Which of the following lists elements in order of increasing malleability?

2 answers:

8 0

Malleability is the property due to which substances tend to hammered into thin sheets when pressure is applied. Malleability is observed in metal as the metal atoms are bound by metallic bonds. The layers of metal atoms can roll over each other without breaking the metal bond when pressure is applied. In the periodic table malleability decreases as the metallic nature decreases. Among the given metals Al is the most metallic element, followed by Zinc an Carbon is a non metal. Therefore, the order of increasing malleability will be C, Zn, Al

<h2>Answer:</h2>

The correct order of list of elements in order of increasing malleability is C, Zn, Al.

<h3>Explanation:</h3>

Flexibility/Malleability is a substance's capacity to distort under strain (compressive pressure). On the off chance that pliable, a material might be straightened into thin sheets by pounding or rolling. Malleable materials can be leveled into metal leaf.
This property is dominated in metals as compared to nonmetals.
As carbon is a nonmetal and zinc is a metal but rather of weak metallic properties than aluminum.
Hence malleability will increase from C to Zn to Al.

Answer:

Hornfels most commonly form in the aureole of granitic intrusions in the upper or middle crust. Hornfels formed from contact metamorphism by volcanic activity very close to the surface can produce unusual and distinctive minerals.

Be sure to answer all parts. Nitric oxide, NO·, is a radical thought to cause ozone destruction by a mechanism similar to that o

SIZIF [17.4K]

Answer:

See image attached and explanation

Explanation:

The stratospheric ozone layer is very important in absorbing high-energy ultraviolet radiation that is harmful to living systems on earth. The concentration of ozone in the stratosphere is determined by both thermal and photochemical pathways for its decomposition. Nitric oxide, NO, is a trace constituent in the stratosphere that reacts with ozone to form nitrogen dioxide, NO2, and the diatomic oxygen molecule. The nitrogen-oxygen bond in NO2 is relatively weak. When an NO2 molecule encounters an oxygen atom, it transfers an oxygen, forming O2 and NO. The chemical reactions involved are formations of NO2 following by reaction of NO2 with atomic oxygen for form NO and O2. The sum of both reactions show that the overall reaction is simply the reaction of ozone with atomic oxygen to form two molecules of molecular oxygen. Hence, NO only serves as a catalyst, it does not undergo a permanent change itself.

3.0 x 108 m/s is the

Veseljchak [2.6K]

Answer:

Speed of light

Explanation:

The value 3.0 x 10⁸m/s is taken as the speed of light.

It is a constant.

It implies that light travels a distance of 3 x 10⁸ in just one second.
This value is for the speed of light in a vacuum when there are not particles obstructing its movement.
The speed of electromagnetic radiations in free space is also taken as the speed of light.

How much energy is required to vaporize 14.27 grams of water at its<br> boiling point? *

laila [671]

Energy required to vaporize : 32.3 kJ

<h3>Further explanation </h3>

The heat to change the phase can be formulated :

Q = mLf (melting/freezing)

Q = mLv (vaporization/condensation)

Lf=latent heat of fusion

Lv=latent heat of vaporization

Mass of water = 14.27 g

Latent heat of vaporization ( boiling point of 100 ºC) : 2260 J/g

Energy required :

$\tt Q=m.Lv\\\\Q=14.27\times 2260\\\\Q=32250.2~J\approx 32.3~kJ$
