Answer:

C. submicroscopic

Explanation:

I am not sure but I think the best answer here is C, because "submicroscopic" means "too small to be seen by an ordinary light microscope". And because the name of this aparatus sounds so specifically, the answer B - microscopic - not seems to be the best.

"Scanning Tunnelling Microscopy" (STM) is a technique that has been used for the surface study of NANOSTRUCTURES using the chemical composition of atoms and molecules in NPs to image surfaces at atomic level. - This is the definition of STM. It includes the word NANOSTRUCTURES, so the answer C must be the best one.

How many moles of sulfur are needed to produce 15.0 mol of sulfur dioxide?
Brut [27]
<span>S + O2 =  SO2

1 mole S ------------- 1 mole SO2
( moles S ) --------- 15.0 moles SO2

moles S = 15.0 x 1 / 1

moles S = 15.0 / 1

= 15.0 moles S</span>

6. How many half-filled orbitals are in a bromine atom?<br> 1, 2,3,4
lozanna [386]

Answer:

Bromine has one half filled orbital.

Explanation:

The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements. Their boiling points also increases down the group which changes their physical states. i.e fluorine is gas while bromine is liquid and iodine is solid.

Electronic configuration of bromine:

₃₅Br = [Ar] 3d¹⁰ 4s² 4p⁵

As it in known that p sub-shell consist of 3 orbitals px, py, pz and each orbital can accommodate only two electrons.

In bromine there are 5 electrons in 4p it means two electrons are present in px two in py ans one in pz. So the half filled orbital is only one.
