CH4+202->CO2+2H20 To begin the experiment, 1.65g of methane CH is burned in a bomb calorimeter
containing 1000 grams of water. The initial temperature of water is 18.98°C. The
specific heat of water is 4.184 J/g °C. The heat capacity of the calorimeter is 615 J/
Som After the reaction the final temperature of the water is 36.38°C.

"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  

mgco3-5h2o"

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
