Answer:

Malleability

Explanation:

Malleability is the capability of a substance, especially a metal, to be reshaped or molded into a different shape. For people in the field of chemistry, the malleability of a metal provides an important means of describing the specific features of a metal and relating it to the arrangement of the atoms within the metal.

Malleability in metals happens due to the metallic bonds that keep the atoms in place. Metallic bonds, is made up of  a 'sea' of electrons that easily move from atom to another, allow the metal atoms to slide past each other if a force is applied. The force can come from a blow from a hammer, the impact from a fall, high pressure from being squeezed, or from a collision.

The degree of malleability differs widely among metals as well as mixtures of different metals, also known as alloys. Multiple factors can affect the malleability of a metal or alloy, but two fundamentally important factors are the strength of the metallic bond and the temperature.

What is the name of this compound XeF4?
seraphim [82]
Chemical nomenclature, replete as it is withcompounds with complex names, is arepository for some very peculiar and sometimes startling names. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the consequence of simple juxtaposition. Some names derive legitimately from their chemical makeup, from the geographic region where they may be found, the plant or animal species from which they are isolated or the name of the discoverer.

Write two balanced equations
yanalaym [24]

Answer:

1. NaOH + H₂O → Na⁺ + OH⁻ + H₂O + heat

2. NaOH + HCl → NaCl + H₂O

Explanation:

1. The dissolving of NaOH in water is an exothermic reaction resulting a heat. It also causes the dissociation of NaOH to its ions (Na⁺ and OH⁻).

So, the balanced equation will be NaOH + H₂O → Na⁺ + OH⁻ + H₂O + heat.

2. The reaction between acid and base resulting salt and water. It is considered as a neutralization reaction.

The reaction between HCl and NaOH will give sodium chloride and water and the balanced equation will be NaOH + HCl → NaCl + H₂O.

atch the following aqueous solutions with the appropriate letter from the column on the right. fill in the blank 1 A 1. 0.20 m N
Firdavs [7]

Answer:

Highest boiling point - 0.43 m Urea

Second highest boiling point - 0.20 m NiSO4

Third highest boiling point - 0.19 m NH4I

Lowest boiling point - 0.17 m NH4NO3

Explanation:

We know that;

ΔT = kb m i

Where;

ΔT = boiling point elevation

kb = boiling point constant

m = molality of the solution

i = Van't Hoff factor

For NiSO4 , NH4I  and NH4NO3 , the Van't Hoff factor, i = 2

But for Urea, the Van't Hoff factor, i = 1

We also have to consider both the values of the molality and Van't Hoff factor , knowing that a higher molality and a higher Van't Hoff factor leads to a higher ΔT and consequently a higher boiling point.

This facts above account for the arrangement of substances shown in the answer.
