Answer: It is true for the process used to achieve the required dilution that volume of the solvent used is less than 2 liters.

Explanation:

Given: M_{1} = 10 M,       V_{1} = ?

M_{2} = 1 M,       V_{2} = 2 L

The volume of stock solution is calculated as follows.

M_{1}V_{1} = M_{2}V_{2}\\10 M \times V_{1} = 1 M \times 2\\V_{1} = 0.2 L

A solution which contains small amount of solute is called a dilute solution. Whereas a solution which contains more amount of solute is called a concentrated solution.

The stock solution is used for dilution and hence, it acts as a solvent. Its calculated volume is 0.2 L.

This means that volume of the solvent used is less than 2 liters.

Thus, we can conclude that it is true for the process used to achieve the required dilution that volume of the solvent used is less than 2 liters.

What is the correct balanced equation for the reaction of sodium with water?
Wittaler [7]

Answer:

 A.    2Na       +    2H₂O   →    2NaOH   +  H₂  

Explanation:

When sodium is reacted with water, a single replacement reaction occurs. The product of the reaction is typically sodium hydroxide and hydrogen gas.

Reactants:

        Sodium +  water

Product:

        Sodium hydroxide + hydrogen gas

So;

         2Na       +    2H₂O   →    2NaOH   +  H₂

Identify the blocks and groups of elements in the periodic table​
djyliett [7]

Explanation:

The periodic table is a table that arranges elements based on their atomic numbers into groups and periods.

The groups are the vertical arrangement of elements. All elements in a group share similar chemical properties because they have the same number of elements in their valence shell. The periodic table groups are:

               Group                             Other names

              1A or 1                               Alkali metals

              IIA or 2                              Alkaline earth metals

             IIIA or 3                            Boron family

             VIA or 6                             Chalcogens

            VIIA or 17                            Halogens

             O-18                                  Inert elements

             IIIB-IIB                              Transition elements

There are 18 vertical columns divided into 8 tall groups or main groups which are 1A to O. The short groups or subgroups are from numerals 1B to VIII.

The periodic table can be divided into four blocks based on the type of sublevels their valence electrons occupy.

  • Group IA and IIA constitute the s-block
  • Group IIIA to O constitute the p-block
  • The transition elements makes up the d-block
  • The lanthanides and actinides makes up the f-block
