Explanation:
Here I send you all the 3 elements that you are asking for.
Notice that first on the left you will find lewis structure, then condensed and finally chemical formula of each of the compound you enlisted.
The answer is c because thats the number when combined with a metal. +1 is when its combined with a nonmetal.
The formula of alcohol are
1.913 g CO2/44 = 0.043 moles of CO2*12 = 0.043 moles of C 1.174 gram H2O/18 = 0.065 moles of H.
O: 1 - 0.516 g C - 13 g H = 0.354 g O/16 = 0.022 moles of O.
we have 0.043:0.130.;0.022 as C:H:O. Diving by the smallest no. 0.022 we get 1.95:5.9:1 or 2:6:1 as C:H:O.
hope this help

The proper science is validated by Experimentation and Testing .
What is experiment and testing?
Experiment is performed to support or Refuge a hypothesis which is given by someone.
Test is to figure out what we expect and what we have observed.
So , the proper validation of science is Experiment and testing because science is all about hypothesis, discoveries if want to prove them right or wrong we have to perform experiment and test .
