = -3
Thus, Kp is:
Kp=Kc *(RT)+-3
Answer:
Elements: F, Cl, Br, I, At
Explanation:
Hi there,
When you are trying to find the valence electrons for an element, look at the last number of the electron configuration.
For example, if you want to find the number of valence electrons of Carbon (C), you notice that the electron configuration is<u> 2 - 4.</u>
We know that this element has four valence electrons because the last number in its electron configuration is 4.
For your question, simply find all of the elements that have the number 7 as the last number on its electron configuration on the periodic table.
Hope this answer was helpful. Cheers.
Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O)
Answer:
Explanation:
According to the law of definite proportions, particles in a compound combine by a defined stoichiometric ratio. This ratio is also calculated in terms of moles.
In order to find the ratio between the particles in a compound, we need to find the molar ratio of each species.
Notice that the ratio between the number of moles of zinc to the number of moles of nitrogen is:
This means if we are given 1 zinc ion, we expect to have a total of 2 nitrogen atoms. Therefore, x = 2.
