MY NOTES ASK YOUR TEACHER Consider a different titrant for this exercise. Suppose Ca(OH)2 were used as the titrant, instead of NaOH. This will make the titrant twice as concentrated in hydroxide ion. The analyte will still be HC2H3O2. (a) What is the stoichiometry of HC2H3O2 to Ca(OH)2

Answer from: brittanysanders

The stoichiometry of the reaction is 1:2.

Stoichiometry shows mass - mole relationship. Mass - mole relationships are very important in chemical arithmetic. All calculations in stoichiometry are based on the balanced chemical reaction equation.

The reaction equation for the reaction between Ca(OH)2 and HC2H3O2 is shown as follows; Ca(OH)2(aq) + 2HC2H3O2(aq) > Ca(C2H3O2)2(aq) + 2H2O(l). The stoichiometry of the reaction is 1:2.

Answer from: kaylienguyen

The stoichiometry of HC₂H₃O₂ to Ca(OH)₂ is 1 : 2

To obtain the stoichiometry of HC₂H₃O₂ to Ca(OH)₂, we shall write the equation for the reaction. This is given below:

HC₂H₃O₂ + Ca(OH)₂ —> Ca(C₂H₃O₂)₂ + H₂O

The above equation can be balanced as follow:

There are 2 atoms of C on the left side and 4 atoms on the right side. It can be balanced by writing 2 before HC₂H₃O₂ as shown below:

2HC₂H₃O₂ + Ca(OH)₂ —> Ca(C₂H₃O₂)₂ + H₂O

There are a total of 10 atoms of H on the left side and a total of 8 atoms on the right side. It can be balanced by writing 2 before H₂O as shown below:

2HC₂H₃O₂ + Ca(OH)₂ —> Ca(C₂H₃O₂)₂ + 2H₂O

Now, the equation is balanced.

From the balanced equation above, the mole ratio of HC₂H₃O₂ to Ca(OH)₂ is 1 : 2

Therefore, the stoichiometry of HC₂H₃O₂ to Ca(OH)₂ is 1 : 2

Answer from: Quest

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
