Resource planning is a technique or skill of proper utilisation of resources. As the resources are limited and unevenly distributed over the country their planning is essential. Resource planning comprises three stages:
(i) Preparation of inventory of resources.
(ii) Evaluation in terms of availability for development.
(iii) Planning for exploitation of resources
• The first stage includes surveying, mapping and measurement of characteristics and properties of resources.
• The second stage examines resources from the points of view of technology, economy and need.
• The third stage is related to action-oriented planning which emphasises use and reuse of the sources.

During the 19th century life was transformed by the Industrial Revolution. At first, it caused many problems but in the late 19th century life became more comfortable for ordinary people. Meanwhile, Britain became the world's first urban society. By 1851 more than half the population lived in towns.

Most of metals react with dilute acids to form salts and hydrogen gas (H2). Reaction of nitric acid with silver Ag + 2HNO3=AgNO3+NO2+H2O Reaction of nitric acid with sodium 2Na + 2HNO3=2NaNO3+H2 Reaction of nitric acid with magnesium Mg + 2HNO3=Mg(NO3)2+H2 Reaction of nitric acid with lead Pb + 2HNO3 =Pb(NO3)2 + H2 Reaction of nitric acid with potassium 2K + 2HNO3 = 2KNO3+ H2 Note = All metals do not liberate hydrogen gas during reaction with dilute because of their low reactivity power but they react with concentrated acids and form entirely different products. Ex - Copper (Cu) ,Silver (Ag) ,Gold (Au) etc...

Steps Involved in Balancing a Chemical Equation:

Consider  the  chemical  reaction  between  magnesium  and  oxygen  to  understand  the  steps  involved  in balancing a chemical equation.

Step 1:

Let us first write the word equation for this reaction.

Magnesium + Oxygen → Magnesium oxide

 

Step 2:

Write the chemical equation for the reaction between magnesium and oxygen.

Mg + O2 → MgO

Step 3:

Count the number of atoms of an element occurring on both L.H.S. and R.H.S. in this equation.

Mg + O2 → MgO

Component

Reactant

Product

Magnesium

1

1

Oxygen

2

1

 

This is an unbalanced equation.

 

Step 4:

To balance a chemical equation, first draw boxes around each formula. Do not change anything inside the boxes while balancing the equation. 

Choose  a  reactant  or  a  product which has  the  maximum  number  of  atoms  in  it. 

In that compound, select the element which has the maximum number of atoms. In this equation we shall select MgO i.e. magnesium oxide and the element oxygen in it.

To balance the oxygen atoms, let us multiply magnesium oxide molecule by 2 on the right hand side.

 

Component

Reactant

Product

Magnesium

1

1 x 2 = 2

Oxygen

2

1 x 2 = 2

 

Step 5:

There  are  two  oxygen  atoms  on  either  side  of  the  equation  but  one  magnesium  atom  on  the  reactant's side and two on the product's side. Therefore, multiply the magnesium atom by 2 on the left hand side.

 

Component

Reactant

Product

Magnesium

1 x 2 = 2

2

Oxygen

2

2

 

 

Therefore, the number of atoms of each element of reactants = The number of atoms of each element of products.

Acids: The word ‘Acid’ came from Latin word ‘Acidus or Acere’ which means sour.

Sour taste is the most common characteristic of acid. Acid turns blue litmus paper red. There are many substances which contain acid and hence taste sour, such as curd, tamarind, lemon, etc.

Reaction of acids with metal:

Acids give hydrogen gas along with respective salt when they react with a metal.

Metal + Acid → Salt + Hydrogen

Example: Hydrogen gas and zinc chloride are formed when hydrochloric acid reacts with zinc metal.

Zn + 2HCl →ZnCl2 + H2

Reaction of acids with metal carbonate:

Acids give carbon dioxide gas and respective salts along with water when they react with metal carbonates.

Metal carbonate + Acid → Salt + Carbon dioxide + Water

Examples: Hydrochloric acid gives carbon dioxide gas, sodium chloride along with water when it reacts with sodium carbonate.

Na2CO3 + 2HCl → 2NaCl + CO2 + H2O

The temperature coefficient (Q10) represents the factor by which the rate (R) of a reaction increases for every 10-degree rise in the temperature (T). The rate (R) may represent any measure of the progress of a process.
