Hey there!
Molar mass NaCl = 58.44 g/mol
58.44 g ----------------- 22.4 ( at STP )
3.2 g -------------------- Volume ??
Volume = ( 3.2 x 22.4 ) / 58.44
Volume = 71.68 / 58.44
Volume = 1.226 L
Hope this helps!
<span>Use the Arrhenius equation. Use p1 and p2 and T1 and T2 and solve for Ea (actgivation energy) in Joules, then plug that back into the Arrhenius equation and either p1 or p2 to calculate p at 25C.</span>
Answer:
See explanation
Explanation:
The land around us appears flat because the Earth is just so unimaginably large, and the curvature is extremely small from our point of view. In reality, the land is slightly bendy, which is why certain structures (like very long bridges) need to be constructed with the curvature in mind, with different ends at slightly different elevations. Hope this helps!
66.2% yield
The balanced equation for the reaction is:
2C6H10 + 17O2 ==> 12CO2 + 10H2O
So for every 2 moles of C6H10 consumed, we should get 12 moles of CO2. Or to simplify, for each mole of C6H10, we should get 6 moles of CO2. Now let's calculate the molar mass of C6H10 and CO2 and then determine how many moles of each we really have.
Atomic weight carbon = 12.0107
Atomic weight hydrogen = 1.00794
Atomic weight oxygen = 15.999
Molar mass C6H10 = 6*12.0107 + 10*1.00794 = 82.1436 g/mol
Molar mass CO2 = 12.0107 + 2*15.999 = 44.0087 g/mol
Moles C6H10 = 8.88 g / 82.1436 g/mol = 0.10810337 mol
Moles CO2 = 18.9 g / 44.0087 g/mol = 0.429460538 mol
Since we had 0.10810337 moles of C6H10, we should have gotten
6*0.10810337 = 0.648620221 moles of CO2, but only got 0.429460538 moles. So let's divide the actual yield by the theoretical yield to get the percentage yield.
0.429460538 / 0.648620221 = 0.662114014 = 66.2%
