A flask is initially 0.050 M in NO2 and 0.010 M in N204. What will the equilibrium concentrations be if K = 0.50 for 2NO2(g) N204(9) at the conditions of the flask?
ASAP PLEASE HELP

elements make up everything, and they combine to make compounds.

the answer is c

the answers are

c and c

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
