Is MnO a catalyst?
MnO can act as a catalyst in certain reactions, such as the decomposition of hydrogen peroxide. However, its catalytic activity depends on the specific reaction and conditions.
Why do old cars give more carbon monoxide?
Old cars give off more carbon dioxide because they do not have catalytic converters. Catalytic converters act as catalysts, converting dangerous substances such carbon monoxide into harmless compounds.
Which automobile pollution control technology became universally adopted following the Clean Air Act Extension of 1970?
Type your answer here... catalytic converters
Are auto makers responsible for replacing a catalytic converter?
According to the Federal Clean Air Act, all factory-installed catalytic converters on 1995 or later model vehicles are warranted for 8 years or 80,000 miles.
Is NO2 a catalyst?
No, nitrogen dioxide (NO2) is not a catalyst in the traditional sense, as it does not remain unchanged after a chemical reaction. However, it can act as a catalyst in specific reactions, such as the oxidation of carbon monoxide to carbon dioxide in the presence of oxygen. In such cases, NO2 facilitates the reaction but may regenerate during the process. Thus, while it can exhibit catalytic properties, it is not a catalyst in all contexts.
What are examples of anti-catalyst substances?
they are inhibitors of chemical reactions or diminishes the activity of a catalyst. The inhibition is temporary when the poison is adsorbed on the surface of the catalyst in preference to the reactants. The Permanent poisoning is when a covalent bond is formed between the poison and the catalyst.for example volatile sulfur and volatile silicon cause permanent poisoning during many cases. Arsenic are poison to platinum. In the reaction of decomposition of H2O2 by platinum, HCN act as poison. In another case CO act as poison to copper during the reaction of hydrogen and ethylene.
Who discovered RNA can act as its own catalyst?
Thomas Cech and Sidney Altman discovered that RNA can act as its own catalyst, a finding that earned them the Nobel Prize in Chemistry in 1989. Their work demonstrated the catalytic properties of RNA molecules, challenging the traditional belief that only proteins could catalyze biological reactions.
Why v2o5 act as a catalyst?
V2O5 acts as a catalyst because it can provide an active surface for the reaction to occur by adsorbing reactant molecules and providing a pathway for the reaction to proceed. Additionally, the variable oxidation states of vanadium in V2O5 allow it to easily switch between different oxidation states during the catalytic reaction, making it an effective catalyst.
What elements make up catalytic converters?
Catalytic converters primarily contain precious metals such as platinum, palladium, and rhodium, which act as catalysts to facilitate chemical reactions. These metals are typically supported on a ceramic or metallic substrate that provides a large surface area for reactions. The converter also includes various materials to promote the oxidation of carbon monoxide and hydrocarbons and the reduction of nitrogen oxides, ensuring that harmful emissions are significantly reduced before being released into the atmosphere.
Is a enzyme a protein that acts as a catalyst formed?

Yes, they do.
Do enzymes act as catalyst?
Yes, they do.
