2C6H14+_10_O2=_6_CO2+_14_H2O

Answer 2

To balance the chemical equation 2C6H14 + __O2 = __CO2 + H2O, you need to determine the coefficients that go in place of the "". The goal is to make sure that the same number of atoms of each element are present on both sides of the equation. Here's how you can balance the equation:

Step 1: Start by counting the number of atoms for each element on both sides of the equation.

On the left side (reactants): Carbon (C): 6 atoms (2 C6H14) Hydrogen (H): 14 atoms (2 C6H14) Oxygen (O): 2 * x atoms (x O2, where "x" is the coefficient we need to find)

On the right side (products): Carbon (C): 1 atom (CO2) Hydrogen (H): 2 atoms (H2O) Oxygen (O): 2 * y atoms (y CO2 + y H2O, where "y" is the coefficient we need to find)

Step 2: Now, create equations for each element to equate their atoms.

For carbon: 2 * 6 = 1 * y 12 = y

For hydrogen: 2 * 14 = 2 * y 28 = 2y y = 14

For oxygen: 2 * x = 2 * y 2 * x = 2 * 14 2 * x = 28 x = 14

Step 3: Write the balanced chemical equation:

2C6H14 + 14O2 = 12CO2 + 14H2O

Now the equation is balanced, with 2 moles of C6H14 reacting with 14 moles of O2 to produce 12 moles of CO2 and 14 moles of H2O.
