Answer:
The halogens are extremely reactive, whilst the noble gases are mainly inert.
Only some noble gases tend to form compounds, such as xenon and krypton. However, some like helium, almost have no compounds at all.
Noble gases also have octet rule shells, which causes the little reactivity associated with them.
To form bonds with noble gases, a lot of energy is required to form those bonds.
Halogens, on the other hand, are extremely reactive. Compounds like chlorine and fluorine must be stored carefully, as they will oxidise anything that they can find, just to get one extra electron to get an octet configuration.

Answer:
Salt. Sugar.
Explanation:
When you combine both salt, sugar and water you have a new solution, Salt water, Sugar water.
String won't change anything about the water, and sand.

Hope that helps!
Explanation:
Mutualism. They work together and both gain.
From the given balanced chemical equation,
CO2 + 2LiOH --> Li2CO3 + H2O
we can conclude that for every 2 moles of LiOH, we need a mole of CO2. Calculate first the number of moles of CO2 by dividing the given mass by the molar mass giving us an answer of 0.58 moles. Using proportionality,
0.58 / x = 1 / 2
The value of x is equal to 1.16 moles.
Answer:
False
Explanation:
The relationship between energy and amplitude can be written as eαa^2
This means that the energy of a wave is directly proportional to the square of the amplitude.
