It seems that you have missed the given image to answer this question. But anyway, I found it and got the answer. Based on the  topographical map of a section of Charleston, SC, the feature that is <span>located at the dot marked with an X is the high point of a hill. The answer would be option D.</span>
        
             
        
        
        
Answer:
2Na + Br2 = 2NaBr
Explanation:
In order to balance a chemical equation you make the make sure both sides have the same number of atoms on each side, you do this by multiplying on both sides as if it was a algebraic equation.
Na+ Br2 = NaBr
Na × 2 = Na2
Na × 2 = Na2
Br × 2 = Br2
2Na + Br2 = 2NaBr
Hope this helps.

Answer:
Ammonia is limiting reactant
Amount of oxygen left  = 0.035 mol
Explanation:
Masa of ammonia = 2.00 g
Mass of oxygen = 4.00 g
Which is limiting reactant = ?
Balance chemical equation:
4NH₃ + 3O₂     →     2N₂ + 6H₂O
Number of moles of ammonia:
Number of moles = mass/molar mass
Number of moles = 2.00 g/ 17 g/mol
Number of moles = 0.12 mol
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 4.00 g/ 32 g/mol
Number of moles = 0.125 mol
Now we will compare the moles of ammonia and oxygen with water and nitrogen.
                       NH₃          :            N₂
                         4             :             2
                       0.12           :           2/4×0.12 = 0.06
                       NH₃         :            H₂O
                         4            :             6
                         0.12       :           6/4×0.12 = 0.18
                        
                        O₂            :            N₂
                         3             :             2
                       0.125        :           2/3×0.125 = 0.08
                         O₂           :            H₂O
                         3              :             6
                         0.125       :           6/3×0.125 = 0.25
The number of moles of water and nitrogen formed by ammonia are less thus ammonia will be limiting reactant.
Amount of oxygen left:
                         NH₃          :             O₂
                            4            :              3
                            0.12       :          3/4×0.12= 0.09
Amount of oxygen react = 0.09 mol
Amount of oxygen left  = 0.125 - 0.09 = 0.035 mol
