AP Chemistry 25.5 g of methane burns in the combustion reaction below. How much water is produced in this reaction? CH4 + 202 -- CO2 + 2H20
A. 22.69
B. 57.39
C. 510g
D. 3.18 9

B

Explanation:

CH4 + 2 O2 → CO2 + 2 H20

12 + I X 4 → → 2 ( I X2 + 16 )

16 → → 36

25, 5 → → ?

amount of H2O = 36 X 25,5 / 16 = 57. 39

The following numbers -1.2 and 26 must represent something from the statement "The relationship between antioxidant food consumption per day in cups and the BMI"

y means the amount of BMI

x means the amount of cups

Finally "+26" must mean how many more cups to change the amount of BMI / representing y.
