Answer:
where are the answer choices
Explanation:
Answer:
C
Explanation:
Charles law states that volume of gas is directly proportional to temperature at constant pressure
V/T = k
where V - volume , T - temperature and k - constant
\frac{V1}{T1} = \frac{V2}{T2}
T1
V1
=
T2
V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
in the question it states that the temperature has been increased from 278 K to 231 K but it should actually be temperature is decreased from 278 K to 308 K
substituting the values in the equation
\frac{417cm^{3} }{278K} = \frac{V}{308 K}
278K
417cm
3
=
308K
V
V = 462 cm³
the answer should be C. 462 cm³
Answer: 7.41 L of O2
Explanation:
2H2O2(l) ----> 2H2O(l) + O2(g)
22.5 g H2O2 x __1 mol__ x __1 mol O2__ x __22.4 L__ = 7.41 L of O2
34.016 g 2 mol H2O2 1 mol O2
Answer:
Not sure what the specific answer you want is but here's mine..
Earth science or geoscience includes all fields of natural science related to the planet Earth. SO.. They would study how the world works. AN example is natural disasters.

Explanation:
Hello,
At first, it turns out convenient to compute the total moles of sodium that will be dissolved into the solution by considering the added amounts of sodium bromide and sodium sulfate:
Once we've got the moles we compute the final volume via:
Thus, the molarity of the sodium atoms turn out into:
Now, we perform the same procedure but now for the bromide ions:
Finally, its molarity results:
Best regards.
