alcohol a) extremely long molecule chain with repeated molecular units

ether b) contains an oxygen and hydrogen (−o−h) bonded to a carbon

carbonyl group c) contains a carbon atom double-bonded to an oxygen atom

polymer d) contains an oxygen bonded within the carbon chain

The answer to your question is:

Explanation:

Alcohol   B) Contains an oxygen and hydrogen (−O−H) bonded to a carbon

Polymer A) Extremely long molecule chain with repeated molecular units

Ether D) Contains an oxygen bonded within the carbon chain

Carbonyl group C) Contains a carbon atom double-bonded to an oxygen atom

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

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"
