Answer:
the most common is 'direct combustion'.
Answer:
C
Explanation:
Well, we can see from the equation that hydrogen gas and ethane are in a 2:1 ratio based on their mole coefficients.
You need 2 mol H2 to make 1 mol C2H6. So that means you need 2*13.78 mol H2 to make 13.78 mol C2H6!
2*13.78 = 27.56 mol
C is correct.
For a hydrogen atom, composed of an orbiting electron bound to a nucleus of one proton, an ionization energy of 2.18 × 10−18 joule (13.6 electron volts) is required to force the electron from its lowest energy level entirely out of the atom.
Answer:
NaOH = 40 g/mole
M = 10*d*m% /MW
M = 10*1.116*15/ 40
M = 4.185
––––––––––––––––––––
pH = 11 –––> pOH = 3 –––> [OH–] = 10^–3 M
M1*V1 = M2*V2
4.185* V1 = 10^–3 * 5.3
V1 = 1.27×10^–3 L = 1.27 ml
