what is the difference between combination reaction and decomposition reaction?give one example of each
A student dropped few pieces of marble in dilute HCl contained in a test tube. The gas evolved was passed through lime water. What change would be observed in lime water ? Write the chemical equation for both the changes observed.
explain activity 1.1 , 1.2 ,1.3 , 1.4 , 1.5 , 1.6 , 1.7 ,1.10 , 1.11
Pb(NO3)2 +KI = PbI2 +KNO3
what is the observation?
A white salt on heating decomposes to give brown fumes & a residue is left behind.
(i) Nmae the salt
(ii) Write the equation for the decomposition reaction.
