Metallic bonds

Explanation:

The physical properties of metals such as malleability, ductility, electrical and thermal conductivity, luster e.t.c is controlled by metallic bonds.

  • Metallic bonds join atoms of metals and alloys together.
  • The formation of this bond type is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.
  • Metallic bond is actually an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud jointly formed by all atoms losing their outermost shell electrons.

An iron nail rusts when exposed to oxygen. According to the following reaction, how many grams of iron(III) oxide will be formed
natka813 [3]

Answer: 103.8 g of Fe_2O_3, 0.65 moles of

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} O_2=\frac{31.1}{32}=0.975moles

Thus O_2 is the limiting reagent as it limits the formation of product and Fe is the excess reagent.

4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3

According to stoichiometry :

3 moles of O_2 produce =  2 moles of Fe_2O_3

Thus 0.975 moles of O_2 will produce=\frac{2}{3}\times 0.975=0.65moles of Fe_2O_3

Mass of Fe_2O_3=moles\times {\text {Molar mass}}=0.65moles\times 159.69g/mol=103.8g

Thus 103.8 g of Fe_2O_3 will be produced.

Answer:

The reaction is favorable at all temperatures

Explanation:

Since G = H - TS, -H and +S would result in G = -H -TS, which will always be negative.

If 57.3 l of 0.497 m koh is required to completely neutralize 39.5 l of a CH3COOH solution. What is the molarity of the acetic a
bearhunter [10]

The molarity of the solution will be 0.72 m.

The majority of reactions take place in solutions, making it crucial to comprehend how the substance's concentration is expressed in a solution when it is present. The number of chemicals in a solution can be stated in a variety of ways, including.

The symbol for it is M, and it serves as one of the most often used concentration units. Its definition states how many moles of solute there are in a liter of solution.

Given data:

V_{1} =57.3 L\\V_{2} = 39.5 L\\M_{1} = 0.497 m\\\\M_{2} = ?

Molarity can be determined by the formula:

M_{1} V_{1} = M_{2} V_{2}

where, M is molarity and V is volume.

Put the value of given data in above equation.

57.3 × 0.497 m = M × 39.5 L

M = 0.72 m

Therefore, the molarity of the solution will be 0.72 m
