First we calculate the mass of carbon, hydrogen and oxygen.

Mass of Carbon;<span>
Molar mass of CO</span>₂ is 44.009g/mol  and molar mass of C = 12.011 g/mol 

<span>Mass of Carbon in 14.08g CO2</span>₂ = 12.011/44.009 x 14.08 = 3.84

<span> Mass Hydrogen;
Molar mass H</span>₂O is 18.0015g/mol and molar mass of H is 1.008and  H₂ = 2.016 

<span>Mass Hydrogen in 4.32g of H</span>₂O = 2.016/18.0015 x 4.32 = 0.48

<span> <span>Mass of  Oxygen = total mas of tartaric acid – (mass of carbon + mass of hydrogen) = 12.01 - (3.84+0.48) = 7.69</span>
Now divide carbon, hydrogen and oxygen through their respective atomic masses: </span>
<span>C = 3.84/12.011 = 0.32
<span>H = 0.48/1.008 = 0.48
<span>O = 7.69/15.999 = 0.48
Now divide by smallest: </span>
C = 0.32/0.32 = 1 </span>
H = 0.48/0.32 = 1.5 
O = 0.48/0.32 = 1.5 
multiply by 2 to get whole integers: </span>
C = 1 x 2 = 2 
H= 1.5 x 2 = 3 
<span>O= 1.5 x 2 = 3
<span>Thus, the Empirical formula of tartaric acid = C</span></span>₂H₃O₃

What is a controlled factor in an experiment?
Romashka-Z-Leto [24]
Sorry this will probably be pretty long.

So think of the "control" as being something you yourself add to increase or decrease the effects in an experiment.
I'll give you an example so it is not as confusing.
Say you have decided to make an experiment on plants. Which plant can grow the fastest on which type of liquid? What is being added to this experiment? The liquid! Or all of the liquids you used. Like if you used Coke, Lime Gatorade, Orange Gatorade, and Water. Each drink will EFFECT each plant differently.

How can one describe the bond between the two atoms of hydrogen to the one atom of oxygen within a molecule of water (h2o)?

What does a student need to know about double bonds and triple bonds when predicting molecular geometry of molecules?
zhuklara [117]

This problem is asking for an explanation of what we need to know about double and triple bonds to successfully predict molecular geometries in molecules. At the end, one comes to the conclusion that double and triple bonds contribute to the degree in which an atom is bonded and they also determine the lone pairs, which, at the same time,  define the molecular geometry.

<h3>Molecular geometry:</h3>

In chemistry, molecules are not necessarily flat arrangements of atoms, yet they have specific bond angles, orientations and shapes, which define the molecular geometry. In such a way, we can use the VSEPR theory in order to know the molecular geometry of a molecule; however, we first need its Lewis structure or at least the number and type of bonds to do so.

Consider water and carbon dioxide; the former has two hydrogen to oxygen bonds (O-H) and 2 lone pairs because O has six valence electrons but just 2 are bonded to complete the octet, so 4 unpaired electrons lead to two lone pairs. On the other hand, the latter has two double bonds (C=O) and 0 lone pairs because carbon has four valence electrons and they are all bonded to complete the octet.

In such a way, one can see how the double bond affected the bonding in CO2 in contrast to the H2O; situation that also applies to triple bonds, because CO2 has a linear molecular geometry whereas water has a bent one (see attached picture)

Hence, one comes to the conclusion that double and triple bonds contribute to the degree in which an atom is bonded and they also determine the lone pairs, which, at the same time, define the molecular geometry.
