Answer:
the partial pressure of Xe is 452.4 mmHg
Explanation:
Dalton's law of partial pressures says that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.
The partial pressures can be calculated with the molar fraction of the gas, in this case, Xe.
Molar fraction of Xe is calculated as follows:
Then, 0.29 is the molar fraction of Xe in the mixture of gases given.
To know the parcial pressure of Xe, we have to multiply the molar fraction by the total pressure:
Partial Pressure of Xe=1560mmHg*0.29
Partial Pressure of Xe=452.4mmHg
You can find the ratio that it can expand with the atmospheric pressure.
200.0/101.3= 1.97 ≈ 2, this means that the balloon could expand twice its initial volume. So, it is not possible for the balloon to expand to 4 since the maximum is 2.
It’s how low an acid is on the ph balance scale, the strength of an acid depends on how easily the acid gives off hydrogen ions. The scale for acids is 0-6.99 so if the acid is below 5 it’s strong.
Their molecules are constantly in motion, which is why they spread according to the shape of the container and don't have a shape of its own.
When silver ionizes, it donates one electron. A neutral Ag atom has 47 electrons. When it ionizes, it becomes 46. The electronic configuration becomes: [Kr]5s¹4d⁹. Thus, the quantum numbers are:
<em>n = 1,2,3,4,5</em>
<em>l = 0,1,2,3,4 || (0 to n-1)</em>
<em>ml = -4,-3,-2,-1,0,1,2,3,4 || (-l to +l)</em>
<em>ms = +1, -1 </em>
