A mixture of oxygen, hydrogen, and nitrogen exerts a total pressure of 378 kPa. If the partial pressures of oxygen and hydrogen
sertanlavr [38]
What's the relationship between total and partial pressure? The total pressure is the sum of the parcial pressures!


So for us, it would be:

378= 212+101+x

where x is the parcial pressure of nitrogen.

Now we count:
378= 212+101+x
378=313+x
378-313=x
65=x

So the parcial pressure exerted by nitrogen is 65!

a stock solution has a concentration of 0.30 m clo2 and is diluted to become a 0.20 m solution with a volume of 0.050 l. what wa
Pavlova-9 [17]

The stock solution has a volume of 0.208L. When diluted, a stock solution with a concentration of 0.30 m clo2 becomes a 0.20 m stock solution with a volume of 0.050.

A three-dimensional space's occupied volume is measured. It is frequently measured numerically with SI-derived units (such the cubic metre and litre) or with other imperial units (such as the gallon, quart, cubic inch). Volume and length are related in how they are defined (cubed).

A highly concentrated stock solution, often prepared as a 10x concentrated solution, can be described as a stock solution since it can be diluted to create a working solution. In order to prepare complex solutions with numerous constituents, stock solutions can also be utilized as a component.

0.3M*v = 0.125M*0.50L

V=0.208L

Which three temperature readings all mean the same thing?
Viktor [21]

Answer:

C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

Explanation:

Kelvin and Celsius are related using the equation K = C + 273.

Celsius and Fahrenheit are related using the equation F = (9/5) * C + 32.

This means that Kelvin and Celsius have to differ by 273, in which only B and C fit that description.

Then you can look at the Celsius and Fahrenheit readings from B and C and apply the equation F = (9/5) * C + 32. For B, you take 0 degrees Celsius and substitute it in for C to get F = (9/5) * 0 + 32, in which you get 32 degrees Fahrenheit and <em>not </em>the 212 degrees in answer B. For C, you do the same: F = (9/5) * 100 degrees Celsius + 32 = 212 degrees Fahrenheit, which does agree with the answer. Therefore, it must only be C.
