Answer:

Oxidation occurs when a reactant loses electrons during the reaction. Reduction occurs when a reactant gains electrons during the reaction. This often occurs when metals are reacted with acid.

Answer : Oxidation reaction occurs when a reactant losses electrons in the reaction.

Reduction reaction occurs when a reactant gains electrons in the reaction.

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.

Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.

Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.

Which statement is correct about the location of electrons in an atom according to the Quantum mechanical model? A) Electrons ar
katrin2010 [14]

Answer:

B) Electrons are located in the cloud-like areas around the nucleus.

Explanation:

The quantum mechanical model of the atom does not consider the path through which an electron travels. It rather estimates the probability of where electrons can be found at each energy level.

The region of maximum probability of where an electron is located is sometimes called an electron cloud or orbital. Each orbital of an atom and the electrons accomodated are described completely by a set of four quantum numbers.

Is H3O+ polar or non polar? (explain please.)?
pishuonlain [190]
The overall molecule is Polar because the shape of the molecule is Trigonal Pyramidal, which means it has the lone pair electrons. Becuase of the lone pair the pulling is unequal.   

H3O+ has 3 polar bonds. 
To know if the bonds are polar or nonpolar find the difference of the element's electronegativity charge. 
H has electronegativity charge of 2.2, and O has 3.4.
Always subtract the smaller number from the greater one. 
So 3.4 - 2.2 = 1.2 
If the difference is from 0-0.4 the bond is nonpolar, but if it's from 0.5-1.9 the bond is polar. 
So, 1.2 is polar bond. So H3O+ has 3 polar bonds, and the overall molecule is polar too. 

A simple way to know if it's polar or nonpolar is to draw the lewis dot structure, and use VSEPR.
