thank you so much both of you i am today iis my happiest day that farzeen sister and atul sir you both helping me .. my next question was balancing of chemical equations??

Answer:
IT'S MY PLEASURE TO HELP YOU SISTER..!
An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
______________________________
Balance equations:-none of atoms of each element on reactants is equal to no of atoms of each element in product You can balance equations by giving numerical digits on elements

Answer:
A chemical equation is a way to predict the way that two or more chemicals will work together. Using what chemists know about the way chemicals act, we add the letter symbols together just like a math problem. In this way we can correctly guess if we will get a new chemical when we mix two or more chemicals together, and what that chemical will be.
Chemical equations are either worded or written using the elements' symbols, how much of the element and in what state (solid[s], liquid[l], gas[g]) it is in.
For example: An aqueous solution of sodium chloride (NaCl[aq]) and another aqueous solution of silver nitrate (AgNO3[aq]). These mixed together form sodium nitrate (NaNO3[aq]) and silver chloride (AgCl[s])
Which in symbols is:
NaCl(aq) + AgNO3(aq) → NaNO3(aq) + AgCl(s)
The solutions formed the solid AgCl. This formation can be called a precipitate and the reaction between the two solutions a precipitation reaction, because the solid produced is not dissolved, whereas all the other products are dissolved.
