Answer : The number of ions produced in the dissociation of the compound BaS are, two.

Explanation :

Dissociation reaction : It is defined as the chemical reaction in which a compound breaks into two or more ions.

The general representation of reaction is :

AB\rightarrow A+B

The dissociation reaction of the given compound will be,

BaS\rightarrow Ba^{2+}+S^{2-}

From the reaction we conclude that, there are two ion are produced in the dissociation of BaS compound which are, Ba^{2+} ion and S^{2-} ion.

Hence, the number of ions produced in the dissociation of the compound BaS are, two.

for the reaction 2Fe + O2 = 2FeO, how many grams of iron oxide are produced from 8.00 mol of iron? when o2 is an excess
Luba_88 [7]

Answer:

2Fe + O₂ -------------------> 2FeO

8 mol Fe produce

8 mol Fe * 2 mol FeO / 2 mol Fe = 8 mol FeO

Mass of FeO = 8 mol FeO * 71.85 g/mol = 574.8 grams FeO

Explanation:

Having 8 mol of Iron means 8 moles of iron oxide can be produced. Each mole of iron oxide has a molecular weight of 71.85 grams. Therefore, 8 moles of iron oxide should weight 574.8 grams.

The solubility of sodium hydrogen carbonate in water 20 degrees is 9.6 g/100 g h2o.
d1i1m1o1n [39]

We can see from the details below that, the value of the solution's molality is 1.14 mol/Kg.

<h3>What is solubility?</h3>

The term solubility has to do with the quantity of solute that is able to dissolve in a given quantity of solvent. We have the solubility of the sodium hydrogen carbonate in water at 20 degrees as 9.6 g/100 g h2o.

Number of moles of sodium hydrogen carbonate = 9.6 g/84 g/mol = 0.114 moles

Number of moles water = 100 g /18 g/mol = 5.55 moles

Mole fraction of sodium hydrogen carbonate is obtainable by the use of the relation;

0.114 moles/0.114 moles + 5.55 moles

= 0.02

Molality of the solution = 0.114 moles/0.1 Kg = 1.14 mol/Kg
