Answer: maybe mixing with an acid? They are all very similar
Explanation:
Maybe because the different acids have different atoms and molecules
Answer:
One mole of anything has 6.023 x 10^23 molecules.
That would mean 3.4moles of CO2 have 6.023x 10^23 times 3.0.
So that would be2.04782×10^24 molecules in 3.0 moles of C02.
<span>Technically, this question is badly worded. If all 4 containers were at STP, then all 4 containers would have the same pressure. So I'll assume instead that all 4 containers are at the same temperature, and then use the ideal gas law to determine the relative internal pressures of each container.
The idea gas law is
PV = nRT
where
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant
T = Absolute temperature
Since all the containers are at the same temperature, we can ignore the R and T parts of the formula and substitute some value K for constant. So we get
PV = nK
Now solve for P
PV = nK
P = nK/V
From the above, you can see that the pressure is proportional to the number of moles divided by the volume. So let's calculate that value for each container.
Container A: 0.5 / 11.2 = 0.044642857
Container B: 2 / 22.4 = 0.089285714
Container C: 1 / 22.4 = 0.044642857
Container D: 2 / 11.2 = 0.178571429
So as you can see, the pressures in containers A and C are the same, which is the first available option, so you are correct.</span>
Answer:
No
Explanation:
The Earth would not have seasons if there is no revolution because the temperatures would not change.
