Answer:
Sugar
Explanation:
Defintion of a solute-dissolved in the solvent, sugar dissolves in water and is therefore the solute
Answer:
-176.0 kJ/mol
Explanation:
Let's consider the following balanced reaction.
NH₃(g) + HCl(g) → NH₄Cl(s)
We can calculate the standard enthalpy change for the reaction (ΔH°rxn) using the following expression.
ΔH°rxn = 1 mol × ΔH°f(NH₄Cl(s)) - 1 mol × ΔH°f(NH₃(g)) - 1 mol × ΔH°f(HCl(g))
ΔH°rxn = 1 mol × (-314.4 kJ/mol) - 1 mol × (-46.1 kJ/mol) - 1 mol × (-92.3 kJ/mol)
ΔH°rxn = -176.0 kJ/mol
The answer is that "<span>Ag+</span> ion combines with the chloride ion to form a precipitate".
Silver chloride is formed in the form of precipitates, Ag⁺ is a cation and Cl⁻ is an anion so both ions attract each other and combines to form AgCl.
The equation for the ionic reaction that occurs is;
<span><span>Ag</span></span>⁺(aq)+Cl⁻(aq)→AgCl(s)
Answer:
2K + HgCl2 —> Hg + 2KCl
Explanation:
K + HgCl2 —> Hg + KCl
The above equation is not balanced
To balance the equation, do the following.
First, put 2 in front of KCl, the equation becomes,
K + HgCl2 —> Hg + 2KCl
Now we see that Cl is balanced but K is not. To balance K, put 2 in front of K as shown below:
2K + HgCl2 —> Hg + 2KCl
Now we can that the equation is balanced
