<u>Explanation:</u>

Valence electrons are defined as the electrons which are present in the outermost shell of an atom.

The number of valence electrons in a particular group will be equal to the group number.

Number of valence electrons = Group number

The given table follows:

Group       Most likely ionic charge      No. of valence electrons

   I                                  +1                                            1

  II                                 +2                                            2

 III                                 +3                                            3

 IV                             +4 or -4                                       4

  V                                -3                                              5

 VI                                -2                                              6

 VII                                -1                                              7

VIII                                 0                                             8

Answer: In order to increase the rate of reaction between hydrochloric acid and sugar increase the concentration of hydrochloric acid to 2 M because greater concentration results in more collision between the reactants.

Explanation:

More is the concentration of reactant molecules more will be the number of collisions between their molecules. As a result, more readily the products will be formed.

Hence, for the given reaction when concentration of HCl is increased then there will be increase in the number of collisions between reactants.

Thus, we can conclude that in order to increase the rate of reaction between hydrochloric acid and sugar increase the concentration of hydrochloric acid to 2 M because greater concentration results in more collision between the reactants.

What is the molarity of an H3PO4solution if 15.0 mL is completely neutralized by 38.5 mL of 0.150 MNaOH? Please explain your ans
rodikova [14]

Answer:

M=Molarity

V=volume

change millilitre to litre

so:15ml=0.015 L

:38.5ml=0.0385 L

M1V1=M1V1

M1* 0.015 L= 0.15M*0.0385 L

M1=0.00385
