Reaclant diae rFroauct diae (Left) (Right) Make Ammonia 8 8 Separate Water 6 6 Combust Methane | 9 9 5. Is the number of total atoms on the left side of a balanced equation always equal to the numb of total atoms on the right side of the equation? They are always equal to each other because they are balanced chemical equations 6. What is the same on the left and right side of a balanced equation? Explain your answer. The same amount of each element 7. Play level 1 of the balancing equation game. Write down the strategies you use to balance the chemical equations. Counting the number of each atoms and fixing it. 20f4 BALANCING CHEMICAL EQUATIONS 1 8. Inlevel 1, Write down the equations as you solve them. C+0, — CO, CH,OH — CO + 2H, 2HCI — H; + Cl, 2C0O, - 2CO + 0, 2NH; — N, + 3H, 9. Start level 2 of the balancing equation game. Balance the equations in the sim, using your strategies from Level 1, and adding new strategies as needed. Write down the equations as you solve them. CS; + 30, — CO, + 280, CH,+ 20, — CO, + 2H,0 CH, + H,0 — 3H, + CO 2F; + H,0 — OF, + 2HF C,H; + Cl, — C,H,Cl + HCI 10. In the simulation, were you able to use noninteger numbers (like % or 0.43) for the coefficients in a balanced equation? No Why do you think this is? Because you can't have a part of an atom. a) Which of the following are coefficients you could use in a balanced equation? O% 0% 1 B2 B o9 b) If you were balancing an equation containing the O, molecule, which of the following would be correct representations of O, and its coefficient? O %O, Ho, 30, M 6o, 030 0 50, . What do you have to do to the coefficients of equation I below to get to equation I1? i 25n0,+4H, 2Sn+4H,0 il. Sn0, + 2 H, Sn+ 2H,0 Divide everything by 2 a) Both equation I and Il are balanced, but equation | is the correct way to write the balanced equation. b) Can you divide equation Il by another factor and still have it be correct? Why or why not? No because then you'd get fractions 2 BALANCING CHEMICAL EQUATIONS ¢) Inacomplete sentence, write down a method you could use to determine if an equation is written in the correct way. By counting the amount of amounts in each part of the equation and making sure they are equal. 12. Start level 3 of the balancing equation game. Write down the equations as you solve them, along with any new strategies you need for balancing. 4C0, + 6H,0 — 2C,H, + 70, 4NH, + 30,— 2N, + 6H,0 4NO + 6H,0 — 4NH, + 50, 2C,H, + 50, — 4C0, + 2H,0 ) U NAJ LN AN L2U N
