A reaction in which the chemical element of the reactant is replaced by another to produce a product is called a single replacement reaction.
In a reaction, a hydrogen, metal or halogen element can get replaced with other more reactive elements to yield products.
The reaction of magnesium and hydrochloric produces:
The reaction can be explained as:
- The reaction between the and is a single displacement reaction in which the more reactive metal replaces the less reactive metal from the compound.
- Magnesium metal is more reactive compared to hydrogen and hence replaces from chlorine to produce:
Therefore, another product formed will be magnesium chloride.

Answer:
hello your question is incomplete below is the missing part of the question
Keisha makes a table to compare plasmas and solids.
Plasma
Solid
Kinetic energy
X
Density
Y
Which labels belong in the cells marked X and Y? X: High Y: High X: High Y: Low X: Low Y: High X: Low Y: Low
answer : X: High Y:High
Explanation:
The labels that belong in the cells are ; X: High Y:High this because when comparing Plasma and Solids the variables; X and Y have positive correlation hence when X is High, Y will be High as well
