Answer:
The pressure of the gas would be 3.06 atm
Explanation:
Amonton's law states that the pressure is directly proportional to the absolute temperature of a gas under constant volume. The equation is:
P1 / T1 = P2 / T2
<em>Where P1 is the initial pressure = 3.16atm</em>
<em>T1 is initial absolute temperature = 273.15 + 32.2°C = 305.35K</em>
<em>P2 is our incognite</em>
<em>And T2 is = 273.15 + 22.9°C = 296.05K</em>
<em />
Replacing:
3.16atm / 305.35K = P2 / 296.05K
3.06 atm = P2
<h3>The pressure of the gas would be 3.06 atm</h3>
Answer:
The heat at constant pressure is -3,275.7413 kJ
Explanation:
The combustion equation is 2C₆H₆ (l) + 15O₂ (g) → 12CO₂ (g) + 6H₂O (l)
= (12 - 15)/2 = -3/2
We have;
Where R and T are constant, and ΔU is given we can write the relationship as follows;
Where;
H = The heat at constant pressure
U = The heat at constant volume = -3,272 kJ
= The change in the number of gas molecules per mole
R = The universal gas constant = 8.314 J/(mol·K)
T = The temperature = 300 K
Therefore, we get;
H = -3,272 kJ + (-3/2) mol ×8.314 J/(mol·K) ×300 K) × 1 kJ/(1000 J) = -3,275.7413 kJ
The heat at constant pressure, H = -3,275.7413 kJ.

Answer:
Chlorine is a very reactive non metals because this element don't form any known chemical compound.
Explanation:
Chlorine atoms have a lot of valance electrons without being complete on its own, so it has a greater need to seek it's conjugates. That's called electronegativity. Halogens are highly reactive because of their electronegativity.
