1.21 write word equations and balanced chemical equations to represent the reactions studied in this specification

Word equations have just the names of the reactants and products involved:
Hydrogen + Oxygen > Water
Balanced equations are the symbols of the products and reactants including the numbers of each, there must be an equal number of each element on both sides of the equation, if there are not you can alter this by putting the right number infront of a symbol:
2H + O > H2O

    Balancing Chemical Equation was Nicely Explain.......But Proper Definition is also required on chemical Equation which is given at http://www.ncerthelp.com/text.php?contype=Concept&class_id=10&sub_id=S&chapter_id=CH1&q_no=1

    "2H + O > H2O"
    The actual balanced chemical for water is 2H2 + O2 > 2H2O
    This is because both hydrogen and oxygen are diatomic molecules.
    The same could be said of Carbon Dioxide: C + O2 > CO2
