Which of the following is a major difference between lactic acid and alcohol fermentation?
pishuonlain [190]

Both lactic acid and alcoholic fermentation begin with pyruvic acid and nadh. they are anaerobic processes that result in the production of energy in the absence of oxygen. So basically the two differences are that one makes ethanol and one makes lactic acid, and the other is that they are made by different species.


Alcohol fermentation requires aerobic conditions, while lactic acid fermentation requires anaerobic conditions.

For which process is ΔS negative? Group of answer choices A. grinding a large crystal of KCl to powder B. raising the temperatur
ludmilkaskok [199]

Answer:

C.

Explanation:

The entropy (S) is the measure of the randomness of a system, and ΔS = Sfinal - Sinitial. As higher is the disorder of the system, as higher is the entropy.

A. When KCl is fractionated in power, there'll be more portions of it, so, the disorder must be higher, then ΔS is positive.

B. As higher is the temperature, higher is the kinetic energy of the system, and because of that, the disorder is also higher, so ΔS is positive.

C. The decrease in the volume (compression) decreases the distance between the molecules, so the system will be more organized, then ΔS is negative.

D. The volume before the mixing will be higher, and the ethanol will dissociate, so it will be more particles, the disorder will increase, and ΔS is positive.

E. Sgas > Sliquid > Ssolid because of the disorder of the molecules, then ΔS is positive.

If 0.0262 mol of cacl2 is dissolved in water to make a 0.520 m solution, what is the volume of the solution?
Oduvanchick [21]
Cacl2  dissolve   in  water   according  to the  following  equation

Cacl2 + H2O  =  Ca(OH) + Hcl
Volume=  moles/molarity
  The  reacting  ratio    between CaCl2  to  Ca(OH)  is   1:1
therefore  moles  of  solution   is  also  0.0262  moles hence  volume   is  =
0.0262mol/  0.52mol/l =  0.0504L  or50.4ml

PLease help!!! Im in the process of taking my final!!!!! HELPPPPP
Katarina [22]

Answer:

The answer to your question is Aluminum

Explanation:

Number of clues

1.- If this element has 3 rings in its Bohr model, we are looking for and element located in the third period of the periodic table.

For example Sodium, Magnesium, Aluminum, Silicate, Phosphorus, Sulfur, Chlorine and, Argon.

2.- It makes three bonds to become stable, then we are looking for and element located in the third group like

 Boron, Aluminum,  Gallium, Indium, etc

Conclusion

The element that has both characteristics is Aluminum
