Enter your answers in the gaps. You did so well on this quiz you could tutor others on how to balance equations. They range in difficulty level so dont get discouraged if some of them seem too hard.
The first step to balance the equation is to write down the chemical formula of reactants that are listed on the left side of the chemical equation. 2NaHCO 3 Na 2 CO 3 CO 2 H 2 O 32. Stoichiometry is a section of chemistry that involves using relationships between reactants andor products in a chemical reaction to determine desired quantitative data.
Check your answers and then write the balanced equations. When balancing equations remember chemical reactions must satisfy conservation of mass. Unlike when we balance equations in class you will have to include coefficients of one by typing in a value of 1 When you have entered all the answers click on the Check button.
