Answer:

\boxed{\sf c. \ ionic}

Explanation:

NH₄Cl is formed by an ionic bond between NH₄⁺ and Cl⁻ ions.

NH₄Cl (solid) ⇒ NH4⁺ (aqueous) + Cl⁻ (aqueous)

Answer:

ionic

Explanation:

In NH4Cl molecule, ionic bond is formed between NH4+ and Cl– ions, 3 covalent bonds are formed between N and three H atoms and one coordinate bond is formed between N and 1 H atom.

Carbon has four valence electrons, and oxygen has six valence electrons. If carbon and oxygen bond covalently, which of the foll
IRISSAK [1]
According to data the structures are as drawn below. 
Lewis structure is drawn by adding valence electrons of all elements present in a given compound.
In this case,
6 + 6 + 4 = 16 valence electron
secondly, the central atom is drawn in center and other outside, like carbon in center.
Then single bonds are drawn to connect the central atom to side atoms and 2 electrons for each single bonds are subtracted from total electrons, in this case 16-4=12, these 12 electrons are added to the most electronegative atoms, in this case to oxygen atoms. After that changes are made in a uch a way that each atom gets a complete octet number (8 electrons). 
So, Among these three  structures only the Blue structure is correct because in it each atom has a complete octet. While in other two oxygen or carbon has deficiency of electrons.

ZINC help asap
bazaltina [42]
Atomic # 30
Atomic mass- 65.409g
Symbol- Zn
protons = electrons,
so 30 protons,30 electrons and 35 neutrons.
The atomic mass is also found by adding the protons and neutrons.
It can be found in group 12,period 4. Zinc is a transition metal.
Zinc has an oxidation state of 2+.
Melting point- 420 C
Boiling point- 907 C
Typical compounds formed are: zinc oxide, zinc sulfide and zinc nitrate.
According to records, a German scientists named Andreas Margraf discovered the element in 1746. Even though he was recognized for the discovery, historians agree ancient people created statues with some amount of zinc.
Zinc can be found in united states, Canada and Australia.

Hope this helps!

If the half-life of a radioactive material is 8 years, how many years will it take for one-half of the original amount of materi
AlekseyPX

It will take 8 years to decay one half of the original amount of the material.

Explanation:

Radioactive materials are those which emit radiations on decaying. So the decay of radioactive materials obey a exponential order.

N = N_{0}e^{-kt}

Here, N is the number of radioactive materials present in time t, N₀ is the amount of radioactive material present at original state or at starting. Also k is termed as the disintegration constant and t is the time taken for decay.

So, disintegration constant is the rate at which the radioactive material will decay. In order to determine the time required to decay half of the original amount of radioactive materials, then we have to perform ratio of ln 2 to disintegration constant. This formula is defined as the half life time of the radioactive materials.

Thus, it can be stated as the time required to decay one half of the original amount of any radioactive material is defined as half life time of that material.

Since, here the radioactive material is said to have a half life time of 8 years, then it will require 8 years to decay one half of the original amount of the material.
