In this equation, stands for carbon, stands for nitrogen, and stands for oxygen. which equation represents this reaction?
a.) 2co + 2no → 2cn2 + o2
b.) co + no → 2co2 + 2n2
c.)2co2 + 2no → co2 + n2
d.)2co + 2no → 2co2 + n2
e.)2co + 2no → 2cn2 + o2

D.) 2CO + 2NO → 2CO2 + N2

Explanation:

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
