Question

methanol can be used to prevent certain liquids from freezing in cold weather. methanol is produced when carbon monoxide and hydrogen gas react. consider the following reaction: 3 molecules of carbon monoxide (co) react with 6 molecules of hydrogen (h₂) to produce some amount of methanol (ch₄o). complete the table below. \

$$\begin{tabular}{|c|c|} \\hline chemical element & number of atoms in the reaction \\\\ \\hline h & \\\\ \\hline c & \\\\ \\hline o & \\\\ \\hline \\end{tabular}$$

during this reaction, how many molecules of methanol (ch₄o) are produced?

Explanation:

Part 1: Completing the table (number of atoms)

For Hydrogen (H):

Step1: Analyze H₂ molecules

Each H₂ molecule has 2 H atoms. There are 6 H₂ molecules.
Number of H atoms = \( 6 \times 2 = 12 \)

For Carbon (C):

Step1: Analyze CO molecules

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

For Oxygen (O):

Step1: Analyze CO molecules

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

Part 2: Number of methanol (CH₄O) molecules produced

Step1: Determine the balanced reaction

The reaction is: \( 3\text{CO} + 6\text{H}_2
ightarrow?\text{CH}_4\text{O} \)

Looking at C atoms: 3 CO molecules have 3 C atoms. Each CH₄O has 1 C atom, so number of CH₄O from C: \( \frac{3}{1} = 3 \)

Looking at H atoms: 6 H₂ molecules have 12 H atoms. Each CH₄O has 4 H atoms, so number of CH₄O from H: \( \frac{12}{4} = 3 \)

Looking at O atoms: 3 CO molecules have 3 O atoms. Each CH₄O has 1 O atom, so number of CH₄O from O: \( \frac{3}{1} = 3 \)

So, the number of CH₄O molecules produced is 3.

Final Table and Answer

Table:

Chemical element	Number of atoms in the reaction
C	3
O	3

Number of methanol molecules:

Answer:

• H atoms: 12, C atoms: 3, O atoms: 3
• Methanol molecules: 3
