Question

phosgene is a substance that is often used to make the padding found in car and airplane seats. it is produced when carbon monoxide and chlorine gas react. consider the following reaction: 3 molecules of carbon monoxide (co) react with 3 molecules of chlorine (cl₂) to produce some amount of phosgene (cocl₂). complete the table below. chemical element | number of atoms in the reaction c | o | cl | during this reaction, how many molecules of phosgene (cocl₂) are produced? submit work it out not feeling ready yet? this can help: count atoms and molecules in chemical reactions (100)

Explanation:

For the table (counting atoms):

Step 1: Count Carbon (C) atoms

Each CO molecule has 1 C atom. There are 3 CO molecules. So number of C atoms = \( 3 \times 1 = 3 \)

Step 2: Count Oxygen (O) atoms

Each CO molecule has 1 O atom. There are 3 CO molecules. So number of O atoms = \( 3 \times 1 = 3 \)

Step 3: Count Chlorine (Cl) atoms

Each \( Cl_2 \) molecule has 2 Cl atoms. There are 3 \( Cl_2 \) molecules. So number of Cl atoms = \( 3 \times 2 = 6 \)

For the number of phosgene molecules:

Step 1: Write the balanced reaction

The reaction is \( 3CO + 3Cl_2
ightarrow? COCl_2 \)
From the reaction, the ratio of CO to \( COCl_2 \) is 1:1 (since each \( COCl_2 \) has 1 CO unit). Since we have 3 CO molecules, the number of \( COCl_2 \) molecules produced is 3.

Table Completion:

• C: \( \boldsymbol{3} \)
• O: \( \boldsymbol{3} \)
• Cl: \( \boldsymbol{6} \)

Number of Phosgene Molecules:

\( \boldsymbol{3} \)
