What does a newly developed “molecular fence” help convert carbon dioxide into?
• Ethylene
• Oxygen
• Water
• Methane
How does a molecular fence help produce ethylene more efficiently?
• It creates an enclosed environment for reaction intermediates
• It increases the temperature of the reaction
• It provides additional catalytic material
• It removes impurities from the reaction
What amount is cut from science programs in the White House’s proposed budget?
• $73 billion
• $37 billion
