Answer:
Theoretical 32.04 g
The precent yeild 87. 39 %
Explanation:
Mole of H2 = m/mw = 4/2 = 2 mol
From the equation
1 mol H2 --> 1/2 mol CH3OH
2 mol H2 -->??
So we have 1 mol Ch3oh
Mass of Ch3oh = mole *Mw = 1* 32.04
= 32.04g >>> the theoretically
For percent yeild = actual / theoretical * 100%
( 28.0/32.04) *100% =
87.93%
The solution is a weak base. a weak base is that which dissociates partially in aqueous solution to give hydroxide ions as the only negatively charged ions. In the provided information, only 32 %of the substance dissociates thus it is a partial dissociation. Most of the energy is used to break bonds thus the remaining energy is not enough to cause complete dissociation.
