The decomposition of 57.0 g of Fe2O3 results in Consider the following reaction. 2Fe2O3 ---> 4Fe + 3O2 deltaH degree rxn = +
lozanna [386]

Answer:

The correct answer is option E.

Explanation:

2Fe_2O_3\rightarrow 4Fe + 3O_2 \Delta H^o_{rxn} = 824.2 kJ

Mass of ferric oxide decomposed = 57.0 g

Moles of ferric oxide decomposed = \frac{57.0 g}{160 g/mol}=0.35625 mol

According to reaction, 2 moles ferric oxide on combustion gives 824.2 kJ of heat.

Then heat given by on decomposition of 0.35625 mol of ferric oxide will be:

\frac{824.2 kJ}{2}\times 0.35625 =146.81 kJ\approx 147 kJ

So, on decomposition of 57.0 grams of ferric oxide 147 kilo Joules of heat was released.

Which of the following compounds are held together by ionic bonds? Water, salt, sugar, carbon dioxide
Vika [28.1K]

Answer:

Salt.

Explanation:

Salt=NaCl

Ionic bonds are made when the two elements are from different sides of the periodic table. On the left, we have our metals. On the right, we have our nonmetals. Sodium is a metal and Chlorine is a gas. Water, sugar, and carbon dioxide are covalent bonds because all the elements are from the right side of the periodic table. Hydrogen is a nonmetal too.

Compared to the boiling point and the freezing point of water at 1 atmosphere, a 1.0 M CaCl2(aq) solution at 1 atmosphere has a
Vlada [557]

Answer:

Higher boiling point and lower freezing point

Explanation:

Boiling point is the temperature at which substances goes to gaseous phase form their liquid phase. Liquids boil when vapour pressure of the liquid becomes equal to atmospheric pressure. So boiling point of a liquid is affected by the change in its vapour pressure and vapour pressure is affected by adding a non-volatile solute in it.

Effect of adding non -volatile solute on vapour pressure:

When a non-volatile solute is added to a liquid, it alters the interaction between the liquid particles and prevents the liquid particles to going into gaseous phase which results in decrease in vapour pressure. More energy is needed for the vapour pressure of the liquid to becomes equal to atmospheric pressure. Therefore, boiling point increases.

CaCl2 is a non-volatile solute and hence increases the boiling point of the water.

Effect of adding non-volatile solute on freezing point:

When a non-volatile solute is added to a liquid, it alters the interaction between the liquid molecules. The new solute and solvent interaction prevents the liquid to soldify and requires more lowering in temperature. Therefore, freezing point decreases.

Rashid [163]

Answer:

2.94 grams Nickle

Explanation:

All they are asking is to convert moles to grams

To do this, find the atomic mass of nickel using the periodic table: 58.693 g

0.05 mol * 58.693 g/1 mol = 2.93465 grams
