NaCl(aq) AgNO3(aq) → AgCl(s) NaNO3(aq) : NaCl(aq) AgNO3(aq) \rightarrow AgCl(s) NaNO3(aq) : blank H2SO4(aq) 2 LiOH(aq) → 2 H2O(l

The question is incomplete, here is a complete question.

Categorize each reaction into types of chemical reactions.

(1) $NaCl(aq)+AgNO_3(aq)\rightarrow AgCl(s)+NaNO_3(aq)$

(2) $H_2SO_4(aq)+2LiOH(aq)\rightarrow 2H_2O(l)+Li_2SO_4(aq)$

(3) $HCl(aq)+(NH_4)_2S(aq)\rightarrow H_2S(g)+2NH_4Cl(aq)$

(4) $Mg(s)+Cu(NO_3)_2(aq)\rightarrow Mg(NO_3)_2(aq)+Cu(s)$

Answer :

(1) Precipitation reaction

(2) Neutralization reaction

(3) Double-displacement reaction

(4) Single replacement reaction

Explanation :

(1) The balanced chemical reaction is:

$NaCl(aq)+AgNO_3(aq)\rightarrow AgCl(s)+NaNO_3(aq)$

This reaction is a precipitation reaction in which an insoluble salt formed when two aqueous solutions are combined. The insoluble salt that settle down in the solution is known an precipitate.

(2) The balanced chemical reaction is:

$H_2SO_4(aq)+2LiOH(aq)\rightarrow 2H_2O(l)+Li_2SO_4(aq)$

This is a neutralization reaction in which an acid react with a base react to give salt and water as a product that means it reacts to give a neutral solution.

(3) The balanced chemical reaction is:

$HCl(aq)+(NH_4)_2S(aq)\rightarrow H_2S(g)+2NH_4Cl(aq)$

The given reaction is a double-displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.

(4) The balanced chemical reaction is:

$Mg(s)+Cu(NO_3)_2(aq)\rightarrow Mg(NO_3)_2(aq)+Cu(s)$

This reaction is a single replacement reaction in which the the more reactive element replace the less reactive element.

Which would have a greater impact on the actual mass of a particular soduim atom?

Margaret [11]

The protons contribute significantly more to an atom's mass because sodium has an atomic number of 11, where the number of protons in a neutral sodium atom is equal to the number of electrons. In the first group or column of the periodic table, sodium is an alkali metal.

The sodium atom mass has 11 protons and electrons, and its outermost shell has one valence electron. Pure sodium has a high level of reactivity. Since it is such a soft metal, a knife may be used to cut it with ease. The chemical element sodium has the atomic number 11 and the symbol Na.

Based on the reaction below:

Sidana [21]

N₂ + 3H₂ ⇄ 2NH₃ + heat

In the given equilibrium, we notice that the heat is on the right. which means that if the heat requirements don't meet, the reactants on the right will no longer react due to the lack of heat

but because the reactants on the left don't have such weaknesses, they will keep reacting hence producing more and more ammonia until a new equilibrium is reached

where there will be more ammonia and less nitrogen and hydrogen as compared to the equilibrium we had initially
