2. 2Al(s) + 6HCl(aq) + 2AlCl3(aq) + 3H2(g) represents a single replacement reaction
<h3>Further explanation</h3>
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Not all of these reactions can occur. We can use the activity series(voltaic series), which is a list of elements that can replace other elements below / to the right of them in a single replacement reaction.
1. 2Al(s) + 3Cl2(g) → 2AlCl3(s)
Syntesis/combination reaction
2. 2Al(s) + 6HCl(aq) ⇒2AlCl3(aq) + 3H2(g)
Single replacement reaction
3. 2AlCl3(s) → 2Al(s) + Cl2(g)
Decomposition reaction
4. AlCl3(aq) + 3KOH(aq) + Al(OH)3(s) + 3KCl(aq)
Double replacement reaction
1.) ionic bond
2.)ions
3.) the number of protons stay the same. (Wasn’t sure what it was asking. )
4.)an atom is neutral because it has the same amount of protons and neutrons
5.)because ions either have more positive protons or more negative electrons making the ion either positive or negative
The reaction is combination of hydrogen molecules and oxygen molecules and form water. So the oxygen and hydrogen required together is equal to the mass of the water formed.
I found the grams per mole values based off of the atomic mass of iodine and Magnesium
