Answer:

The answer is "k=k_1k_{2}^2"

Step-by-step explanation:

For point 1:

4NHH_3 \ (g) +5O_2\ (g)  \leftrightharpoons  4NO\ (g) +6H_2O \ (g)..................k_1\\\\

For point 2:

2 \times(2\ NO\ (o)+O_2 \ (g)  \leftrightharpoons  2NO_2\ (g)) ..................K_2\\\\

Adding k_1 equation and  multiply by 2 in the equation k_2 so we get  \to 4NH_3\ (g) +7 O_2\ (g) \leftrightharpoons 4 NO_2\(g) +6H_2O\ (g)....... k\\\\k= k_1\times k_{2}^2\\\\k=k_1k_{2}^2\\\\

What is the correct evaluation of 4x2 + 4x - 2y2 +3y, when x is equal to -2 and y is equal to 3?
____ [38]

Answer:

-1

Step-by-step explanation:

This all comes down to the substitution. I am assuming that (4x2) is meant to be 4x^2 so I will solve as that.

4(-2)^2 = 4(4) = 16

4(-2) = - 8    

-2(3)^2 = -2(9) = -18

3(3) = 9

16-8-18+9= -1
