Homework Answers
Solution:
correct option D) the number of atoms in each element is the same in reactant and product
Example: Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)
in above equation the number of each atom in reactant is equal to number of atom in product

Fill in the blanks regarding balanced chemical equation. In a balanced chemical equation, all _________ will be equal on either side of the arrow. In a balanced chemical equation, all chemicals ________ are termed "reactants", and all chemicals _________ are termed "products". When balancing a chemical equation, it is acceptable to alter ________ but not _________.

When a chemical reaction occurs, atoms rearrange to form now compounds, but no new atoms are created nor are any destroyed This concept is called conservation of mass. Mass conservation can be seen in a balanced chemical equation where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of element A (lavender spheres) with element B (tan spheres). Write the balanced chemical equation for this...

Why must chemical equations be balanced? In a balanced chemical equation, the coefficients in front of each reactant and product allow us to predict whether the given reaction is possible or not. In a balanced chemical equation, the coefficients in front of each reactant and product allow us to predict whether the reaction requires a catalyst or not. In a balanced chemical equation, the coefficients in front of each reactant and product allow us to predict the amount of product...

Chemical Reactions with Isotopes The coefficients in a balanced chemical equation represent the relative numbers of each molecule or formula unit and the relative number of moles of each molecule or formula unit. In a balanced equation, the stoichiometric relationships among the substances allow us to convert between quantities of reactants and products in a reaction. Deuterium Deuterium (written as D or 2H) is an isotope of hydrogen known as heavy hydrogen. PART A QUESTION: Balance the given chemical equation...
