Pure platinum is a shiny silver-white color.
Platinum is typically found in nature as a pure metal, rather than in a compound form. It is often mixed with other metals like palladium, rhodium, and iridium in the form of an ore called "platinum group metals."
To find the number of moles in 31.78g of Boron, we first need to determine the molar mass of Boron, which is approximately 10.81 g/mol. Then, we can use the formula: Number of moles = Mass (g) / Molar mass. So, for 31.78g of Boron, the number of moles would be 31.78g / 10.81 g/mol = 2.94 moles.
No, platinum used in jewelry is typically an alloy that contains other metals like copper, titanium, or cobalt to enhance its durability and strength. Pure platinum (often labeled as 99.95% pure) is too soft for everyday wear, so these alloys are added to make the jewelry more resistant to scratches and dents.
Platinum (Pl) is not a mixture. It is an element. It consists only of itself.
All of the moles of pure acid will have dissolved in the flask.
Platinum is an element, so it is "pure".
Pure soda has no sugar.
Pure platinum is a shiny silver-white color.
The number of atoms in 1,2 moles of pure aluminum is 7,2265690284.1023.
It is the purity of the platinum. 850 is 85% pure. 900 is 90% pure. 950 is 95% pure.
Sodium in its elemental form is just sodium metal, Na. Thus assuming that the sample of sodium is pure, there are 2.50 moles of sodium in a 2.50mol sample.
Platinum exist in the nature as pure platinum, in alloys or as compounds (sulfides, arsenides).
