Question

ethanol is a chemical that is used in many hand sanitizers. it is produced when steam reacts with the chemical ethylene. consider the following reaction: 5 molecules of ethylene (c₂h₄) react with 5 molecules of water (h₂o) to produce some amount of ethanol (c₂h₆o). complete the table below. chemical element | number of atoms in the reaction h | blank c | blank o | blank during this reaction, how many molecules of ethanol (c₂h₆o) are produced? blank submit work it out not feeling ready yet? this can help: count atoms and molecules in chemical reactions (100)

Explanation:

Part 1: Completing the table (Counting atoms)

For Hydrogen (H):

Step1: Calculate H from \( C_2H_4 \)

Each \( C_2H_4 \) has 4 H atoms. For 5 molecules: \( 5 \times 4 = 20 \)

Step2: Calculate H from \( H_2O \)

Each \( H_2O \) has 2 H atoms. For 5 molecules: \( 5 \times 2 = 10 \)

Step3: Total H atoms

Sum the two amounts: \( 20 + 10 = 30 \)

For Carbon (C):

Step1: Calculate C from \( C_2H_4 \)

Each \( C_2H_4 \) has 2 C atoms. For 5 molecules: \( 5 \times 2 = 10 \)

For Oxygen (O):

Step1: Calculate O from \( H_2O \)

Each \( H_2O \) has 1 O atom. For 5 molecules: \( 5 \times 1 = 5 \)

Part 2: Molecules of ethanol produced

The reaction is \( C_2H_4 + H_2O
ightarrow C_2H_6O \) (balanced). The ratio of \( C_2H_4 \) : \( H_2O \) : \( C_2H_6O \) is 1:1:1. Since we have 5 molecules of each reactant, we produce 5 molecules of ethanol.

Answer:

s for the table:

• H: \( \boldsymbol{30} \)
• C: \( \boldsymbol{10} \)
• O: \( \boldsymbol{5} \)
