a. Hydrogen
Hydrogen has a line at 410 nm.
Mercury has a line at 405 nm.
Sodium and neon have no lines near 412 nm.
Answer:
1. sublimation
2.melting
3.melting
4.sublimation
Explanation:
melting is a process when solid changes to liquid
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.
1) color change - for example, when bleach is shot down by mistake, in colored clothing;
2) gas release - for example, when playing an effervescent tablet in water.
3) heat release - for example in combustion;

The two chemical formulas which will correctly complete the table for lithium fluoride are: A. HF, LiOH.
<h3>What is a chemical reaction?</h3>
A chemical reaction can be defined as a chemical process that involves the continuous transformation (rearrangement) of the ionic, atomic or molecular structure of a chemical element by breaking down and forming chemical bonds, in order to produce a new chemical compound while new bonds are formed.
This ultimately implies that, chemical bonds between atoms of a chemical element are broken and then new bonds are formed in all chemical reactions.
<h3>What is a neutralization reaction?</h3>
A neutralization reaction can be defined as a type of chemical reaction between an acid and a base, which typically leads to the formation of an ionic compound (salt) and water as end products as shown below:
LiOH(aq) + HF(aq) → LiF(s) + H₂O(l)
In this context, we can infer and logically deduce that the two chemical formulas which will correctly complete the table for lithium fluoride are HF and LiOH.
