A skeleton equation in chemistry contains obviously the abbreviations of the elements you are being asked to represent. it may contain the exponents also known as subscripts but it does not include coefficients.
I am sorry but the question is incomplete. You have not mentioned the ordered pairs and the equation is incomplete as well.
A skeleton equation.
A skeleton equation has all the correct reactants and products but it does not have the coefficients that indicate the stoichiometric proportions.
No. An equation can remain unanswered, it may be incomplete and it may be inaccurate.
Incomplete combustion of Methane is....2CH4 + 2O2 --> CO + C + 4H2O
Incomplete combustion of decane is ...2 C10H22 + 21 O2 ==> 20CO + 22H2O
It looks like an incomplete equation.
CO
Incomplete combustion of Methane is....2CH4 + 2O2 --> CO + C + 4H2O
Ba + Br2 ----> BaBr2
the relative amounts of reactions and products
