Fermentation is a complex chemical process of making wine by converting glucose C6H12O6 into ethanol C2H5OH and carbon dioxide: C6H12O6(s) ---> 2 C2H5OH (l) + 2 CO2(g) Calculate the mass of ethanol produced if 500.0 grams of glucose reacts completely.

Explanation:

First, we have to check if the reaction is balanced:

We have 6 carbon atoms on both sides, 12 hydrogens, and 6 oxygens. So, we can continue with the problem. If we want to calculate the mass of ethanol () we need to know:

1) Molar mass of glucose ()

In this case, we have to know the atomic mass of each atom:

-) C 12 g/mol

-) O 16 g/mol

-) H 1 g/mol

With the formula we can calculate the molar mass:

(12*6) + (16*6) + (1*12) = 180 g/mol

2) Molar ratio between glucose and ethanol

In the balanced equation we have 1 mol of and 2 moles of . So the molar mass is 1:2

3) Molar mass of ethanol ()

With the formula, we can calculate the molar mass:

(12*2) + (6*1) + (16*1) = 46 g/mol

Finally, we can to the calculation:

I hope it helps!

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
