Answer:- The gas needs to be transferred to a container with a volume of 11.2 L.
Solution:- From Boyle's law. "At constant temperature, Volume is inversely proportional to the pressure."
It means, the volume is decreased if the pressure is increased and vice versa.
Here, the Pressure is decreasing from 537 torr to 255 torr. So, the volume must increase and calculated by using the equation:
Where, is initial pressure and is final pressure. Similarly, is initial volume and is final volume.
Let's plug in the values in the equation:
(537 torr)(5.30 L) = (255 torr)()
= 11.2 L
So, the new volume of the container needs to be 11.2 L.
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.
Answer:
The answer should be A
Explanation:
because the definition of a subscript is that they indicate the number of atoms of an element present in am molecule or formula unit.
1 mole of particles = 6.02*10²³
8.59 *10²³atoms*(1 mol/6.02*10²³ atoms) = (8.59/6.02) mol
M(Cl)=35.5 g/mol
(8.59/6.02) mol*35.5 g/mol=50.7 g
