SCORPION-xisa [38]4 years ago

Answer:

Explanation:

The first two answers are the correct ones. Sometimes C can be true, but it is not a condition. Some equations produce many more products than reactants and some equations are made from more reactants than products.

The last one is normally not true, but the three equations I choose below do give D to be true. Still it does not happen all the time.

C8H18 + 12.5 O2  ===> 8CO2  + 9H20    This is the combustion equation that drives your engine. The coefficients do not add.

Same number of reactants as products.

CH4 + 2O2 ==> CO2 + 2H2O

More products than reactants.

Cu + 4HNO3 ==> Cu(NO3)2 + 2NO2 + 2H2O

More Reactants than products.

H2 + I2 ==> 2HI
