Answer:
The surface-to-volume ratio of a C-60 fullerene is 3:77.
Explanation:
Surface area of sphere =
Volume of the sphere =
where : r = radius of the sphere
Radius of the C-60 fullerene sphere = r = 77 pm
Surface area of the C-60 fullerene = ...[1]
Volume area of the C-60 fullerene = ..[2]
Dividing [1] by [2]:
The surface-to-volume ratio of a C-60 fullerene is 3:77.
The answer is C- sulfur hexachlorine (SF6)
<span>S<span>F6 is the only molecule here that is non-polar. That's due to having the</span></span><span> fluorine atoms arranged in a way that, in pairs, they lie opposite to each other. Also, these pairs are perpendicular to each other on three different axis.</span>
I believe it is the dependent variable b/c it is the thing(s) that is been observe or measure
Answer:
Start with the number of grams of each element, given in the problem. the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated.
The answer is c. because you have to increase concentration of h2
