mr Goodwill [35]

Answer:

The equillibrium constant Kc = 11.2233

Explanation:

Step 1:

aA + bB ⇔ cC + dD

with a, b, c and d = coefficients

Kc = equillibrium constant =( [C]^c [D]^d ) / ( [A]^a [B]^b)

Concentration at time t

[A] = 0.300 M

[B] =1.10 M

[C] = 0.450 M

Change :

A: -x

B: -2x

C: -x

The following reaction occurs and equillibrium is established

A + 2B ⇔ C

[A] = 0.110M

[B] = ?

[C] = 0.640 M

For A we see that after change: 0.3 -x = 0.11

Then for B we have 1.1 - 2x = ? ⇒ 1.1 -2 *0.19 = 0.72

This gives us for the equillibrium constant Kc = [C] / [A][B] ²

Kc = 0.64 / (0.11) * (0.72)² = 11.2233

amid [387]

Answer:

3°F, 0°F, -11°F, -16°F, -20°F

Explanation:

The Fahrenheit scale is a temperature scale proposed in 1724 by the physicist Daniel Fahrenheit.

In this scale:

- The freezing point of water is set at 32 degrees

- The boiling point of water is set at 212 degrees

One degree in the Fahrenheit scale is indicated with the symbol $^{\circ}F$ .

The equivalence between temperature in Celsius degrees and Fahrenheit degrees is as follows:

$T(^{\circ}C)=\frac{5}{9}(T(^{\circ}F)-32)$ to convert from Fahrenheit to Celsius

$T(^{\circ}F)=\frac{9}{5}(T(^{\circ}C)+32)$ to convert from Celsius to Fahrenheit

The Fahrenheit scale is an increasing monotonic scale, it means that temperature goes from negative values towards positive values without interruption. Therefore, the temperatures listed from warmest to coldest are:

3°F, 0°F, -11°F, -16°F, -20°F
