Bonding gels and gel primers are designed specifically to improve adhesion of light cured gels to the natural nail plate and is therefore denoted as option C.
What is Adhesion?This is defined as the tendency of particles or substance which have dissimilar origins to stick to one another. A common adhesive is referred to as glue, cement etc and ensures there is enough resistance for their separation in case of the presence of any type of external force or stimuli acting on them.
Gel primer is referred to a vital used in makeup and serves as a form of foundation before they are applied on the skin of individuals so as to enable it stick and also look more presentable.
This is therefore the reason why gel primers was chosen as the most appropriate choice.

A 15.0 g piece of graphite is heated to 100.0°C and placed in a calorimeter. The
graphite releases 815.1 J of heat to reach a final temperature of 23.9°C. What is
the specific heat of graphite?
Answer:
0.714Jg^-10C^-1.
Explanation:
According to specific heat capacity, the specific heat of graphite is -0.714 J/g°C.
What is specific heat capacity?Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.
It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.
It is given by the formula ,
Q=mcΔT
In the given example, it is calculated as, c=Q/mΔT
Substituting values in above equation, c= 815.1/15×(-76.1)
c=-0.714 J/g°C
Thus, the specific heat of graphite is -0.714 J/g°C.

What is electromagnetic spectrum?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

How many peaks are there in the 13C NMR spectrum of 1,4-dimethylbenzene?
A: 8
B: 4
C: 3
D: 2
Answer:
there are four peaks in the 13c NMR (B)
To solve this we must be knowing each and every concept related to NMR. Therefore, the correct option is option B among all the given options.
What is NMR?NMR spectroscopy is a form of spectroscopy that may be used to evaluate the quality or purity of such a sample as well as the molecular weight of a substance.
It really is based on the observation that now the nuclei among most atoms have spin and that all nucleus are electrically charged. NMR spectroscopy relies on the electromagnetic radiation absorption in the radiofrequency range 3kHz-300 GHz. There are four peaks in the 13C NMR spectrum of 1,4-dimethylbenzene.
It occurs at such a wavelength that corresponds to radio frequencies, and when an electron recovers from such an excited state back ground state, it produces the same frequency radio wave.
Therefore, the correct option is option B.

Predict the approximate molecular geometry of a formaldehyde molecule:
Answer:
trigonal planar geometry
Explanation:
The molecule, formaldehyde , has three regions of electron density around the molecule. The carbon atom is the central atom in the molecule of formaldehyde.
Recall that each bond around the central carbon atom in formaldehyde- both single and double are counted as a single region of electron density. Molecules having three regions of electron density around the central atom have a trigonal planar geometry.

Explain how you can convert from the number of representative particles of a substance to moles of that substance.
Answer:
the number of representative contain in 1 mol of a substance equals to 6.o2x10^23 particles.Number of representative particles of a substance can be converted to moles of that substance by multiplying it by Avogadro's number as 1 mole=6.023 ×10²³.
What is Avogadro's number?Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.
It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .
According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Can anyone tell me 5 reactions of metals with nonmetals?
non-Metals:
Nitrogen.
Oxygen.
Helium.
Sulfur.
Chlorine.
Explanation/Answer:
Metal atoms have only a few electrons in their outer shell whereas non-metal atoms have lots of electrons in their outer shell. This means that metals tend to react with non-metals. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal.
