The answer is Ne Neon!!!!!!!!!!!!!!
<u>Answer:</u> The concentration of HBr sample is 0.1025 M
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is HBr
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of HBr sample is 0.1025 M
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:
1 moles Calcium Fluoride = 78.0748064 gram using the molecular weight calculator and the molar mass of CaF2.
<span>Fields surrounding a stationary charge produces an electric field and fields surrounding a smoving charge produces a magnetic field and this magnetic field force cant perform any work because it is perpendicular to the field(B) and velocity(V) but electric field force can perform work</span>
