Chlorine dioxide is used as a disinfectant and bleaching agent. In water, it reacts to form chloric acid (HClO3),

Be sure to answer all parts. the equilibrium constant (kp) for the reaction below is 4.40 at 2000. k. h2(g) + co2(g) ⇌ h2o(g) +

svetoff [14.1K]

When we have the balanced reaction equation is:

H2(g) + CO2(g) ↔ H2O(g) + CO (g)

a) first, to calculate ΔG° for the reaction:

we will use this formula:

ΔG° = -RT㏑Kp

when R is R- rydberg constant = 8.314J/mol.K

and T is the temperature in Kelvin = 2000 K

and Kp = 4.4

so, by substitution:

ΔG° = - 8.314 *2000 *㏑4.4

= - 24624 J/mol = - 24.6 KJ/mol

b) to calculate ΔG so, we will use this formula:

ΔG = ΔG° + RT㏑Qp

So we need first, to get Qp from the reaction equation:

when Qp = P products / P reactants

= PH2O*PCO / PH2 * PCO2

= (0.66 atm * 1.2 atm) / (0.25 * 0.78)

= 4.1

so by substitution:

ΔG = -24624 + 8.314*2000*㏑4.1

= -1162 J/mol = - 1.16 KJ/mol

The line graph shows the heights of plants grown in fertilized and unfertilized soil. Based on this information, what will most

Helen [10]

Answer:

g) Neither plant should increase by 1 cm in height.

Explanation:

See the graph for this question on the figure attached.

The growing of the plant A is represented by the line that goes above the other. At start, that line has a slope that rises about 0.75 cm ( height increase) in 1 day. From the day 2 and forward the slope of the line decreases. The line reaches its highest point about at day 4 and seems to start decreasing. Thus, you should predict that on the day six it most likely does not increase in height.

The growing of the plant B is represented by the line drawn below the other. As for the plant B, the growing decreases with the number of days. Between the days 4 and 5 the line is almost flat, which means that most likely this plant will not grow on the day six or grow less than 0.5 cm.

Thus, for both plants you can say that on day six, most likley, neither should increase by 1 cm in height (option g).

Reaching 29,029 feet (8,848 meters) above sea level, Mount Everest is the highest mountain on Earth. Located in the Mahalangur section of the Himalayas, the mountain's summit straddles the border separating China and Nepal.

Or if you want a more literary description, try some devices to describe it i.e what's there, the atmosphere, the height/gradient etc.
