The correct answer for the question that is being presented above is this one: "<span>16.728 g."</span>
Given that
ΔHsolid = -5.66 kJ/mol.
This means that 5.66 kJ of heat is released when 1 mole of NH3 solidifies
When 5.57 kJ of heat is released
amount of NH3 solidifies = 5.57/5.66 = 0.984 moles
<span>molar mass of NH3 = 17 g/mole </span>
<span>1 mole of NH3 = 17 g </span>
So, 0.984 moles of NH3 = 17 X 0.984 = 16.728 g
So the equation is balanced, meaning they have the smallest amounts of each element in the reactants to create the products.
So, 2 moles of H2S (the coefficient) contributes to 2 moles Ag2S, which is why the ratio is 2:2.
I hope that made sense.
Answer:
1)NH4ClO4: acidic
2)NH4CN: basic
3)LiF: basic
4)KCN: basic
5)LiNO3: neutral
6)NH4Br: acidic
7)SrBr2: neutral
Explanation:
Salt is an ionic compound formed by the neutralization reaction between an acid and a base.The cation of base and anion from an acid combines to form a salt while H+ from acid and OH- from base forms water.
1)NH4Cl4: is an acidic salt formed from neutralization reaction between strong acid and a weak base.
2)NH4CN: is a basic salt formed from neutralization reaction between weak acid and weak base.
3)LiF: basic salt formed from neutralization reaction between strong acid and strong base.
4)KCN: basic salt formed from neutralization reaction between weak acid and strong base.
5)LiNO3: neutral salt formed from neutralization reaction between strong acid and strong base.
6)NH4Br: acidic salt formed from neutralization reaction between strong acid and weak base.
7)SrBr2: neutral acid formed from neutralization reaction between
strong acid and strong base.
