In order to write a word equation to represent a chemical reaction I must: write the name of the reactant (carbonic acid) draw an arrow to show the direction of the chemical reaction, → write the names of each of the products separated by a plus sign (+) to the right of the arrow (carbon dioxide + water)
Solution
When an iron nail is dipped in Copper sulphate solution a displacement reaction takes place, in which one metal displaces the other metal from its salt solution.
Word Equation : Iron + Copper sulphate → Iron sulphate + copper.
Chemical Equation: Fe+CuSO4→Cu+FeSO4
A chemical change will take place when an iron nail is immersed in CuSO4 solution.
write a word equation for the above chemical reaction?
When magnesium burns in air it forms magnesium nitride with nitrogen and with oxygen it forms magnesium oxide.
