1. Mixing Water at Two Temperatures a. One flask contains 150.0 g water at 20.0 °C. A second flask contains 350.0 g water at 95.0 °C. If the two water samples are mixed, what will the final temperature of the water be?
-Assume that the density of water it 1.000 g/cm^3
-The specific heat capacity for water is 4.184 J/g °C​

Explanation:

Hello!

In this case, since this a problem in which the cold water is heated by the hot water, we can write:

Thus, by plugging in the mass, specific heat and temperatures, we obtain:

Now, we can also write:

Then, after applying some algebra, it is possible to obtain:

If we plug in, we obtain:

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
