The product that is used on the natural nail prior to application to assist in adhesion and serves to chemically bond the enhancement product to the natural nail is known as nail primer.
<h3>What is a nail primer?</h3>
A nail primer is a chemical agent used in esthetic centers before applying a colored polish to the nails and serves as an adhesive product.
The nail primers are also very useful for improving the cleaning efficiency of the product before its application.
Nail care products include different types of chemical formulations such as, for example, creams that reinvigorate the cuticle.
In conclusion, the chemical formulation employed on the natural nail that is capable of enhancing and also assisting adhesion is called the nail primer.

Answer:
Explanation:
Initial burette reading = 1.81 mL
final burette reading = 39.7 mL
volume of NaOH used = 39.7 - 1.81 = 37.89 mL .
37.89 mL of .1029 M NaOH is used to neutralise triprotic acid
No of moles contained by 37.89 mL of .1029 M NaOH
= .03789 x .1029 moles
= 3.89 x 10⁻³ moles
Since acid is triprotic , its equivalent weight = molecular weight / 3
No of moles of triprotic acid = 3.89 x 10⁻³ / 3
= 1.30 x 10⁻³ moles .
The general gas law equation that is formed by combining the three laws of Boyle, Charle and Guy Lussac is written as:
(PV/T)1 = (PV/T)2
STP conditions means that T= 273 kelvin and P = 1 atmospheric pressure
Based on the above rule, we calculate V2 as follows:
(4.25*55)/500 = (1*V)/273
V2 = 127.599 liters
Extra notes:
Boyles law: volume and pressure of a certain mass of gas are inversely proportional provided that the temperature is constant
Charle's law: volume and temperature of a certain mass of gas are directly proportional provided that the pressure is constant
Guy Lussac's law: pressure and temperature of a certain mass of gas are directly proportional provided that the volume is constant
Answer:
• 1 kilocaloric equals 1000 gram calories
• 1 kilocalorie is equals to 4184 Joules of energy.
Explanation:
One kilocalorie is equals to 1000 gram calories because one kilo is equals to or have 1000 grams. One kilocalorie is equals to 4184 Joules of energy while on the other hand, one calorie is equals to 4.184 Joules of energy because one calorie is 1000 times smaller than Kilocalorie so calorie has also 1000 times lower energy than kilocalorie. Kilo is the prefix which means 1000 so we can say that One kilocalorie is equals to 1000 gram calories.
I believe it is A because a physical change is something that can be changed back to where a chemical change can not be such as burning something.
