Which of the following is an organic compound?
salt
chicken
water
silver

chicken

Explanation:

Organic compounds are compounds that contain carbon. Neither salt (NaCl), water (H₂O), nor silver (Ag) contain carbon.

Chicken is the option which most closely answers the question, but chicken is not a compound. Chicken is made of many different organic compounds, including proteins and carbohydrates.

"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"
