The reaction is at equilibrium at 1,000 k. the equilibrium constant of the reaction is 3.90. at equilibrium, the concentrations are as follows. [co] = 0.30 m [h2] = 0.10 m [h2o] = 0.020 m what is the equilibrium concentration of ch4 expressed in scientific notation? .0059 5.9 x 10-2 0.059 5.9 x 102

Answer : The correct option is,

Solution : Given,

Equilibrium constant = 3.90

Concentration of = 0.30 M

Concentration of = 0.10 M

Concentration of = 0.020 M

The balanced equilibrium reaction will be,

The expression for equilibrium reaction will be,

Now put all the given values in this expression, we get the concentration of methane.

Scientific notation : It is the way of representation or writing the very large and the small number. In scientific notation, a number is written when a number between 1 and 10 is multiplied by the power of 10.

Therefore, the equilibrium concentration of methane is,

c. 4.54 x 10–12 j happens to be correct

answer is: empirical formula is tl₂o. if we use 100 grams of compound, tha:

m(tl) = 96.2%  · 100 g ÷ 100%.

m(tl) = 96.2 g.

n(tl) = m(tl)  ÷ m(tl). n(tl) = 96.2 g  ÷ 204.4 g/mol.

n(tl) = 0.47 mol. m(o) = 3.77 g. n(o) = m(o)  ÷ m(o). n(o) = 3.77 g  ÷ 16 g/mol. n(ag) = 0.235 mol. n(tl) . n(o) = 0.47 mol : 0.235 mol /0.235. n(tl) . n(o) = 2 : 1.

m(tl₂o) = 204.4 g/mol  · 2 + 16 g/mol = 424.8 g/mol.

m(compound) = 456. 8 g/mol - 424.8 g/mol = 32 g/mol ( 2 oxygens); tl₂o₃.
