Why do metallic elements bend, while solid and non-metallic elements break or crumble?

Chemistry
1 answer:
Ganezh [65]3 years ago

<span>metallic elements are malleable because of its ability for the atoms to roll on top of one another without breaking its metallic bond (This is because it is attracted with more force, and is the reason why they have higher melting/boiling points); however, a nonmetals form molecular bonds which doesn't have this property</span>

What purpose does ammonia lauryl sulfate serve as a surfactor
Alborosie

Answer:

See below  

Step-by-step explanation:

Ammonium lauryl sulfate has the structural formula CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂OSO₂O⁻ NH₄⁺.

The long nonpolar hydrocarbon chain and the ionic sulfate end group make it a surfactant.  

The ionic end tends to dissolve in water, but the nonpolar chain does not. This makes the compound an excellent <em>foaming agent,</em> so it is used in many shampoos and toothpastes.

The molecules form <em>micelles</em> in water, small spherical shapes with the polar heads outside, facing the water, and the nonpolar tails are inside.

They reduce the surface tension or the water so that, when you brush your teeth or shampoo your hair, the air bubbles are stable and do not break.

What is Haber's process? Write it with chemical reaction.​
Lana71 [14]

Answer: Habers process is the industrial process used for the production of ammonia

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)

Explanation:

Habers process is the industrial process used for the production of ammonia. It uses hydrogen from natural gas and nitrogen mainly from atmosphere under extremely high pressures (150-200atm) and moderately high temperatures (400-450^0C).

The catalyst used in Habers process is iron.

The balanced chemical reaction is:

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)
