What is the mole ratio between oxygen and carbon dioxide?<br><br> C25H52 + 38 O2 → 25 CO2 + 26 H2O
user100 [1]

Answer:

38 : 25

Explanation:

First thing's first, we have to confirm if the reaction is indeed balanced.

The equation of the reaction is given as;

C25H52 + 38 O2 → 25 CO2 + 26 H2O

From the reaction, 38 moles of O2 produces 25 moles of CO2

The ratio is given as;

38 : 25

Fluorine-18 is a positron emitter used in pet scans. write a balanced nuclear equation for the reaction.
kow [346]
<span>Due to limitations on typography, I will have to describe the equation instead of actually writing it. Crude appearance. 18 18 0 F --> O + e 9 8 1 Detailed description. Each of the 3 components have both a left superscript and a left subscript which is a superscript and a subscript to the LEFT of the main figure unlike the usual right side that you see subscripts and superscripts. The equation will be F with an 18 left superscript and a 9 left subscript to represent Florine with atomic weight of 18 and 9 protons. Followed by a right arrow to indicate the direction the reaction is going. Followed by the letter O with a left superscript of 18 and a left subscript of 8 to represent Oxygen with atomic weight of 18 and 8 protons. Followed by a plus sign to indicate more. Followed by either the lower case letter "e" or the upper case Greek character beta with a left superscript of 0 and a left subscript of 1 or +1 to represent the positron being emitted with a positive charge and an atomic weight of 0.</span>
