Answer:
76 mmHg
Explanation:
The partial pressure of a gas in an ideal gas mixture is the pressure that this gas would exercise if it was alone in the same temperature of the gas mixture.
For the Raoult's law, we can determinate the partial pressure of a gas(Pa) knowing the total pressure (P) and its molar fraction(Xa):
Pa = XaP, so for the oxygen :
Pa = 0.10x760
Pa = 76 mmHg
Answer:
the heat exchange between the system and the surrounding medium
Explanation:
The first law of thermodynamics states that: "Energy can neither be created nor destroyed, but can convert from one form to another"
It is represented mathematically as:
<span>Δ e=q-w
where:</span>
<span>Δ e is the total change in the system's internal energy
q is </span><span>the heat exchange between the system and the surrounding medium
w is the work done either on the system or by the system
Hope this helps :)

C is the answer.. B and D don't have anything to do with speed
Answer:
The formation of ice can also break rocks. If water gets into a crack in a rock and then freezes, it expands and pushes the crack further apart. When the ice melts later, water can get further into the crack. When the water freezes, it expands and makes the crack even bigger.

Answer:
Ferric chloride test
Explanation:
The ferric chloride test can be used to detect metabolites in urine in case of inborn error of metabolism such as phenylketonuria. Compounds such as phenylpyruvate increase in plasma and are excreted out via urine. Also, it can be used to detect salicylates in urine, quick diagnostic test for aspirin overdose.
