<h2>Answer:</h2><h3>Balanced equation:</h3>
2C4H10 + 8O2 → 8CO2 + 10H2O
<h3>Description:</h3>
There should be 8 molecules of oxygen which react with 2 molecules of butane to produce 8 molecules of carbon dioxide and 10 molecules of water.
Answer:
B = - 0.0326 dm³/mol
Explanation:
virial eq until second term:
∴ P = 10 bar * (atm/ 1.01325 bar) = 9.869 atm
∴ T = 200°C = 473 K
∴ Vm = 3.90 dm³/mol
∴ R = 0.08206 dm³.atm/K.mol
⇒ PVm / RT = 1 + B/Vm
⇒ ((9.869 atm)*(3.90 dm³/mol)) / ((0.08206 dm³.atm/mol.K)*(473K)) = 1 + B/Vm
⇒ 0.99164 = 1 + B/Vm
⇒ B/Vm = - 8.357 E-3
⇒ B = (3.90 dm³/mol)*( - 8.357 E-3 )
⇒ B = - 0.0326 dm³/mol
Answer:
5.65 is the pH.
Explanation:
I am assuming that you are asking for confirmation on your answer. The answer is 5.65.
You would do:
[pOH] = -log[OH-]
= -log[4.5*10^-9]
equals about 8.3468
To find pH your would subtract the pOH from 14.
14-8.3468 = 5.65 << Rounded to match the answer choices.
C2H2 is the right answer I believe
Non polar covalent bond. The Cl's electronegativity is the same since it's the same atom. Therefore, they will be nonpolar
