The reaction quotient of the reaction is 7.00238.
From the question.
BrCl2 is 0.004150
Br is 0.003660
Cl is 0.00067210
Q={BrCl2}/{Br}{CL2}
Q=0.004150^2/(0.0036660)(0.00067210)
Q= 7.00238
<h3>What is equilibrium?</h3>

Mixtures
they are not elements or pure substances nor are they compounds
Mg3(PO4)2 - the molar mass would be 262g/mol, which is 100%
Atomic mass of Mg is 24, since we have 3Mg we multiply by 3 and get a mass of 72
262 : 100% = 72 : x%
x = 72*100 / 262
x = 27.5%
And do that for every element — get the molar mass of P and multiply by 2, use a ratio, and get the molar mass of O and multiply by 8 and use ratios :)
