Write an equation that gives the overall equilibrium constant in terms of the equilibrium constants and . If you need to include

shutvik [7]

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\\\\$

AB=6CM AC= 12cm <br> calculate the length of CD

Brrunno [24]

AB=6cm AC=12cm

AC² = AB + BC²

12² = 6² + CB²

CB² = 12² - 6²

CB² = 144 - 36

CB² = 108

CB = √ 108 cm.

sin 55° = CB / CD

0.81915 = √108 / CD

CD = 10.392 / 0.81915

CD = 12.686 cm

Find the volume of the composite figure. Give your answer in terms of pi.

Sloan [31]

Volume of cone= 1/3 πr²*h
15²=10²+h²
h²=15²-10²=125
h=√125
Volume of cone= 1/3 *π*100*√125=π/3*(100*5√5)=500π√5/3
Volume of sphere=4/3*π*r³=4/3*π*1000=4000π/3
Volume of half sphere=(4000π/3)/2=2000π/3
All Volume=500π√5/3+2000π/3

Alexus [3.1K]

81ft(yd/3ft)*111ft(yd/3ft)*2in(yd/36in)=55.5 yd^3

So 55 1/2 cubic yards of topsoil are needed.
