How many atoms of carbon (C) are present in the reactants of the following chemical equation?
C7H16+O2→CO2+H2O(1 point)
A)23
B)7 (i'm thinking its this one but not sure)
C)16
D)1
correct -- that C7 is a big clue
To determine the number of carbon atoms (C) in the reactants of the chemical equation, you need to analyze the subscripts in the chemical formula.
In the given chemical equation, C7H16 represents heptane, which contains 7 carbon atoms. Therefore, the reactant C7H16 contains 7 carbon atoms.
So, the correct answer is B) 7.
To determine the number of carbon atoms present in the reactants, we need to count the number of carbon atoms in the molecule C7H16.
In C7H16, there are 7 carbon atoms because the subscript "7" refers to the number of carbon atoms in the molecule.
Therefore, the correct answer is B) 7.
