Write the complete balanced equation for the following reaction: (3 points) ch3ch2oh + o2 yields co2 + h2o

  CH3CH2OH + O2 → CO2 + H2O 
The reaction above is combustion of a compound with C, H, and O. 
The following method will balance any combustion equation of CxHyOz. 

1st balance the C’s 
2 C’s on left, 2 C’s on right. Make 2 C’s on right, by making 2 CO2’s on right. 

CH3CH2OH + O2 → 2 CO2 + H2O 

2nd balance the H’s 
6 H’s on left, 2 H’s on right. Make 6 H’s on right, by making 3 H2O’s on right. 

CH3CH2OH + O2 → 2 CO2 + 3 H2O 

3rd balance the O’s 
You do not want to change the coefficient of CH3CH2OH. So, balance the O’s on the right by changing the coefficient of O2. 
4 O’s + 3 O’s = 7 O’s on right. Make 3 O2’s on left. 

CH3CH2OH + 3 O2 → 2 CO2 + 3 H2O 
Check: 
2 C’s = 2 C’s 
3 + 2 + 1 H’s = 3 * 2 H’s 
1 + (3 * 2) O’s = (2 * 2) + 3 O’s 

If the coefficient of O2 is a fraction, you multiply both sides of the equation by the denominator of the fraction. 
Example: 
C4H10 + O2 → CO2 + H2O 
The coefficient of CO2 is equal to the number of C’s in the reactant = 4 
C4H10 + O2 → 4 CO2 + H2O 
The coefficient of H2O is equal to ½ of the number of H’s in the reactant = 5 
C4H10 + O2 → 4 CO2 + 5 H2O 
Right side has 8 + 5 = 13 O’s. Make 6.5 O2. 
C4H10 + 6.5 O2 → 4 CO2 + 5 H2O 

4th double the entire equation so all coefficients are whole numbers 

2 C4H10 + 13 O2 → 8 CO2 + 10 H2O

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
