Answer:

a) barium chloride

b) iron (III) oxide

c) cesium nitrite

d) magnesium bicarbonate

Explanation:

Inorganic compounds are named based on the following conventions:

Metal cation + Non-metal anion

The name of the metal is retained as such, whereas the anion name is followed by the suffix 'ide'

For polyatomic anions the corresponding name is added to the name of the metal

Only for transition metals, the specific oxidation state exhibited by the metal cation is mentioned in roman numerals.

a) BaCl2

Ba, Barium cation +  chloride anion

Name = Barium chloride

b) Fe2O3

Fe is a transition metal. In this compound the oxidation state of Fe is +3 and not +2. Hence the name is iron (III) oxide

c) CsNO2

Cs, cesium cation + NO2-, nitrite anion

Name = cesium nitrite

d) Mg(HCO3)2

Mg, magnesium cation + HCO3-, bicarbonate anion

Name = magnesium bicarbonate

The radii of the lithium and magnesium ions are 76 pm and 72 pm, respectively. which compound has stronger ionic attraction, lit
quester [9]
 <span>From the Born–Landé equation the lattice energy U ∝ (Z+ × Z-) / (r+ + r-) where Z+ and Z- are the charges on the cation and anion, respectively; r+ and r- are radii of the cation and anion, respectively.

The Z+×Z- term dominates. MgO has 2×2 (4) so it will have the higher U than Li2O Z+ × Z- = 2.
You only consider (r+ + r-) term when the Z+×Z- term is the same; smallest the (r+ + r-),  the larger is the U. 
U(MgO) = 3795 </span>kJ mol^-1
<span>U(Li2O) = 2799 kJ mol^-1 

MgO has larger.

Calculate the grams of so2 gas present at stp in a 5.9 l container.
nata0808 [166]

<u>Answer:</u> The mass of sulfur dioxide gas at STP for given amount is 16.8 g

<u>Explanation:</u>

At STP conditions:

22.4 L of volume is occupied by 1 mole of a gas.

So, 5.9 L of volume will be occupied by = \frac{1mol}{22.4L}\times 5.9L=0.263mol

Now, to calculate the mass of a substance, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Moles of sulfur dioxide gas = 0.263 mol

Molar mass of sulfur dioxide gas = 64 g/mol

Putting values in above equation, we get:

0.263mol=\frac{\text{Mass of sulfur dioxide gas}}{64g/mol}\\\\\text{Mass of sulfur dioxide gas}=(0.263mol\times 64g/mol)=16.8g

Hence, the mass of sulfur dioxide gas at STP for given amount is 16.8 g

Part iii. Is the dissolution reaction of ammonium nitrate enthalpy favored?
lesya [120]

Answer:

No, it is not enthalpy favored since the chemical system gains energy.

Explanation:

The dissolution of ammonium nitrate in water is an endothermic process.

Endothermic process requires the system to gain energy to can dissolve the particles in water.

So, the reaction is not enthalpy favored.
