i have come up with two answers but i am not sure which one is correct. please help.
Balance the following equation and give the value of the stoichiometric coefficient marked with a question mark.
1. 48 KNO3+ 5C12 H22O11 ? CO2+ 24N2+ 24 K2CO3+55 H2O
a.
To balance the given chemical equation, you need to ensure that there is an equal number of atoms of each element on both sides of the equation.
Let's start by counting the number of atoms for each element on both sides of the equation:
On the left-hand side (reactant side):
- Potassium (K): 48 atoms
- Nitrogen (N): 48 atoms
- Oxygen (O): (3 x 16) + (5 x 12) = 96 atoms
- Carbon (C): (5 x 12) = 60 atoms
- Hydrogen (H): (5 x 22) = 110 atoms
On the right-hand side (product side):
- Carbon (C): 1 atom
- Oxygen (O): 2 atoms
- Nitrogen (N): 24 atoms
- Potassium (K): (2 x 12) = 24 atoms
- Hydrogen (H): (5 x 2) + (55 x 2) = 130 atoms
To balance the equation, match the number of atoms for each element on both sides. Here's the balanced equation:
48 KNO3 + 5 C12H22O11 ā 12 CO2 + 24 N2 + 24 K2CO3 + 55 H2O
As for the stoichiometric coefficient marked with a question mark, it is not mentioned in the question. Therefore, we cannot provide the exact value for that specific coefficient without additional information or context.
