When sugar is burned, water vapor and carbon dioxide are produced.
Natalija [7]

Answer:

12 carbon, 22 hydrogen, 11 oxygen

Explanation:

Our equation is: Sugar + 12O_2  ⇒  11H_2O + 12CO_2

This is already balanced which means that the number of atoms for each type of element on each side should be the same.

On the right side, there are 11 * 2 = 22 hydrogen atoms, 11 * 1 + 12 * 2 = 11 + 24 = 35 oxygen atoms, and 12 * 1 = 12 carbon atoms.

Currently on the left, there are 12 * 2 = 24 oxygen atoms. That means that sugar must have 11 oxygen atoms to balance it out. In addition, since the left side currently has no hydrogen or carbon atoms, those must belong to the sugar molecule.

Thus, the sugar molecule has 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

What is the definition of titration
Setler [38]
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete

Given: 2LiBr + I2 → 2LiI + Br2 Calculate the mass of bromine produced when 9.033 × 1023 particles of iodine (I2) react completel
Llana [10]

Answer:

239.7 g

Explanation:

Step 1: Write the balanced equation

2 LiBr + I₂ → 2 LiI + Br₂

Step 2: Convert the molecules of iodine to moles

We have 9.033 × 10²³ particles (molecules) of iodine. In order to convert molecules to moles, we will use the <em>Avogadro's number</em>: there are 6.022 × 10²³ molecules of iodine in 1 mole of iodine.

9.033 \times 10^{23}molecule \times \frac{1mol}{6.022 \times 10^{23}molecule} =1.500mol

Step 3: Calculate the moles of bromine produced

The <em>molar ratio of I₂ to Br₂</em> is 1:1. Then, the moles of bromine produced are 1.500 moles.

Step 4: Calculate the mass of bromine

The <em>molar mass of bromine</em> is 159.81 g/mol. The mass corresponding to 1.500 moles is:

1.500mol \times \frac{159.81g}{mol} = 239.7 g
