nitrogen dioxide (NO2) in the reaction 4NH3 + 702 --> 4NO2 + 6H20?*

5.1 moles
7.7 moles
9.0 moles
16moles

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
