Answer: I don't know if this helps but here's some information I think might help.
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours. Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) and dividing each by the total number of cells you counted. How do cancer cells differ in total time required for mitosis? Cancer cells produce 117 minutes faster than regular cells. ... Normal cells require 640 minutes during interphase, cancer cells only need 380. For prophase, cancerous cells need 15 minutes less than regular cells. Another hallmark of cancer cells is their "replicative immortality," a fancy term for the fact that they can divide many more times than a normal cell of the body. In general, human cells can go through only about 40-60 rounds of division before they lose the capacity to divide, "grow old," and eventually die 3.
Answer:
Explanation:
Hello,
In this case, since the reaction between HCl and NaOH is:
We notice a 1:1 molar ratio between the acid and the base, for that reason, in the equivalent point we find:
Thus, in terms of concentrations, we have:
Hence, we solve for the concentration of the acid to obtain:

The moles of Al that is needed to react with 6.34 moles of Fe3O4 is 16.9 moles
<u><em> Explanation</em></u>
<em> </em>8 Al+ 3Fe3O4 → 4 Al2O3 + 9Fe
use of mole ratio of Al: fe3O4 to calculate the moles of Al
The mole ratio of Fe3O4 : Al is 8:3 therefore the moles of Al =
6.34 moles x8/3 = 16.9 moles
Answer:
they can produce large amounts of heat energey
Explanation:
i had the same question hope it helps!!!
The theoretical yield is calculated as follows
write the equation for reaction
that is 2 Zn + I2 ------> 2 znI
then find the moles of Zn used
moles= mass/molar mass
= 125/ 65.4 = 1.911moles
by use of mole ratio between Zn to Zni which is 2:2 the moles of ZnI is also= 1.911moles
theoretical yield is therefore= moles of ZnI x molar mass of znI
= 1.911 moles x 319.2 g/mol = 609.99 grams
