Answer:
The correct option is: a chemical reaction between carbohydrates and oxygen to produce carbon dioxide, water, and heat energy
Explanation:
Respiration refers to the catabolic reactions in the cells that produce energy in the form of adenosine triphosphate (ATP) from various nutrients.
An aerobic respiration, is a spontaneous process that involves the use of <u>molecular oxygen (O₂) to produce energy (ATP). In this process, molecular oxygen oxidizes nutrients such as carbohydrates, fats, and proteins; to give carbon dioxide, water and heat energy</u>.
Answer:
12.1-M requires less volume of stock solution.
Explanation:
Hello there!
In this case, according to the foundations of dilution processes, it turns out convenient to remember that the moles of the solute before and after the dilution remains the same; for that reason we use the following equation:
![M_1V_1=M_2V_2](https://tex.z-dn.net/?f=M_1V_1%3DM_2V_2)
Relating the initial and final molarities and volumes. Now, it is seen that V2 is 10.0 mL and M2 is 1.0 M, which means that if we solve for V1 for 12.1 M and 6.0 M, we obtain the following volumes:
![V_1=\frac{M_2V_2}{M_1} \\\\V_1^{12.1M}=\frac{1.0M*10.0 mL}{12.1M}=0.826mL\\\\V_1^{6.0M}=\frac{1.0M*10.0 mL}{6.0M}=1.67mL](https://tex.z-dn.net/?f=V_1%3D%5Cfrac%7BM_2V_2%7D%7BM_1%7D%20%5C%5C%5C%5CV_1%5E%7B12.1M%7D%3D%5Cfrac%7B1.0M%2A10.0%20mL%7D%7B12.1M%7D%3D0.826mL%5C%5C%5C%5CV_1%5E%7B6.0M%7D%3D%5Cfrac%7B1.0M%2A10.0%20mL%7D%7B6.0M%7D%3D1.67mL)
Therefore, since the 12.1-M solution requires less volume of stock solution, it makes sense to use this one as the initial solution.
Best regards!
It’s true you can fide it on quizzes .
Atoms bond to form molecules: Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed.
