Answer:  Assuming 25 is 25C, 54.9C

Explanation:  The specific heat of zinc is 0.388 J/gC.  With 195 grams, we see that for the whole tray, the temperature will change by 1 C for every 75.66J, since (0.388J/gC)*(195g) = 75.66 J/C.

Thus, (2260J)/(75.66J/C) = 29.9 C increase.  Add that to 25 to yield 54.9 C (or K, if the 25 was in Kelvin).

Divide the grams by 25 to 195 then times it in decimal

zheka24 [161]

Answer:

C. All electron carriers are mobile and hydrophobic

Explanation:

Hello,

In this case, it is widely known that the electron carriers move inside the inner mitochondrial membrane and consequently move electrons from one to another. In such a way, they are mobile, therefore they are largely hydrophobic as long as they are inside the membrane.

For instance, the cytochrome c is a water-soluble protein in a large range, therefore, the answer is: C. All electron carriers are mobile and hydrophobic.

Best regards.

The following charges on individual oil droplets were obtained during an experiment similar to Millikan's. Determine a charge fo
RSB [31]

Answer:

- 1.602 x 10⁻¹⁹coulombs

Explanation:

Charge on individual oil droplet would be multiple of charge on one electron . So we will find out the minimum common factor of given individual charges that is the LCM of all the charges given.

LCM of given charges like 3.204 , 4.806 ,8.01 and 14.42 . We have neglected the power of ten( 10⁻¹⁹)  because it is  already a common factor to all.

The LCM  is 1.602 . So charge on electron is 1.602 x 10⁻¹⁹.
