Bela made scrambled eggs while camping. she placed the eggs in a pan on the grill, then turned on the flame to apply heat to the pan and the eggs. by applying heat, bela increased the of the eggs. she could measure how much with a thermometer.

Explanation:

Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.

As relation between kinetic energy and temperature is as follows.

        K.E =

So, with increase in temperature there will also occur an increase in kinetic energy which leads to an increase in thermal energy of the substance.

Therefore, we can conclude that by applying heat, Bela increased the thermal energy of the eggs. She could measure how much the temperature increased with a thermometer.

"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"
