PDF Balancing Chemical Equations: Introductory Stoichiometry Worksheet 2B: Balancing Chemical Equations - Chemistry LibreTexts Or you can set the balancing chemical equations worksheet as homework, and keep young minds active when they're away from school. Students simply need to answer a set of chemical balancing questions, and double check that they can complete each of the three learning outcomes listed at the bottom. Balance the equations below: ____ N2 + ____ H2 ____ NH3. ____ KClO3 ____ KCl + ____ O2. ____ NaCl + ____ F2 ____ NaF + ____ Cl2. ____ H2 + ____ O2 ____ H2O. ____ Pb(OH)2 + ____ HCl ____ H2O + ____ PbCl2. ____ AlBr3 + ____ K2SO4 ____ KBr + ____ Al2(SO4)3. ____ CH4 + ____ O2 ____ CO2 + ____ H2O. ____ C3H8 + ____ O2 ____ CO2 + ____ H2O To achieve a balance, we write coefficients in front of each chemical species, although the number 1 is never written as a coefficient. The equation 2 H 2 + O 2 ® 2 H 2 O can be taken to say, "For every two molecules of H 2 , one molecule of O 2 reacts to form two molecules of H 2 O." Balance chemical formulas by placing coefficients in front of them. Do not add subscripts, because this will change the formulas. Indicate the states of matter of the reactants and products. Use (g) for gaseous substances. Use (s) for solids. Use (l) for liquids. Use (aq) for species in solution in water. Balancing Chemical Equations Worksheet | Beyond Science - Twinkl 7.1: Balancing Chemical Equations - Chemistry LibreTexts How to Balance Equations - Printable Worksheets - ThoughtCo Balance the following equations. 1. \(CO_{(g)} + O_2 \rightarrow CO_{2\; (g)}\) 2. \(N_2O_{5 \;(g)} + H_2O_{(l)} \rightarrow HNO_{3 \;(aq)}\) 3. \(CH_{4 \;(g)} + Cl_{2\; (g)} \rightarrow CCl_4(l) + HCl_{(g)}\) 4. \(Al_4C_{3\; (s)} + H_2O_{(l)} \rightarrow Al(OH)_{3 \;(s)} + CH_4\) 5. 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. After this, you can list down the products on the right hand side of the chemical equation. Balancing Chemical Equations Interactive Worksheet By Liveworksheets.

Worksheets. In this article, you will learn about how to balance chemical equations easily with simple steps. Feel free to download our free worksheets with answers for your practice. Balancing equations. During chemical reactions, atoms cannot be created or destroyed. The number of each atom on each side of the reaction must therefore be the same. E.g. the reaction needs to be balanced. When balancing equations remember: Not to change any of the formulae. To put the numbers used to balance the equation in front of the formulae. To balance an equation you work across the equation from left to right, checking one element after another. If there is a group of atoms, for example a nitrate group (NO 3-) that has not changed from one side to the other, then count the whole group as one entity rather than counting the individual atoms.
