I searched for complete question (as your question is missing with structure) and found the structure of compound attached below.
Answer: The compound can
neither act as a Hydrogen Bond Donor
nor act as a Hydrogen Bond Acceptor.
Explanation: For two compounds to build Hydrogen Bond Interactions it is compulsory that they must contain Hydrogen atoms which are directly attached to most electronegative atoms like
Fluorine,
Oxygen and
Nitrogen.
As the given compound is
2-Butene (a non polar hydrocarbon), it lacks partial positive Hydrogen (which can act as Hydrogen Bond Donor) and a most electronegative element (F, O or N) which can act as Hydrogen Bond Acceptor. Therefore, this compound will not generate any Hydrogen Bonding with water molecules and will remain immiscible in it.
The Equation is CaH2(s)+2H2O(l)-->Ca(OH)2(aq)+2H2(g)
so,
moles of H2 generated = PV / RT
R = 62.363 L Torr K−1 mol−1
number of moles = 814 * 53.5 / 62.363 * 293
= 2.38 moles
looking at the equation these came from 2.38 /2 moles of CaH2 or 1.19 moles
Molar mass of CaH2 is 42.0943 g/mol
so mass of CaH2 = 1.19 X 42.1 = 50.01g
Answer:
<h2>0.93 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 37.2 g
volume = 40 mL
We have

We have the final answer as
<h3>0.93 g/mL</h3>
Hope this helps you
