What is the mechanical properties of polymers?
The moduli of elasticity and other classes of strength measures, such as the yield and tensile strengths, can be used to characterize the mechanical properties of polymers in a manner that is quite similar to that of metals or other common crystalline materials. The most significant mechanical and elastic characteristics of polymeric materials are summarized generally below:
Strength: Whenever the applied force is greater than a straightforward linear elastic deformation, represents the stress force required to fracture the material sample under investigation. Tensile strength (stretching of the polymer), compressional strength (compressing the polymer), flexural strength (bending of the polymer), torsional strength (twisting of the polymer), and impact strength are some of the most important types of strength quantities used in typical materials characterization measurements (e.g. under the effects of direct hammering).Percent Elongation to Break (Ultimate Elongation): This statistic, expressed as a percentage change in the material's length, describes the maximum strain that the polymer sample can experience before it ultimately breaks (at the aforementioned strength point).Young's Modulus: A measure of a material's total stiffness, it is the ratio of stress to strain in the region of its linearly elastic response.To know more about Mechanical properties of polymers, visit:

A 25.0 mL aliquot of 0.0680 M EDTA was added to a 59.0 mL solution containing an unknown concentration of V3 . All of the V3 present in the solution formed a complex with EDTA , leaving an excess of EDTA in solution. This solution was back-titrated with a 0.0400 M Ga3 solution until all of the EDTA reacted, requiring 13.0 mL of the Ga3 solution. What was the original concentration of the V3 solution
Answers
Answer:
\(\mathbf{0.02 M}\)
Explanation:
\(\text{So, from the given question:}\)
\(\text{EDTA will make complex with}\) \(V^{+3}\) \(\text{and the remaining EDTA will react with }\)\(Ga^{+3}\)
\(\text{Hence, the total concentration of}\) \(V^{+3}\) & \(Ga^{+3}\) \(\text{will be equivalent to EDTA concentration.}\)
\(V_{EDTA} = 25 \ mL\)
\(V_{V^{+3}} = 59.0 \ mL\)
\(V_{Ga^{+3}} = 13.0 \ mL\)
\(M_{EDTA} = 0.0680 \ M\)
\(M_{V^{+3}} = ???(unknown)\)
\(M_{Ga^{+3}} = 0.0400 \ M\)
\(V^{+3} + EDTA \to V[EDTA] + EDTA(Excess) \to^{CoA} \ Ga[EDTA] _{complex}\)
\(M_{EDTA} \times V_{EDTA} = ( V_{V^+3}\times M_{V^{+3}}+ V_{Ga^{+3} }\times M_{Ga^{+3}}})\)
\(0.0680 \times 25 = (59\times x + 13 \times 0.040) \\ \\ 1.7 = 59x + 0.52\\ \\ 1.7 - 0.52 = 59x \\ \\ 59x = 1.18\)

What is the primary reason that atomic radius decreases as you move from left to right across the periodic table even through the number of electrons is increasing?
Answers
Answer:
As you move across a period the electrons are being added to the same shell. But, protons are being added as well. This makes the nucleus more positively charged and, increasing protons has a greater effect than electrons. So, there is a greater nuclear attraction and, because the electrons are being added to the same shell that shell gets pulled in more. This causes a decrease in atomic radius.
Explanation:
The primary reason that atomic radius decreases as you move from left to right across the periodic table is; Due to the increase in electrostatic attraction between the positively charged nucleus and the negatively charged electrons.
The number of shells in elements located in the same period are equal.
However, with successive increase in the atomic number, the number of electrons and protons increases.
Consequently, the electrostatic attraction between the positively charged nucleus and negatively charged electrons increases and the radius reduces accordingly.

Two positive aspects of using methane recapture systems are able to generate significant electricity. Another benefit is that the process of anaerobic digestion creates heat that can be used to warm buildings where animals are kept
Answer: The correct answer is;
Two positive aspects of using methane recapture systems include lowering the impact on greenhouse gasses and the production of energy. Methane is a very potent greenhouse gas that is contributing to global warming. As a result, the recapturing process reduces the methane impacts of global warming by reclaiming and reusing the gas for other purposes. Recaptured methane can be stored and used to generate electricity or used as fuel to power updated vehicles and other engines on the farm. The overall benefits from this combination are reducing impacts causing global warming and lower the cost of electricity or fuel on the farm.

If 62.1 grams of magnesium react with 100.0 grams of magnesium, how many grams of product are produced?
Which is the Limiting reactant?
Which is the Excess reactant?
How many grams of excess reactant remain?
pls help me with homework
Answers
The limiting and excess reactant can be obtained as follow:
2Mg + O₂ -> 2MgO
Molar mass of Mg = 24 g/molMass of Mg from the balanced equation = 2 × 24 = 48 g Molar mass of O₂ = 32 g/molMass of O₂ from the balanced equation = 1 × 32 = 32 gFrom the balanced equation above,
48 g of Mg reacted with 32 g of O₂
Therefore,
62.1 g of Mg will react with = (62.1 × 32) / 48 = 41.4 g of O₂
We can see from the above that only 41.4 g of O₂ is required to react completely with 62.1 g of Mg.
Thus, the limiting reactant is magnesium, Mg and the excess reactant is oxygen, O₂
How do i determine the mass of the excess reactant remaining?The mass of the excess reactant remaining can be obtained as shown below:
Mass of excess reactant, O₂ given = 100 gMass of excess reactant, O₂ that reacted = 41.4 gMass of excess reactant, O₂ remaining =?Mass of excess reactant remaining = Mass given - mass reacted
Mass of excess reactant remaining = 100 - 41.4
Mass of excess reactant remaining = 58.6 g
How do i determine the mass of product produced?The mass of H₂SO₄ produced can be obtained as illustrated below:
Mg + O₂ -> 2MgO
Molar mass of Mg = 24 g/molMass of Mg from the balanced equation = 2 × 24 = 48 g Molar mass of MgO = 40 g/molMass of MgO from the balanced equation = 2 × 40 = 80 gFrom the balanced equation above,
48 g of Mg reacted to produce 80 g of MgO
Therefore,
62.1 g of Mg will react to produce = (62.1 × 80) / 48 = 103.5 g of MgO

What will happen to the temperature, as
thermal energy is added to the ice over time?
OK
Answers
Answer:
When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted. This happens because all the heat energy goes into breaking the bonds of the ice's crystal lattice structure.
Explanation:
Shards of ice fly from the sculptor’s chisel. As the crowd
looks on, a swan slowly emerges from a massive block of ice. As
the day wears on, however, drops of water begin to fall from the
sculpture. Drip by drip, the sculpture is transformed into a puddle of liquid water. What makes matter change from one state to
another? To answer this question, you need to think about the
particles that make up matter.
Energy Simply stated, energy is the ability to do work or cause
change. The energy of motion is called kinetic energy. Particles
within matter are in constant motion. The amount of motion of
these particles depends on the kinetic energy they possess. Particles
with more kinetic energy move faster and farther apart. Particles
with less energy move more slowly and stay closer together.
The total kinetic energy of all the particles in a sample of
matter is called thermal energy. Thermal energy, an extensive
property, depends on the number of particles in a substance as
well as the amount of energy each particle has. If either the
number of particles or the amount of energy in each particle
changes, the thermal energy of the sample changes. With identically sized samples, the warmer substance has the greater thermal energy. In Figure 7, the particles of hot water from the hot
spring have more thermal energy than the particles of snow on
the surrounding ground.
