Answer:
The maximum possible yield strength for a single crystal is 70 MPa.
Explanation:
To find the maximum possible yield strength for a single crystal we need to use the following equation:
[tex]\sigma_{y} = \frac{\tau_{CRSS}}{m_{max}}[/tex]
Where:
[tex]m_{max}[/tex] is the maximum value for Schmid factor
[tex]\tau_{CRSS}[/tex] is the critical resolved shear stress = 35 MPa
[tex] \sigma_{y}[/tex] is the yield strength =?
The Schmid factor is given by:
[tex]m = cos(\phi)cos(\lambda)[/tex]
And its maximum value is obtained when λ = 45° and Φ = 45°, so:
[tex] m = cos(45)cos(45) = 0.5 [/tex]
Finally, the maximum possible yield strength is:
[tex]\sigma_{y} = \frac{\tau_{CRSS}}{m_{max}} = \frac{35 MPa}{0.5} = 70 MPa[/tex]
Therefore, the maximum possible yield strength for a single crystal is 70 MPa.

What is the volume in liters of 222 g of neon if neon has a density of 0.900 g/L?
Answer:
[tex]V=247L[/tex]
Explanation:
Hello there!
In this case, since the density is defined as the degree of compactness of a substance and is computed by diving the mass over the volume it occupies:
[tex]\rho =\frac{m}{V}[/tex]
Given the density and the mass of the neon, we can compute its density as shown below:
[tex]V=\frac{m}{\rho} =\frac{222g}{0.900g/L}\\\\V=247L[/tex]
Best regards!
The volume of neon in liters is 246.67 L.
To calculate the volume of neon, we use the formula below.
Formula:
D = m/V............... Equation 1Where:
D = Density of neonm = mass of neonV = Volume of neon.make V the subject of the equation.
V = m/D............... Equation 2From the question,
Given:
m = 222 gD = 0.900 g/LSubstitute these values into equation 2
V = 222/0.9V = 246.67 L.Hence, The volume of neon in liters is 246.67 L.

how an ionic compound made up of charged particles can be electrically neutral
Answer:
Explanation:
Ionic compounds are electrically neutral because the charges of the cations and anions that make up the compound cancel each other out. In the case of salt for example, sodium has a charge of positive one, and chloride has a charge of negative one. Together, they neutralize the compound.

In the reaction of: ????2O4 (g) ⇌ 2????O2(g) If the equilibrium constant is Kc = 0.513 and the initial concentration of ????2O4 = 0.0500 ????. What are the equilibrium concentrations of ????2O4 and ????O2 under these conditions?
Answer:
[N₂O₄] = 0.00411 M
[NO₂] = 0.0918 M
Explanation:
In the reaction of: N₂O₄(g) ⇌ 2 NO₂(g) If the equilibrium constant is Kc = 0.513 and the initial concentration of N₂O₄ = 0.0500 M. What are the equilibrium concentrations of N₂O₄ and NO₂ under these conditions?
Step 1: Given data
Initial concentration of N₂O₄: 0.0500 M
Equilibrium constant (Kc): 0.513
Step 2: Make an ICE chart
N₂O₄(g) ⇌ 2 NO₂(g)
I 0.0500 0
C -x +2x
E 0.0500-x 2x
Step 3: Find the value of "x"
The equilibrium constant is:
Kc = [NO₂]² / [N₂O₄]
0.513 = (2x)² / (0.0500-x)
4x² + 0.513 x -0.02565
We solve for x and we get x₁ = 0.0458942 and x₂ = −0.558894 (neglected).
Step 4: Calculate the concentrations at equilibrium
[N₂O₄] = 0.0500-x = 0.00411 M
[NO₂] = 2x = 0.0918 M

A rock with a mass of 70 grams is dropped into a graduated cylinder with 30 mL of water in it. The water level rose to 35 mL calculate the density of the rock in g/mL
Answer:
14
Explanation:
70g/(35mL-30mL)=14g/mL
If a rock with a mass of 70 grams is dropped into a graduated cylinder with 30 milliliter of water in it. The water level rose to 35 milliliters, then the density of the rock in gram / milliliter would be 14 gram / milliliter.
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
The mass of ṭhe rock = 70 grams
The volume of the rock = 35 milliliters - 30 milliliters
= 5 milliliters
The density of the rock = mass of the rock / volume of the rock
=70 grams / 5 milliliters
= 14 gram / milliliter
Thus, the density of the rock would be 14 gram / milliliter.

