Answer:
The pressure is 
Explanation:
From the question we are told that
The volume of Ne is 
The volume of CO is 
The pressure of 
is 
The pressure of CO is 
The number of moles of Ne present is evaluated using the ideal gas equation as
=> 
The number of moles of CO present is evaluated using the ideal gas equation as
=> 
The total number of moles of gas present is evaluated as
The total volume of gas present when valve is opened is mathematically represented as
=> 
So
From the ideal gas equation the final pressure inside the system is mathematically represented as
=> ![P_f = \frac{[\frac{4.185}{RT} ] * RT }{ 4.50}](https://tex.z-dn.net/?f=P_f%20%20%3D%20%20%5Cfrac%7B%5B%5Cfrac%7B4.185%7D%7BRT%7D%20%5D%20%20%2A%20%20RT%20%7D%7B%204.50%7D)
=>
Copper<span>(II) </span>oxide<span> or cupric </span>oxide<span> is the inorganic </span>compound<span> with the formula CuO. A black solid, it is one of the two stable </span>oxides<span> of </span>copper, the other being Cu2<span>O or cuprous </span>oxide<span>. As a mineral, it is known as tenorite and paramelaconite.</span>
Answer:
The elements in group 13 and group 15 form a cation with a -3 charge each.
To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration
of the stock solution, V1 is the volume of the stock solution, M2 is the
concentration of the new solution and V2 is its volume.
M1V1 = M2V2
1% x V1 = 0.25% x 10 mL
V1 =2.5 mL
Therefore, you will need to have 2.5 mL of the 1% HCl solution and 7.5 mL of distilled water. In mixing the two liquids, you should remember that the order of mixing would be acid to water. So, you use a 10 mL volumetric flask . Put small amount of distilled water and add the 2.5 mL of HCl solution. Lastly, dilute with distilled water up to the 10 mL mark.
