Answer:
125.681 torr
Explanation:
The formula to calculate the partial pressure of oxygen:
P(O2) = Pcommon - PCO2 - PN2
1 atm = 760 torr
Therefore you need to find the partial pressure of oxygen:
P(O2) = 760 torr -0.285 torr - 634.034 torr =130.013 torr

Answer: as copper has lower electrode potential value than hydrogen, it could be reduced by hydrogen.
Explanation: hydrogen has zero reduction potential while Cu has +0.34V and Al has -1.66 V .
SO in electrochemical series who has most negative or less reduction potential value tends to be a good reducing agent than the other.

Because alcohol expands over small temp changes, hence while a vial of it is used in sprinklers as the stop plug; the room gets hotter, the plug shatters.
Answer:
For finding frequency, we need to first find the period of the graph.
The period of a sinusoidal graph is the time interval in which it repeats its pattern.
In the graph, we can see, after 
time, it repeats its pattern.
Hence the period of the graph is 
.
Now we need to find its frequency 
The formula for frequency is 
This is the answer
