​Acetylene is unstable at pressures above ____ psig.Group of answer choices​30​50​70​100

Breakdown the Problem

1. Identify the stability threshold of acetylene concerning pressure.
2. Review the provided multiple-choice options to determine which is the correct answer.

Relevant Concepts

• Acetylene (C₂H₂) is known to be unstable at certain conditions of pressure. When studying chemical stability, specific thresholds are critical for safety and handling.

Analysis and Detail

• Acetylene is generally considered unstable at pressures above 15 psi (pounds per square inch), which can lead to explosive decomposition.
• We need to determine the highest option given that correlates with acetylene's instability.

Verify and Summarize

• Reviewing the options: 30 psig, 50 psig, 70 psig, and 100 psig.
• The correct answer would be the lowest option above 15 psi that is generally known for stability issues.

Final Answer

The answer is 30 psig, as acetylene becomes unstable at pressures above this threshold.
