This type of a reaction is a double displacement reaction. where the reactants displace each other. the cations and the anions the reactant compounds replace each other or in other words switch places. the anion of one compound will bond with the cation of the other compound and vice versa.
the equation for the above is Na₂S + CdSO₄ ---> CdS + Na₂SO₄ the numbers of atoms on both sides are balanced now
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Double displacement reaction is one in which exchange of ions take place.
If a neutral atom has 30 protons and 34 neutrons, the number of electrons in the atom is: A) 94. B) 34. 64. ... 17) What is the symbol for the ion with 19 protons and 18 electrons? A) F+. B) K+ ... 21) Identify the metalloid in the following list. Hope this helps you! Ask me anything if you have any quistions!
