How does the strength of the bar magnet affect the current in the pickup coil?

The induction of current increases in the coil.

Explanation:

The strength of the bar magnet affect the current in the pickup coil because the magnetic field produced by the bar magnet interfere with the field of he coil. By moving the bar magnet in and out of the coil so induction of electric current will be occurs in the soil. If a bar magnet with more strength is moving in the coil then more current will be induced inside the coil.

"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
