It's -Bohr's Model- becuase Dalton I dont think did a model. Thomson's was the "Plum Pudding Model." Ernest Rutherford drew one out(I dont know i dont have a model down though) so it the only one left is Dalton's Model which is it. (Hopefuly)
Hypothesis is your opinion/ your thinking and yes, scientists have hypothesis before they do an experiment
Hope this helps!
<span>If the the level of water in a container is compared before and after the fusion, it can be realized that the ice has a higher level than that of liquid water: solid and liquid water does not have the same volume.
</span><span>We can generalize:
A state change always causes a change in volume.
Comment:
Water is an exception, volume increases during a melting for most of substances.</span>
Answer:
Sea ice
Explanation:
Sea ice has a much higher albedo compared to other Earth surfaces
Use the Ideal Gas Law to find the moles of gas first.
Be sure to convert T from Celsius to Kelvin by adding 273.
Also I prefer to deal with pressure in atm rather than mmHg, so divide the pressure by 760 to get it in atm.
PV = nRT —> n = PV/RT
P = 547 mmHg = 547/760 atm = 0.720 atm
V = 1.90 L
T = 33°C = 33 + 273 K = 306 K
R = 0.08206 L atm / mol K
n = (0.720 atm)(1.90 L) / (0.08206 L atm / mol K)(306 K) = 0.0545 mol of gas
Now divide grams by mol to get the molecular weight.
3.42 g / 0.0545 mol = 62.8 g/mol
