Morgan did an experiment to see the effect of water temperature on the rate at which sugar dissolves. she placed a sugar cube in several glasses and added the same amount of water at 3 different temperatures to the glasses. she then observed how long it took the sugar to dissolve in each temperature. how should morgan organize her data?
a. by size of the glass
b. by the water temperature
c. by the amount of sugar placed in each glass
d. by the amount of sugar left in the glass after the experiment

B. By the water temperature

Explanation: Increase in temperature increases the rate of a chemical reaction. The temperature of water in the glass determines how fast or slow the sugar cube dissolves in the water (i.e., the time taken for the sugar cube to dissolve in water).

cock topography

the study of the surface of a large voluptuous cock.

look at that sorostitute right she's a cock topographer!

what classes are you taking this

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
