Geologic Illustrations. A map shows a bird's eye view looking down at the earth's surface. ... Often a geologic map will indicate both the type of rock and the age of the rock. A cross section shows the surface of the earth (with or without topography or elevation) and a vertical slice of the earth
An hour is 60 minutes. So you multiple the hot by 60. You get 180 minutes plus the 75 remaining minutes. The answer is 255
I believe that the chemical formula for an acid often begins with H, which means C is your answer.
CₓHₐ + (x+a/4)O₂ = xCO₂ + a/2H₂O
n(CO₂)=4.69 mg/44.01 mg/mmol = 0.1066 mmol
n(H₂O)=1.10 mg/18.02 mg/mmol = 0.06104 mmol
C : H = 0.1066 : 0.06104*2 = 0.1066 : 0.12208 = 1 : 1.1453 = 7 : 8
C₇H₈ + 9O₂ = 7CO₂ + 4H₂O
C₇H₈
