Are the statements about hydrogen bonding of the compound below with water true or false? this compound can act as a hydrogen-bo
nd donor. this compound can act as a hydrogen-bond acceptor
2 answers:
Here we have to judge the statement about the hydrogen bond is true or false for water molecule.
The both the statement about hydrogen bonding in water is true i.e. The water molecule can act as hydrogen-bond donor and acceptor.
The hydrogen bond is a weak interaction between a hydrogen atom and an electronegative atom.
In water (H₂O) there remains hydrogen atom (H) and also the electronegative atom oxygen (O). The donor property and acceptor property to produce hydrogen bond in water is shown in figure.
The donor and acceptor property of water is shown in the figure.

Answer:
number of moles of the compound 53 mole
Explanation:
Given that:
The total energy liberated = - 2870 kJ ( here , the negative sign typical implies the release of energy due to the combustion reaction)
The equation of the reaction can be represented as:
The energy needed to synthesize 1 mole of compound X = - 54.1 kJ.mol
Thus;
The total energy = numbers of moles of compound × Energy needed to synthesize 1 mole of compound X
Making the numbers of moles of the compound the subject; we have;
numbers of moles of compound =
number of moles of the compound = 53.04990 mole
number of moles of the compound 53 mole to two significant figure
Explanation:
Oxidation reduction reactions are the reactions in which one specie oxidizes and other reduces.
For example,
This is a oxidation reduction reaction because sodium in elemental state ( 0 oxidation state) oxidizes to Na⁺ in NaCl. Also H⁺ in HCl reduces to H° in H₂.
Elements are present in 0 oxidation state and either it is formed or consumed, its oxidation state has to be changed for a chemical reaction to occur. Hence, it is true.
