Complete the equation for the reaction of sulfuric acid and sugar (sucrose). C12H22O11 + 11 H2SO4 ? 12 + 11 H2SO4 + 11
1 answer:
Answer :
The complete equation for the reaction of sulfuric acid and sugar is,
By the stoichiometry of the reaction,
1 mole of sucrose react with the 11 moles of sulfuric acid to give 12 moles of carbon and 11 moles of water.
In this reaction, sulfuric acid react with sucrose (sugar). It dehydrates the sugar molecules which means it eliminates the water.

<h3>Further explanation</h3>
Stoichiometry in Chemistry studies about chemical reactions mainly emphasizing quantitative, such as the calculation of volume, mass, amount, which is related to the number of ions, molecules, elements, etc.
In stoichiometry included :
- 1. Relative atomic mass
- 2. Relative molecular mass
is the relative atomic mass of the molecule
- 3. mole
1 mole is the number of particles contained in a substance with the same number of atoms in 12 gr C-12
1 mole = 6.02.10²³ particles
While the number of moles can also be obtained by dividing the mass (in grams) by the relative mass of the element or the relative mass of the molecule
Luminol (C₈H₇N₃O₂) is a substance used to detect traces of blood in the scene of a crime because it reacts with iron in the blood
a. a luminol stock solution by adding 19.0g of luminol into a total volume of 75.0mL of H2O.
So the molarity is
- 1. Luminol mole
- the relative molecular mass of Luminol
= 8. C + 7.H + 3.N + 2.16
= 8.12 + 7.1 + 3.14 + 2.16
= 177 grams / mol
so the mole:
mol = gram / relative molecular mass
mole = 0.1073
2. Molarity (M)
M = mole / volume
M = 1,431
- b. luminol concentration in a spray bottle 6.00 × 10⁻² M. So that in 2 L of solution, the number of moles is:
mole = M x volume
mole = 6.10⁻² x 2
mole = 0.12
- c. Molarity of the stock solution (Part A) = 1,431 M
the number of moles present in the diluted solution (Part B) = 0.12
So the volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B) is:
volume = mol / M
volume = 0.08386 L = 83.86 ml
