at 1500 celcius the system 2NO<-->N2+O2 was allowed to come to equilibrium. the equilibrium concentrations were NO=0.00035M N2=0.040M O2=0.040M What is the value of Kc for the system at this temperature? The answer they give is 1.3 x10^4 Im getting 2.2 x1...

Use Euler's method with step size 0.1 to estimate y(0.5), where y(x) is the solution of the initial-value problem y ' = y + 4xy, y(0) = 1. (Round the answer to four decimal places.)

What is the algebraic expression for the following word phrase: the difference between 17m and 3? A. 17m + 3 B. 17m x 3 C. 17m / 3 D. 17m - 3 YA'LL HELP ME I DONT NEED THE ANSWER JUST EXPLAIN IT TO ME PLEASE

THANKS

They give answer 0.0984 mol and i get 3 something

ok iget 0.328 not 0.0984

HX) = 0.600 mol/3.00L = 0.2 M (H2) = 0.150 mol/3.00L = 0.05M (0.2)^2/0.05)(24.4)=0.327

ok i get 24.4/3 = 8.13 and the solve for x2
