Answer:
The partial pressure of neon in the vessel was 239 torr.
Explanation:
In all cases involving gas mixtures, the total gas pressure is related to the partial pressures, that is, the pressures of the individual gaseous components of the mixture. Put simply, the partial pressure of a gas is the pressure it exerts on a mixture of gases.
Dalton's law states that the total pressure of a mixture of gases is equal to the sum of the pressures that each gas would exert if it were alone. Then:
PT= P1 + P2 + P3 + P4…+ Pn
where n is the amount of gases present in the mixture.
In this case:
PT=PN₂ + PAr + PHe + PNe
where:
- PT= 987 torr
- PN₂= 44 torr
- PAr= 486 torr
- PHe= 218 torr
- PNe= ?
Replacing:
987 torr= 44 torr + 486 torr + 218 torr + PNe
Solving:
987 torr= 748 torr + PNe
PNe= 987 torr - 748 torr
PNe= 239 torr
<u><em>The partial pressure of neon in the vessel was 239 torr.</em></u>
Answer:
A) Test(independent) variable is bat wings.
B) Result (dependent) Variable is the Polyjuice Potion.
C) Cauldrons and fire
Explanation:
A) A test/independent variable is the variable that is being tested in the experiment or research and it is not affected by other variables in the experiment.
Now, in this experiment, what is being tested is are the bat wings.. Thus;
Test(independent) variable is bat wings.
B) Result (dependent) Variable is a variable that depends on the independent variable being tested. From the question, the result is the Polyjuice Potion.
Thus, Result (dependent) Variable is the Polyjuice Potion.
C) The constants are things that don't change with respect to any of the other variables. In this case, they are; cauldrons and fire
Salad is biotic, it is made from plants and plants are alive.
biotic means alive
abiotic means not alive
