If you’re referring to he red stuff- the liquids can be ethanol, toluene, kerosene, or isoamyl acetate. They’re transparent so they’re made more visible with red dye. (So I’d guess the answer is ethanol)
I found this in the Wikipedia article ‘Alcohol thermometer’
Answer:
If an atom, ion, or molecule is at the lowest possible energy level, it and its electrons are said to be in the ground state. If it is at a higher energy level, it is said to be excited, or any electrons that have higher energy than the ground state are excited

Answer:
2 KL + Pb(NO3)2 = 2 KNO3 + PbL2
Explanation:
KL + Pb(NO3)2 = KNO3 + PbL2 is unballanced equation, just balance from there :)
Methane was unusually high is the correct option. Hence, option B is correct.
<h3>What is methane?</h3>
Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent greenhouse gases. Its chemical formula is 
.
As the ice compacts over some time, tiny bubbles of the atmosphere or surroundings including greenhouse gases like carbon dioxide and methane—press inside the ice. These air pocket “fossils” give samples of what the atmosphere was kind when that layer of ice formed.
Based upon past studies and insights from current GHG levels, we assume that atmospheric levels of carbon dioxide and methane were unusually low.

Answer:
5.88 x 10⁻⁴Hz
Explanation:
Given parameters:
Wavelength = 510 x 10⁹m
Unknown:
Frequency = ?
Solution:
To solve this expression, we use the equation below:
V = f∧
V is the velocity = 3 x 10⁸m/s
f is the frequency
∧ is the wavelength
3 x 10⁸ = f x 510 x 10⁹
f = 5.88 x 10⁻⁴Hz
