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 standard model? What can it explain?
Arturiano [62]

Answer:

The Standard Model of particle physics is the theory describing three of the four known fundamental forces (the electromagnetic, weak, and strong interactions, and not including the gravitational force) in the universe, as well as classifying all known elementary particles. It was developed in stages throughout the latter half of the 20th century, through the work of many scientists around the world, with the current formulation being finalized in the mid-1970s upon experimental confirmation of the existence of quarks.

When 50 ml of 1.5 M HCl is added to 100 ml of 1.5 M sodium hydroxide solution, temperature
Georgia [21]

Answer:

Q = -1.318 KJ

Explanation:

We will use the assumption that this solution acts like water and thus we will use the specific heat capacity of water and when converting from mL to g, we will use the conversion like we do for water.

We are told that 50 mL of HCl reacts with 100 mL of NaOH.

Thus total mass; m = 50 + 100 = 150 mL

Converting to grams gives 150 g since we have assumed that the solution behaves like water.

We are given;

Initial temperature; T_i = 21.3° C

Final temperature; T_f = 23.4° C

ΔT = 23.4 - 21.3

ΔT = 2.1°C

Formula for quantity of heat is;

Q = mcΔT

c is specific heat capacity.

We will use c = 4.184 J/g°C since the solution is assumed to behave like water.

Thus;

Q = -(150 × 2.1 × 4.184)

Q = -1317.96 J

Negative sign is used because temperature was raised and thus reaction is exothermic.

Approximation to KJ gives; -1.318 KJ
