Answer:
Explanation:
Formal charge of ICl₂⁻
Formal charge = group no - ( no of non bonding electrons +no of bonds)
In I there are 7 electrons in outermost orbit . If we add one more electrons due to - ve charge on the ion , it becomes eight . This centrally placed iodine forms two single bond with two chlorine atoms on either side.
Each of chlorine atoms also contains 7 valance electrons like iodine.
So formal charge of chlorine
= group no - ( no of non bonding electrons +no of bonds)
= 7 - ( 6 + 1 )
= 0
So formal charge of iodine
= group no - ( no of non bonding electrons +no of bonds)
= 7 - ( 5 + 2 )
=0
Formal charge of ICl₂⁺
In this case , central iodine will have only 6 valence electrons due to absence one electron.
So formal charge of chlorine in ICl₂⁺
= group no - ( no of non bonding electrons +no of bonds)
= 7 - ( 6 + 1 )
= 0
formal charge of iodine in in ICl₂⁺
7 - ( 4 + 2)
= 1
Answer:
C.) Alien thickness is mainly affected by temperature. The greater thickness at lower temperatures may be used as a way to stay warmer in colder weather.
Explanation:
Environmental systems.
Considering the Charles' Law, the volume increases from 400 mL to 410.85 mL as the temperature increases from 22.0 °C to 30.0°C.
Charles' Law consists of the relationship that exists between the volume and the temperature of a certain amount of ideal gas, which is maintained at a constant pressure.
For a given sum of gas, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. This is, the volume is directly proportional to the temperature of the gas:
In summary, Charles' law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:
Studying two different states, an initial state 1 and a final state 2, it is fulfilled:
In this case, you know:
Replacing in the Charles's law:
Solving:
410.85 mL= V2
Finally, the volume increases from 400 mL to 410.85 mL as the temperature increases from 22.0 °C to 30.0°C.

Several natural products have been isolated from the flowering plant Sacrostemma acidum, which has been used in folk medicine as a cough suppressant.
Nаturаl products hаd been used by mаny cultures аnd trаditions from thousаnds of yeаrs for their bioаctive phаrmаcophores by modern phаrmаceuticаl compаnies. The potentiаl bioаctive phytocompounds such аs аlkаloids, flаvonoids, phenolic compounds, аnd steroids аre potentiаl source for drug discovery.
Sacrostemma acidum has been used in folk medicine as a cough suppressant. Acidum stem extrаct resulted in аn аrrest of spermаtogenesis without аny systemic side effect. Sperm motility аs well аs sperm density wаs reduced significаntly.

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, Much of the mass of an atom is concentrated in its nucleus. The nucleus contains protons and neutrons and the outer part of the atom contains electrons.
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Electron has -1 charge while proton has +1 charge. Neutron is neutral.
Much of the mass of an atom is concentrated in its nucleus. The nucleus contains protons and neutrons and the outer part of the atom contains electrons.
Therefore, much of the mass of an atom is concentrated in its nucleus. The nucleus contains protons and neutrons and the outer part of the atom contains electrons.
