What substances change the speed of your reactions?
Catalysts accelerate chemical reaction. Enzymes are examples of catalysts that speed up reactions in the body.
What are five useful items made by metal catalysts?
Metal catalysts are essential in various industrial processes, and five useful items they help produce include: Ammonia - synthesized via the Haber process using iron catalysts, crucial for fertilizers. Hydrogen peroxide - produced through the anthraquinone process with palladium catalysts, used in bleaching and disinfectants. Biodiesel - created through transesterification of oils using sodium or potassium catalysts, promoting renewable energy. Pharmaceuticals - many drugs are synthesized with the aid of metal catalysts, enhancing efficiency and selectivity in chemical reactions. Plastics - catalysts like titanium and zirconium are used in polymerization processes to produce various polymers for everyday items.
What is the difference between Ziegler Natta and metallocene catalyst?
Ziegler-Natta catalysts are heterogeneous catalysts composed of transition metals and organometallic compounds, while metallocene catalysts are homogeneous catalysts consisting of a single transition metal atom sandwiched between two cyclopentadienyl ligands. Metallocene catalysts are more precise and produce polymers with narrower molecular weight distribution compared to Ziegler-Natta catalysts.
What are examples of platinum?
Some examples of platinum include platinum jewelry, platinum catalysts used in chemical reactions, and platinum electrodes in certain electronic devices. Platinum is also used in the automotive industry for catalytic converters.
What other chemicals besides iron and copper can act as catalysts for the luminol reaction?
Other chemicals that can act as catalysts for the luminol reaction include hemoglobin and horseradish peroxidase. These catalysts can enhance the chemiluminescence produced when luminol reacts with hydrogen peroxide in the presence of an appropriate metal ion.
What has the author Kazuo Hata written?
Kazuo Hata has written: 'New hydrogenating catalysts' -- subject(s): Metal catalysts 'Urushibara catalysts' -- subject(s): Metal catalysts
What are some non-examples of catalyst?
Substances like salt, which do not speed up chemical reactions, are non-examples of catalysts. In addition, compounds that hinder or slow down reactions instead of accelerating them are also non-examples of catalysts. Materials like water or inert gases that do not participate in the reaction are other examples of non-catalysts.
What are some examples of respiration?
Catalysts anzyme living things

What are the examples of heterogeneous and homogeneous?
catalysts which are in the same phase to that of reactants and products
Are transition metal good catalysts?
because of partially filled d orbitol
What are some examples of inorganic catalysts and how do they facilitate chemical reactions?
Inorganic catalysts are substances like metals or metal oxides that speed up chemical reactions without being consumed in the process. Examples include platinum, iron, and nickel. They work by providing an alternative pathway for the reaction to occur, lowering the activation energy needed for the reaction to proceed. This allows the reaction to happen faster and more efficiently.
