I'm pretty sure its B or C. Sorry, hope this helped some....??
It would be C, 6.2 x 10^23.
Avogadro's number, or, the mole, is 6.02 x 10^23. Although the grams and molar mass of an element may be different, every element must have the same amount of atoms to obey avogadro's number.
Answer:
Explanation:
a ) If N₂(g) and 3H₂(g) is added to the system , 2 moles of additional ammonia will be produced .
b ) If pressure is decreased , less amount of ammonia will be formed, because forward reaction reduces the pressure. So, reaction will take place in reverse direction.
c ) Keq = [ NH₃ ] ² / [ N₂ ] [ H₂]³
d ) Substituting the given values in the equation ,
Keq = [ 6M ] ² / [ 3M] [ 4M]³
= 36 / 3 x 64 M⁻²
= 18.75 x 10⁻² M⁻² .
The physical properties of matter are going to be appearance,texture, density. hope that helped
