For example if Cu(II)SO_{4} is solid (anhidrous) crystal and u add a piece of solid zinc,there would be no chemical reaction... UrbanXrisis said:
A word equation is a written representation of a chemical reaction using words instead of chemical symbols. It shows the reactants on the left side and the products on the right side, with an arrow indicating the direction of the reaction.
A chemical equation uses chemical symbols and formulas to represent a reaction, while a word equation uses words. Chemical equations are more specific and precise, while word equations are easier to understand for those who are not familiar with chemical symbols.
A word equation provides the names of the reactants and products involved in a chemical reaction, as well as the overall direction of the reaction. It does not provide information on the quantities of each substance or the specific conditions of the reaction.
Word equations are important in science because they allow scientists to communicate and understand chemical reactions without needing to know complex chemical symbols and formulas. They also help to visualize and conceptualize the reactants and products involved in a reaction.
To balance a word equation, you need to make sure that the number of atoms of each element is equal on both sides of the equation. This can be done by adjusting the coefficients (numbers in front of the reactants or products) as needed. It is important to note that the subscripts (numbers within a chemical formula) cannot be changed when balancing an equation.
