Compressions are regions of high pressure due to particles being close together
rarefactions are regions of low pressure due to particles being spread further apart
Longitudinal waves are often demonstrated by pushing and pulling a stretched slinky spring
Answer:
<em>The </em><em>correct </em><em>formula </em><em>for </em><em>Aluminium </em><em>Cyanide </em><em>is </em><em>Al(</em><em>CN)</em><em>3</em>
Explanation:
<h3>Structure of AlCN3</h3>

Al(CN)3 is an ion consisting of one Al3+ ion and 3 (CN)- ions held by electrostatic force of attraction!!</h3>
B,Si,Ge,As,Sb,Te, and At are all the metalloids on the periodic table of elements.
Using the mole ratio and stoichiomrtery, you get:
65.9 g FeO x (molar mass of FeO) x (3 mol Fe/ 3 mol FeO) x (molar mass of Fe).
Plug in the values and you’re good to go!
Only 2nd reaction is a single replacement reaction
<h3>What is a single replacement reaction?</h3>
A single replacement reaction is a reaction in which an element is replaced by another element in a compound.
It is often called a single displacement reaction
The reactants in this reaction are always pure elements and an aqueous compound.
When this reaction occurs, a new aqueous compound and other pure elements are formed as products.
We can write a general single replacement reaction as:

Hence, only 2nd reaction is a single replacement reaction that is
