How many moles in 31.78G of Boron?
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.
Is boron is shiny?
Pure boron (a metalloid) is not found in nature. Boron will be combined with something else. Pure boron could be shiny, but will usually be a brown powder when combined with carbon.
Is boron a pure substance or mixture?
Boron is a pure substance. It is a chemical element with an atomic number of 5 and is found in nature as a solid.
Is boron malleable ductile or brittle?
Boron is considered brittle in its pure elemental form.
What shape is a pure boron molecule?
A pure boron molecule typically forms a planar triangular structure, known as a borane cluster or boron sheet. These structures can vary depending on how many boron atoms are present and how they are arranged, but they generally exhibit a flat geometry due to the sp2 hybridization of boron atoms.
How do you make a pure sample of fluorine?
No you cannot make a pure sample of Fluorine because it is an earth made element.

Is element boron a pure substance?
no
What is boron's pure element form?
The "pure element form" of boron is a meteorite. Boron isn't very reactive...but since it's formed by cosmic rays it isn't very abundant either.
Is boron malleable ductile or brittle?
Boron is considered brittle in its pure elemental form.
What are the chemicals of boron?
Boron is a pure element with symbol B and atomic number 5.
How do you make a pure sample of rhodium?

What is the correct formula for boron?
Boron is an element, #5 on the periodic chart....so the formula then for pure Boron would be its chemical symbol "B."
