The periodic table shows that a carbon atom has six protons. This means that a carbon atom also has
*
O Six electrons
An atomic mass that equals six
O Six neutrons
O
More protons than electrons

A carbon atom has six protons. This means that a carbon atom also has

a) Six electrons

b) Six neutrons

Explanation:

"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"

just did the assignment and the answer was #1 +2 n
