Is platinum a homogeneous?
Platinum complexes are excellent homogeneous catalysts for hydrosilylation of olefins, dienes, and alkynes.
Is platinum a mixture or a compound?
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal.
What is platinum made up of?
Most platinum is derived from a mineral called cooperite, also known as platinum sulfide. Platinum is even found in outer space. “Platinum has also been discovered in heavy concentrations in meteorites — first reported in F. G.
What classifying matter is platinum?
Platinum is the third element of the tenth column in the periodic table. It is classified as a transition metal. Platinum atoms have 78 electrons and 78 protons with 117 neutrons in the most abundant isotope. It is considered to be a precious metal along with silver and gold.
Whats meaning of homogeneous and heterogeneous?
In most technical applications homogeneous means that the properties of a system are the uniform throughout the entire system; heterogeneous (also inhomogeneous) means that the properties change within the system. Any system with two phases like ice and water are said to be heterogeneous.
What platinum means?
Platinum is a symbol of true love, purity, rarity and strength. These qualities of platinum are equivalent to the ideals of eternal true love. All over the world, engagement rings, wedding bands and anniversary rings made in platinum symbolize the everlasting endurance of love.

Is platinum homogeneous or heterogeneous or compound or element?
(a) Platinum is a precious metal, which is an element……..
Is platinum Reactive or nonreactive?
Platinum is a silver-white metal — it was once known as “white gold.” It is extremely resistant to tarnishing and corrosion (which makes it known as a “noble metal”) and is very soft and malleable, making it easy to shape; ductile, making it easy to stretch into wire; and unreactive, which means it doesn’t oxidize and …
What are the chemical properties of platinum?
Is platinum a pure solid or liquid?
This element is a solid. Platinum is classified as a “Transition Metal” which are located in Groups 3 – 12 of the Periodic Table. Elements classified as Transition Metals are generally described as ductile, malleable, and able to conduct electricity and heat.
What is heterogeneous and homogeneous definition?
Heterogeneous and Homogeneous Definition. What is a Homogeneous Mixture? These are the types of mixtures in which the components mixed are uniformly distributed throughout the mixture or in other words “the same throughout”. We can observe only one phase of matter in a homogeneous mixture.
What are the characteristics of heterogeneous mixture?
Heterogeneous mixture. It has a uniform composition. It has a non-uniform composition. It has only one phase. There are two or more phases. It can’t be separated out physically. It can be separated out physically. ‘homo’ means the same. ‘hetero’ means different.
How can we judge a homogeneous mixture by seeing it?
We can’t judge a homogeneous mixture by just seeing it; Homogeneous mixtures are also called solutions; Uniform composition; Example: rainwater, vinegar, etc. What is Heterogeneous Mixture? This is a type of mixture in which all the components are completely mixed and all the particles can be seen under a microscope.
Is a soft drink homogeneous or heterogeneous mixture?
In a homogeneous mixture, all the components are uniformly distributed and in the soft drink, we find components like sweetener, carbon dioxide and water forming a single phase. Therefore, a soft drink is a homogeneous mixture.
