<h2>Practise balancing equations:</h2> <h3>Direction:</h3> <ul><li>In the following equations you will see a blank box before the symbol of each compound and element. Enter the lowest possible number in each box, or leave the box blank if you think the chemical needn't have a number (i.e. the number is equivalent to '1').</li>
<li>When you think the equation is balanced, click on the small button <span style= "color:blue;"><b>"Check answer"</b></span> that appears below it.</li> <lI>If your equation is incorrect, then click the button <span style= "color:blue;"><b> "Reset"</b></span> and try balancing the equation again.</li> <li>In case you are in a hurry or are unable to balance, then click the button <span style= "color:blue;"><b>"Show answer."</b></span></li>
<li>If you want to know the time taken (minutes:seconds) to balance a chemical equation, you click the <span style="color:blue;"><b>"Start"</b></span> button and after balancing the equation, click the <span style="color:blue;"><b>"Stop"</b></span>button. Once, you have noted the time, click the <span style="color:blue;"><b>"Reset Timer"</b></span> button.
