Answer:
Double Displacement (Metathesis)
Explanation:
Double Displacement (Metathesis) is like a baking soda and vinegar rocket. Only it doesn't explode and make a mess everywhere
If you stop taking them, you will get some symptoms like dizziness, vomiting, some headaches, and maybe nightmares?
Answer:
The amount of air (in grams) is required for an answer. The process is outlined below.
Explanation:
An example for 1 kg of air:
Energy = (specific heat)*(mass)*(temperature change)
Joules = (1.03J/g°C)*(1,000g)*(27°C - 9°C)
Joules = 18540J
Coversion: 1 Joule = 2.78E-07 kwh
Kwh to heat 1 kg of air from 9 to 27°C is 5.15E-03 kwh
Use the same process with the actual mass of air in the house. If you are given house dimensions, calculate the volume and multiply by the density of air to get grams air. (Remember to subtract the volume taken up by household items (e.g., beer cans).
Hydrogen is the element with atomic number one. The representation of the hydrogen molecule with a double bond is incorrect.
<h3>What is a double bond?</h3>
A double bond is a type of chemical bond that involves two pairs or four bonding electrons of the atom in a molecule. They are stronger and shorter bonds compared to single bonds.
A hydrogen molecule can never have a double bond in its molecule as it has only a single electron in its shell and cannot form a double bond due to the lack of four electrons.
Therefore, hydrogen molecules cannot form a double bond.

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.
