Answer:
A !!
it a mix where everything is combined together
From Grahams Law the rates of effusion of two gases are inversely proportional to the square roots of their molar masses at the same temperature and pressure.
Therefore; R1/R2 = √mm2/√mm1
The molecular mass of Carbon dioxide is 44 g
Hence; 1.8 = √(44/x
3.24 = 44/x
x = 44/3.24
= 13.58
Therefore, the molar mass of the other gas is 13.58 g/mol
Answer:
Explanation:
Scientists don't stop with the first step of their experiment because they want other scientists' opinions because they may not trust their own observations.
OR
Scientists don't stop with the first step of their experiment because they would rather plan and run experiments than just observe the world around them
Hope any one of these helps you
Answer: I believe it’s element symbols
Explanation: I hope we both get it right
Answer:
Explanation:
Hello!
In this case, since this a problem in which the cold water is heated by the hot water, we can write:
Thus, by plugging in the mass, specific heat and temperatures, we obtain:
Now, we can also write:
Then, after applying some algebra, it is possible to obtain:
If we plug in, we obtain:
Best regards!
