13. 14. 15. 16. Explanation:13. To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. In this case, we have 2 nitrogen atoms and 5 oxygen atoms on the left side, and 1 hydrogen atom and 3 oxygen atoms on the right side. To balance the oxygen atoms, we need to multiply the number of molecules by 4. This gives us 4 hydrogen atoms and 12 oxygen atoms on the right side. To balance the hydrogen atoms, we need to multiply the number of molecules by 1. This gives us 2 hydrogen atoms and 5 oxygen atoms on the left side. Therefore, the balanced equation is .14. In this equation, we have 2 chromium atoms, 4 chlorine atoms, and 12 oxygen atoms on the left side, and 3 chromium atoms, 4 oxygen atoms, and 6 chlorine atoms on the right side. To balance the chromium atoms, we need to multiply the number of molecules by 3. This gives us 3 chromium atoms and 12 oxygen atoms on the right side. To balance the chlorine atoms, we need to multiply the number of molecules by 2. This gives us 4 chlorine atoms on the right side. Therefore, the balanced equation is .15. In this equation, we have 1 calcium atom and 2 arsenic atoms on the left side, and 2 calcium atoms and 2 arsenic atoms on the right side. To balance the calcium atoms, we need to multiply the number of molecules by 3. This gives us 3 calcium atoms on the left side. To balance the arsenic atoms, we need to multiply the number of molecules by 2. This gives us 2 arsenic atoms on the left side. Therefore, the balanced equation is .16. In this equation, we have 3 sodium atoms, 3 carbon atoms, and 2 aluminum atoms on the left side, and 2 sodium atoms, 1 aluminum atom, and 3 carbon atoms on the right side. To balance the sodium atoms, we need to multiply the number of molecules by 2. This gives us 6 sodium atoms on the right side. To balance the aluminum atoms, we need to multiply the number of molecules by 1. This gives us 1 aluminum atom on the right side. To balance the carbon atoms, we need to multiply the number of molecules by 3. This gives us 3 carbon atoms on the left side. Therefore, the balanced equation is .
