B. Kryptonite
C. Quartz
D. Pyrite
Answer:
one more proton
Explanation:
The symbol for phosphorous is P; it is element 15 on the Periodic Table. That
means phosphorous-31 has 15 protons. The symbol for sulfur is S; it is
element 16 on the Periodic Table. Sulfur-32 has 16 protons.
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
It boosts the loop's flux, which creates a voltage surrounding the loop and moves an electric current through the wire.
A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of passage of electric charge through a surface or into a control container is used to calculate it.
Electrons are moving constantly in current electricity. Direct current and alternating current are the two types of current used in electricity. Electrons travel only in the direction of direct current. Direct current is produced by batteries. Electrons move in both directions during alternating current.
Thus, It boosts the loop's flux, which creates a voltage surrounding the loop and moves an electric current through the wire.

Answer:
C. H2O (l) --> H2O (g)
Explanation:
Hello,
In this case, we need to remember that processes absorbing energy are those that have positive heat, it means, process that obtain energy from a certain source. In such a way, processes that need energy, in terms of phase chance are fusion, sublimation and evaporation, which are the change from solid to liquid, solid to gas and liquid to gas respectively. Therefore, for the given options, we can see that C. H2O (l) --> H2O (g) accounts for an evaporation process which actually absorbs energy.
Best regards.
