Balance the following Chemical equations - 
  1. CO2 + H2O → C6H12O6 + O2
  2. SiCl4 + H2O → H4SiO4 + HCl
  3. Al + HCl → AlCl3 + H2
  4. Na2CO3 + HCl → NaCl + H2O + CO2
  5. C7H6O2 + O2 → CO2 + H2O
  6. Fe2(SO4)3 + KOH → K2SO4 + Fe(OH)3
  7. Ca3(PO4)2 + SiO2 → P4O10 + CaSiO3
  8. KClO3 → KClO4 + KCl
  9. Al2(SO4)3 + Ca(OH)2 → Al(OH)3 + CaSO4
  10. H2SO4 + HI → H2S + I2 + H2O






Solution :- 

1. 6CO2 + 6H2O → C6H12O6 + 6O2
2. SiCl4 + 4H2O → H4SiO4 + 4HCl
3. 2Al + 6HCl → 2AlCl3 + 3H2
4. Na2CO3 + 2HCl → 2NaCl + H2O + CO2
5. 2C7H6O2 + 15O2 → 14CO2 + 6H2O
6. Fe2(SO4)3 + 6KOH → 3K2SO4 + 2Fe(OH)3­-
7. 2Ca3(PO4)2 + 6SiO2 → P4O10 + 6CaSiO3
8. 4KClO3 → 3KClO4 + KCl
9. Al2(SO4)3 + 3Ca(OH)2 → 2Al(OH)3 + 3CaSO4
10. H2SO4 + 8HI → H2S + 4I2 + 4H2O

          SQUARES AND SQUARE ROOTS   Square number - The square of a number is the product of the number with the number itself.  A given number is a perfect square if its prime factors can be expressed in pairs of equal factors.  A perfect square number is never negative. For example - 8^2 = (8×8) = 64 Facts About Squares -  1. A number ending in 2, 3, 7 or 8 is never a perfect square.  2. A number ending in an odd number of zeros is never a perfect square.  3. The square of an even number is always even.  4. The square of an odd number is always odd.  5. The ending digits of a square number is 0, 1, 4, 5, 6, or 9 only.  Note:- It is not necessary that all numbers ending with digits 0, 1, 4, 5, 6, or 9 are square numbers.  Important Facts-  1. Numbers ending in an even number of zeros are not necessarily perfect squares. Eg- 3700, 290000, 47000000.   Practice Questions :-  1. Find the square of 54 ?  2. What least number must be added to 5607 to mak
