One glass of water is 85 degrees F and another is 40 degrees F. When an Alka Seltzer tablet is dropped into each glass, at the same time, which of the following describes the expected results? The 85 degree F glass will have an accelerated chemical reaction, because the water was warmer. The 85 degree F glass will have an accelerated chemical reaction, because the water is cooler.

The 40 degree F glass will have an accelerated chemical reaction, because the water is cooler.

The 40 degree F glass will have an accelerated chemical reaction, because the water was warmer.

The 85 degree F glass will have an accelerated chemical reaction, because the water was warmer.

Explanation:

The glass of water with the higher temperature will have an accelerated chemical reaction because the water is warmer.

The rate of chemical reaction is directly proportional to the temperature changes.

As temperature increases so is the reaction rate.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

will have a gram-molecular weight of 352g.
