Answer:
Explanation:
The formation of ammonia that occurred by the reaction of nitrogen and ammonia is expressed as:
⇄
where;
The reactants are:
Hydrogen and nitrogen
The product is ammonia.
For the reaction, the equilibrium constant can be expressed as:
From the equilibrium constant conditions, the formation of ammonia and its decomposition due to its reversible reaction back to hydrogen and nitrogen are equal. It implies that the rate of the forward reaction is also equal to that of the backward reaction.
Thus, during when equilibrium is obtained;
Hydrogen, Nitrogen, and Ammonia are present.
Answer: for question 4, the answer would most likely be movement of air, water and rock
Explanation:
Answer:
7.22*10^24 molecules
Explanation:
Since one mole has 6.02*10^23 you'd multiply that number by 12
that equals 7.224*10^24 but you need sig figs
Answer
The mole ratio is 1:1
The molar mass of potassium hydrogen phthalate (C8H5KO4) is 204.22g/mol
The mass of C8H5KO4 is 0.43g
The no of moles of C8H5KO4 = mass/molar mass
No of Moles of C8H5KO4 = 0.000210557242mol
From Mole ratio the no of mole of NaOH that reacted with C8H5KO4 0.000210557242
Therefore, molaroty of NaOH is mole of NaOH/the Volume in L
Molaroty if NaOH = 0.000210557242/0.02411 = 0.08733M
Answer:
250cm³ de disolución se deben preparar
Explanation:
El porcentaje volumen volumen (%v/v) se define como el volumen de soluto -En este caso, H2O2- en 100cm³ de disolución.
Se desea preparar una solución que contenga 20cm³ de H2O2 por cada 100cm³
Como solamente se cuenta con 50cm³ de H2O2, el volumen que se debe preparar es:
50cm³ H2O2 * (100cm³ Disolución / 20cm³ H2O2) =
<h3>250cm³ de disolución se deben preparar</h3>
