Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter, causing the metal to stiffen and fracture. This is known as metal fatige. The bending causes that to occur.
What is metal ?A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Generally speaking, metals are malleable and ductile.
These characteristics are the outcome of the metallic link that exists between the metal's atoms or molecules.
The earth's crust is where most pure metals are found. They are discovered in ores, which are solid materials from which metals and minerals may be extracted. The majority of the planet's iron mass, which makes up over a third of its mass, is located in its core.
Thus, Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter.

What is the total amount of heat needed to change 2.25 kg of silver at 0.0°C to 200.0°C? The specific heat of silver is 0.129 J/g·°C (2.25 kg = 2250 g)
Answers
Answer:
Q = 5805 Joules.
Explanation:
Given the following data;
Mass = 2250g
Specific heat capacity of silver = 0.129 J/g·°C
Initial temperature, T1 = 0.0°C
Final temperature, T2 = 200.0°C
To find the quantity of heat needed;
Heat capacity is given by the formula;
[tex] Q = mcdt[/tex]
Where;
Q represents the heat capacity or quantity of heat. m represents the mass of an object. c represents the specific heat capacity of water. dt represents the change in temperature.dt = T2 - T1
dt = 200 - 0
dt = 200°C
Substituting the values into the equation, we have;
[tex] Q = 225*0.129*200[/tex]
Q = 5805 Joules.
Therefore, the amount of heat needed is 5805 Joules.
Given values:
Mass, [tex]m = 2250 \ g[/tex]Specific heat capacity, [tex]0.129 \ J/g.^{\circ} C[/tex]Initial temperature, [tex]T_1 = 0.0^{\circ} C[/tex]Final temperature, [tex]T_2 = 200.0^{\circ} C[/tex]then,Change in temperature, [tex]dt = T_2-T_1[/tex][tex]= 200-0[/tex]
[tex]= 200^{\circ} C[/tex]
As we know the formula,
→ Heat capacity, [tex]Q = mcdt[/tex]
By substituting the values, we get
[tex]= 225\times 0.129\times 200[/tex]
[tex]= 5805 \ Joule s[/tex]
Thus the above answer is right.

Answers
Answer:
the mass of 8.03 mole of NH3 is 136.51 g
Explanation:
The computation of the mass is shown below:
As we know that
Mass = number of moles × molar mass
= 8.03 mol × 17 g/mol
= 136.51 g
Hence, the mass of 8.03 mole of NH3 is 136.51 g
We simply multiplied the number of moles with the molar mass so that the mass could come

The answers are in the picture. this us the question, An increase in carbon dioxide production has led to an increase in global temperatures, which is causing glaciers to melt faster. If this trend continues, how will animals living in the polar regions be affected?
Answers
Answer:
D
Explanation:
because if there is no land for them they wont survive in only water
The increase in global temperature melts the ice in polar regions. This worsely affects the animals living there. Hence, they will migrate to other areas but this is in fact not possible for their adaptation in other areas and they may subject to extinction.
What is global warming ?Global warming is the rise of temperature of earth surface all over the world. The significant reason for global warming is green house effect. Gases like carbon dioxide, methane gas etc. are intensely absorbing temperature that is radiating back from earth.
Hence, these gases are increasing the atmospheric temperature in earth. Global warming have very serious impacts that going up to the major discussion to solve nowadays.
The melting of polar icebergs and rising of sea level definitely leads to the extinction of animals living in polar region. They cant be adopted to other regions and migrating to other areas does not save them. Hence, they will extinct from earth. Therefore, option d is correct.

Answers
Answer:
c. F
Explanation:
As you go top to bottom down a column of the periodic table, atomic radius increases.
As you go left to right across a period of the periodic table, atomic radius decreases.
Knowing this trend, that means that the smallest atomic radius would be located in the top right of the periodic table. The closest element to that point is fluorine, or answer C.

Neon is used in lighting advertising displays.
Which statement can be applied to an atom of neon?
A The atom has the same electron arrangement as Cl– ion.
B The atom has two more electrons than an atom of oxygen.
C The atom has the same number of outer electrons as an atom of helium.
D The atom has the same number of electrons as a Ca2+ ion.
Answers
Answer:
B. The atom has two more electrons than an atom of oxygen.
Explanation:
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Oxygen has a total number of eight (8) electrons while neon has total number of ten (10) electrons. Therefore, an atom of oxygen is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon with an atomic number of 10.
This ultimately implies that, an [tex] O^{2-} [/tex] atom contains the same number of electrons as an atom of neon.
Hence, a neon atom has two more electrons than an atom of oxygen.
Additionally, Neon is used in lighting advertising displays.
______ meters = 177 millimeters
Answers
Answer:
117 millimeters = 0.117 meters
Explanation:
This is using unit conversions. There are 1000 millimeters in 1 meter, so you would divide your starting value, 117 millimeters by 1000 millimeters. The units will cancel because they are being divided by themselves and you are left with 0.117 meters.
