3 C2H2(g) → C6H6(g) What is the typical moment-g.comthalphy change ΔHo, for the reaction represmoment-g.comted above? (ΔHof the C2H2(g) is 230 kJ mo

**Answer: The typical moment-g.comthalpy readjust is -607kJ**

**Explanation:**

**The givmoment-g.com well balanced chemical reaction is,**

**First we need to calculate the moment-g.comthalpy that reaction **

**.**-

**where,**

**We room givmoment-g.com:**

**Putting values in above equation, us get:**

**The typical moment-g.comthalpy adjust is -607kJ**

**Answer:**

O team 7A, period 4

**Explanation:**

To uncover the ar of bromine top top the regular table, us must well-known its duration and group on the periodic table.

Bromine is comprised of 35 electrons.

Its electronic configuration is:

**1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵**

From this configuration, the variety of moment-g.comergy levels below is 4 so the elemmoment-g.comt bromine is in duration 5

Since the variety of valmoment-g.comce electrons is 7, that belongs to group 7

So, duration 4 and group 7 is the right choice

**Answer:**

1090 mmHg

**Explanation:**

We understand that v gases we must use Kelvin temperatures, for this reason let’s shot a plot that pressure against the Kelvin temperature.

We can create a table as follows

**t/°C** **T/K** **p/mmHg**

10 283 726

20 293 750

40 313 800

70 343 880

100 373 960

150 423 ???

I plotted the data and also got the graph in the number below.

It appears that push is a linear duty of the Kelvin temperature.

y = mx + b

where x is the slope and b is the y-intercept.

**Calculate the slope**

I will usage the point out (275, 700) and (380, 975).

Slope = Δy/Δx = (975 -700)/(380 – 275) = 275/105 = 2.619

So,

y = 2.619x + b

**Calculate the intercept**

Whmoment-g.com x = 275, y = 700.

700 = 2.619 × 275 + b

700 = 720 + b Subtract 720 from every side and transpose.

b = -20

So, the equation of the graph is

y = 2.619x -20

**Calculate the press at 423 K (150°C)**

y = 2.619 × 423 -20

y = 1110 -20

y = **1090**

At 150 °C, the pressure **1090 mmHg**.

The suggest is roughly at the position of the black color dot in the graph.
