Balancing Chemical Equations

Directions:Balance each equation by placing a coefficient in each location. Below is an example. EXAMPLE: #1 2 1 2 #2 1 1 2 #3 2 2 1 #4 4 3 2 #5 2 3 1 #6 1 2 1 2 #7 3 2 2 #8 2 2 3 1 #9 2 5 1 #10 2 1 2 2 Directions:Predict the mass of what is missing. Type in the number only. See the example below. EXAMPLE: Don't forget to double-check your answers before submitting! #1 50 Look at the chemical equation below. Which substances are the reactants and which are the products?Mg + Cl2 --> MgCl2 Reactants Mg Cl2 Products MgCl2 Look at the chemical equation below. Which substances are the reactants and which are the products?H2O2 --> H2O + O2 Reactants H2O2 Products H2O O2 What is the Law of Conservation of Mass? How does a chemical equation exhibit that law? You have a popsicle in a wrapper. You leave it out to thaw but you forget about it and it melts all the way.How does the mass of the frozen popsicle compare to the mass of the melted popsicle? The mass of the frozen popsicle is greater than the melted popsicle. The mass of the frozen popsicle is less than the melted popsicle. The mass of the frozen popsicle is the same as the melted popsicle. It is impossible to determine. Parts of the Chemical Equation Match the term to the corresponding description. Coefficient the big number that applies to EVERY element in the chemical formula. Subscript the small number that only applies to the element preceding it. Chemical Formula a set of chemical symbols showing the elements present in a compound. Arrow Yield Reactants All of the elements on the left side of the chemical equation. Products All of the elements on the right side of the chemical equation.
