<h3>
Answer:</h3>
112.08 mL
<h3>
Explanation:</h3>
From the question we are given;
- Initial volume, V1 = 100.0 mL
- Initial temperature, T1 = 225°C, but K = °C + 273.15
thus, T1 = 498.15 K
- Initial pressure, P1 = 1.80 atm
- Final temperature , T2 = -25°C
= 248.15 K
- Final pressure, P2 = 0.80 atm
We are required to calculate the new volume of the gases;
- According to the combined gas law equation;
Rearranging the formula;
Therefore;
Therefore, the new volume of the gas is 112.08 mL
~Hello there! ^_^
Your question: Why should we not throw water in petrol fire..?
Your answer: We should not throw water in the petrol fire because oil, petrol etc are a bit weightless than water so it continues to flow over the water.
Hope this helps!
When salt dissolves in water, the water molecules are attracted by dissolves salt particles. This attraction is called dissociation.
Hope this helps you. Do mark me as brainliest.
According to the reaction equation:
by using ICE table:
CO(g) + Cl2(g) ↔ COCl2(g)
initial 0.025 0.0035 0
change -X -X +X
Equ (0.025-X) (0.0035-X) X
when:
Kp = P(COCl2)/P(CO}*P(Cl2) when Kp= 0.2
by substitution:
0.2 = X / (0.025-X)(0.0035-X) by solving this equation for X
∴ X = 1.74x10^-5
