What is the effect of silver nanoparticles in plastic?
Silver nanoparticles are antibacterial, and when embedded in plastics for use in the medical field, are non-toxic. This makes silver nanoparticles useful in plastic applications such as surgical catheters.
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.
Why are nanoparticles used?
Because they give us an advantage and we can make things that we probably thought wouldn't be possible before. Nanoparticles can be used to make cameras the size of a dust particle which can be used medically to check inside people and see what is going on for example. Nanoparticles also have many more purposes but there are some risks in using them and we aren't aware of all of them.
Why is rock useful to men?
Limestone is the rock that is most useful to modern industrial countries because it is the source for the main ingredient in cement.
What are the functions of minerals in the body?
They are inorganic catalysts in biochemical reactions. They are also useful in electrolyte and water balance, as well as bone formation, collagen formation, and wound healing.

What products of a chemical reaction are not needed?
You think probable to catalysts, but they are useful.
What are silver nanoparticles used for?
Silver nanoparticles are used in antibacterial technology embedded in refrigerators, washing machines, air coolers, air conditioners, vacuum cleaners and air purifiers. This helps in blocking transmission of airborne diseases in humans and increases safety of health.
Are nanoparticles the same as ordanary particles?
No, nanoparticles are particles that are extremely small, typically between 1-100 nanometers in size, whereas ordinary particles are larger. Nanoparticles exhibit unique physical and chemical properties due to their small size, making them useful in various applications such as medicine, electronics, and environmental science.
What is mean by cluster nano particles and the nano particles?
Cluster nanoparticles refer to aggregates of nanoparticles that are grouped together, often exhibiting distinct physical and chemical properties compared to individual nanoparticles. Nanoparticles themselves are tiny particles with dimensions in the nanometer scale (1 to 100 nanometers) and can have unique characteristics due to their small size, such as increased reactivity and surface area. These properties make both individual nanoparticles and their clusters useful in various fields, including medicine, electronics, and material science. The behavior and applications of cluster nanoparticles can differ significantly from those of larger particles or bulk materials.
What is difference between macro and nanoparticles?
Macroscale structures are typically larger, like the size of human hair or larger, while nanoparticles are on the nanometer scale, typically between 1-100 nm in size. Nanoparticles have unique properties due to their small size, such as high surface area to volume ratio and quantum effects, which can make them useful in a variety of applications.
Industrial process which uses a catalyst?
Catalysts increase the speed of a reaction without taking place in the reaction themselves. This is very useful in industry as it means that chemicals can be made much faster through usually slow chemical reactions, and as the catalysts don't take part in the reaction themselves, they can be reused as much as its needed. Examples of catalysts in industries include the use of the biological catalysts enzymes to brake down substrates in baby foods into smaller simpler molecules. Catalysts lower the activation energy required for a reaction to occur. This will mean that more molecules will have the energy to react. Catalysts allow equilibrium to be established quicker. Catalysts in general lower reaction temperatures leading to lower production costs. Catalysts add to cost e.g. palladium in catalytic converters. Catalysts can be poisoned by waste products eg. Sulphur in petrol and oil can reduce the properties of catalytic converters.
In what way is nuclear energy useful?

How did the Phoenicians help spread civilization by?
By producing a useful alphabet which is the basis of today's.
