A student tried to predict the products for the following reaction.
Why is the following reaction equation incorrect?
1 H2O --> 1 H2 + 1 O
because oxygen is a diatomic element (O2)
because the equation is not balanced
because this is not a decomposition reaction
because H2O does not have a neutral charge
A student tried to predict the products for the following reaction.
Why is the following reaction equation incorrect?
1 Na + 1 Cl2 --> 1 NaCl2
because chlorine is a diatomic element (Cl2) and should be written as 2 Cl.
because the equation is not balanced
because this is not a synthesis reaction
because NaCl2 does not have a neutral charge and should be written as NaCl
A student tried to predict the products for the following reaction before balancing
Why is the following reaction equation incorrect?
__ C6H12 + __ O2 --> C6H12O6
because the products are CO2 and H2O in a combustion reaction
because this is not a synthesis reaction
because NaCl2 does not have a neutral charge and should be written as NaCl
