Answer:
5 will come in blank
4KMnO₄ ----------> 2K₂O + 4MnO + 5O₂
Explanation:
Reaction:
4KMnO₄ ----------> 2K₂O + 4MnO + ____O₂
this reaction is the dissociation reaction in which KMnO₄ is break down into its component.
KMnO₄ upon dissociation gives Potassium oxide, manganese oxide and liberate oxygen
Balance Chemical Equation:
A balanced chemical equation is that in which the the number of the reactant atoms equal to the number of the product atom.
For example if the oxygen at the reactant side is 4, the number of oxygen should be 4 on the product side.
So for this purpose we have to balnce the reaction and number of atoms on each side of the arrow
if we see the given Equation
Numbers of atom on reactant Side:
K = 4
Mn = 4
O = 16
Numbers of atom on reactant Side:
K = 4
Mn = 4
O = 6 instead of blank oxygen molecule
so from the above data we have 10 oxygen less.
If we put the 5 in the blank then we will have 10 oxygen and equation will be balanced
So the balanced Equation will be
4KMnO₄ ----------> 2K₂O + 4MnO + 5O₂
<span>Air enters through the nose or mouth (which join to form the nasopharyngeal cavity). The air travels through the trachea which and the trachea splits into two bronchi. The air travels through the bronchi which split into smaller and smaller bronchioles. The tiny bronchioles and the air ends up in the miniscule alveoli, where the oxygen in the air diffuse into the bloodstream. Carbon dioxide diffuse from the bloodstream into the alveoli and the unwanted gas travels in reverse back to the nose and mouth, where it is breathed out.</span>
Answer:The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound, C5H10O2, exhibits strong, broad absorption across the 2500-3200 cm^1 region and an intense absorption at 1715 cm'^-1. Relative absorption intensity: (s)=strong, (m)-medium, (w) weak. What functional class(cs) docs the compound belong to List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 cm^1. The functional class(es) of thla compound is(are) alkane (List only if no other functional class applies.) alkene terminal alkyne internal alkyne arene alcohol ether amine aldehyde or ketone carboxylic acid ester nitr
Answer:
Hydrogen bonding is caused by the tendency of some atoms in molecules to attract electrons more than their accompanying atom. This gives the molecule a permanent dipole moment , it makes it polar, so it acts like a magnet and attracts the opposite end of other polar molecules.
