A balanced equation is an equation where both sides are equal to the same amount The answer to the expression on the left side of the equals sign should be equal to the value on the right side of the equals sign In an unbalanced equation either the left hand side of the equation has a greater value than the right hand side like the example below Good job You completed the quiz so you got practice balancing equations However you missed some questions so you might want to review the steps to balancing equations or print free practice worksheets If you feel ready to move on learn about mass relations in balanced equations Are you ready to try another quiz
Explain your answer 7 As a group play level 1 of the balancing equation game Write down the strategies your group uses to balance chemical equations 8 Start level 2 of the balancing equation game Take turns in your group to balance the equations in the sim using your strategies from Level 1 and adding new strategies as needed 5 2 10 2 5 10 10 10 yes The numbers of N and O atoms on either side of the equation are now equal and so the equation is balanced Exercise 4 1 1 4 1 1 Write a balanced equation for the decomposition of ammonium nitrate to form molecular nitrogen molecular oxygen and water

Tips for Balancing Equations When balancing equations remember chemical reactions must satisfy conservation of mass Check your work to make certain you have the same number and type of atoms on the reactants side as on the products side A coefficient number in front of a chemical is multiplied by all the atoms in that chemical CHALLENGE QUESTIONS BALANCE THE EQUATIONS BELOW A NaNO3 PbO Pb NO3 2 Nazo B Ca3P2 H2O Ca OH 2 PH3 C Fe2O3 CO Fe CO2 D NH3 02 NO2 H20 E FeS 02 Fe2O3 SO2 F C3H602 02 CO2 H20 This problem has been solved
N2 H2 NH3 On the left there is 2 N and 2 H On the right there is 1 N and 3 H If we tried to balance starting with H you d need to use a fraction or decimal and would get messy so let s start with N There s 2 on the left and 1 on the right so we need to change the coefficient of NH3 to 2 Now we have Simply putting her to the equation is balanced now coming to the second equation Here we have 3 calcium here 1 calcium So let us put here 3 now here we have 1 plus 2 pope 1 phosphorus Let us here to phosphor calcium became balanced now coming hydrogen here 32632 z 6 point so 6 Hydrogen means 126 plus 612 means
