C6H12 + 9O2 ---> 6 CO2 + 6H2O
C6H12 + 12O2 ----> 6CO2 + 12H2O
which is correct?
also this one
Al2(CO3)3 -->>> Al2O3 + 3CO2
2Al2(CO3)3----->>2Al2O3 + 6CO2
Which is right? what is the difference?
#1 on 1
#1 on 2. Actually, both of the two last ones are balanced but the second one is just twice the first one. The correct one ALWAYS will be the smallersmallest set of coefficients.
thanks for the help!
To determine which equation is correct, we need to balance the chemical equation. Balancing a chemical equation involves making sure that the number of atoms of each element is the same on both sides of the equation.
Let's start with the second equation:
C6H12 + 12O2 ----> 6CO2 + 12H2O
On the left side of the equation, we have 6 carbon atoms in C6H12 and 12 carbon atoms in CO2. On the right side of the equation, we also have 6 carbon atoms in CO2. So, the number of carbon atoms is balanced.
On the left side of the equation, we have 12 hydrogen atoms in C6H12 and 24 hydrogen atoms in H2O. On the right side of the equation, we have 12 hydrogen atoms in H2O. So, the number of hydrogen atoms is balanced.
On the left side of the equation, we have 24 oxygen atoms in O2 and none in C6H12. On the right side of the equation, we have 12 oxygen atoms in CO2 and 12 in H2O. So, the number of oxygen atoms is not balanced.
To balance the equation, we need to multiply the coefficients by certain numbers. In this case, we need to multiply the coefficient of O2 by 2 to obtain 24 oxygen atoms on both sides of the equation:
C6H12 + 12O2 ----> 6CO2 + 12H2O
Now, the equation is balanced, and the second equation is correct.
