Answer:
To regulate the gas pressure in the lighter tank and avoid build-up of pressure.
Explanation:
- First, you need to understand the properties of this organic molecule. Butane. C₄H₁₀ is a colorless, odorless, but HIGHLY FLAMMABLE liquefied gas. The liquid is flammable at 25⁰C whilst the vapor is flammable at 15⁰C. As you can see, this is an extremely flammable gas. It has a high vapor pressure (tendency by liquids to escape as gas molecules)
- Any external heat source induces a pressure build up that might cause the gas to explode when there is an open flame.
- Combining the two points above, a thermo-regulated water bath that has a lower temperature (below 15⁰C) will be need to prevent the pressure build up and ensure that any leakage will not have a high vapor pressure.

Answer:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA.
EXPLANATION: SO THE CORRECT ANSWER IS
"NUCLEIC ACID"
The name of the ion is Copper.
<u>Explanation</u>:
- Copper is a chemical element symbolized as Cu. It has different ions, one of which is Cu(2+) and Cu(1+).
- Copper on losing 2 electrons forms the ion Cu(2+)
- Copper(2+) is an ion that carries double positive charge.
- It plays the role of a cofactor.
- It is also more stable than the single positive ion Cu(1+)
1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it
2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth
3) mass and how far away you are from the object
4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)
5) when distance increases, gravity decreases (again I do not remeber by how much)
