Answer:
l and t
Explanation:
because they are in group one
Explanation:
IR (infrared) spectroscopy theory is based on the concept that the molecules tend to absorb some specific amount of the frequencies of light which are characteristic of corresponding structure of molecules. These energies are reliant on shape of molecular surfaces, associated vibration coupling, and mass corresponding to atoms.
It is used to detect the type of the functional group present in the organic compound.
Answer:
0.4941, 0.5059
Explanation:
= Partial pressure of nitrogen = 417 mm Hg
= Partial pressure of xenon = 427 mm Hg
Total pressure in the system is given by
Mole fraction is given by
For xenon
or
So, mole fraction of nitrogen is 0.4941 and xenon is 0.5059.

Iodine- 131 ------------------> Xenon -131 + Beta particle
Answer:
[Ar]3d^84s^2
Explanation:
From the question given, we are asked to write the condensed form of electronic configuration of nickel, Ni.
To do this, we simply write the symbol of the noble gas element before Ni in a squared bracket followed by the remaining electrons to make up the atomic number of Ni.
This is illustrated below:
The atomic number of Ni is 28.
The noble gas before Ni is Argon, Ar.
Therefore, the condensed electronic configuration of Ni is written as:
Ni(28) => [Ar]3d^84s^2