Solid nickel reacts with aqueous lead (II) nitrate to form solid lead. What is the net ionic equation for this reaction? • Hint: In this reaction, nickel exhibits its most common oxidation state of +2. • Be sure to include the charge for each ion in the net ionic equation. Provide your answer below: (s) + (aq) → *(n)
Answer:
Pb²⁺(aq) --> Ni²⁺(aq)
Explanation:
The equation of the reaction is given as;
Ni(s) + Pb(NO₃)₂(aq) --> Pb(s) + Ni(NO₃)₂(aq)
In writing the ionic equation, we break the aqueous compound into ions. The solid and liquid compounds are ignored.
We have;
Pb²⁺(aq) + NO₃²⁻(aq) --> Ni²⁺(aq) + NO₃²⁻(aq)
Canceling the spectator ions;
Pb²⁺(aq) --> Ni²⁺(aq)
Answer:
Ni(s)+Pb2+(aq)→Ni2+(aq)+Pb(s)
Explanation:
The complete ionic equation of this reaction is
Ni(s)+Pb2+(aq)+2 NO−3(aq)→Ni2+(aq)+2 NO−3(aq)+Pb(s)
The nitrate ions are spectator ions and can be removed from the equation, giving us
Ni(s)+Pb2+(aq)→Ni2+(aq)+Pb(s)

A 7.28 g sample of chromium metal was heated to produce chromium oxide. The weight of the compound was 10.63 g. What is the percent chromium in this compound?
Answer:
68.48%
Explanation:
The percent mass of an element in a compound tells us about the amount of such element contributed to the total compound.
In this case, 7.28 g sample of chromium metal was heated to produce chromium oxide with weight of 10.63 g. The percent mass of chromium in chromium oxide can be calculated by using the formula:
%mass of Cr = mass of Cr/mass of Chromium oxide × 100%
%mass of Cr = 7.28/10.63 × 100
%mass of Cr = 0.6848 × 100
%mass of Cr = 68.48%

What is the mass of CO2 lost at 20 min from the limestone sample?
How much CO2, in moles, was lost at 20 min from the limestone sample?
How much CO3 2- was lost at 20 min from the limestone sample?
Answer:
The mass, CO2 and CO3 from the limestone sample is discussed below in details.
Explanation:
(A) mass loss of sample of limestone after 20 min
= 0.8437g-0.5979g = 0.2458 g
From the given reaction of limestone, 2 mol of the sample gives 2 moles of CO 2.
Therefore
184.4 g ( molar mass of limestone) gives2× 44 g of carbon dioxide.
1 g of sample gives 88/184.4 g of carbon dioxide
Hence 0.2458 g sample gives
= 88/184.4 × 0.2458 g = 0.117 g carbon dioxide
(B) mole of CO 2 lost = weight/ molar mass
= 0.117 g / 44 g/mol =0.0027 mole
(C). 1 mol of limestone contain 2 mol of carbonate ion
From the reaction we know that carbonate ion of limestone is converted into carbondioxide
Hence lost carbonate ion = 0.2458 g
(D) we know that
1 mol limestone contain 1mol CaCO 3
Hence in sample present CaCO 3
= 1mole / 184.4 g × 0.8437 g= 0.00458 mol CaCO3

What are the signs of ΔH, ΔS, and ΔG for the spontaneous conversion of a crystalline solid into a gas?
Answer:
ΔH>0, ΔS>0, and ΔG<0
Explanation:
Crystalline solid → Gas
ΔG < 0 T as the reaction is Spontaneous The solid is converted into gas so the Entropy will increase as randomness is more in gas than solid, ΔS > 0using Gibbs equation
ΔG = ΔH - TΔS
as ΔG < 0 and ΔS > 0
ΔH - TΔS <0
ΔH < TΔS ⇒ΔH >0
This gives that ΔH will be Positive but it will be less than TΔS. So we need to provide some energy to convert crystalline solid into gas.
What evidence should Mitchell collect to BEST support the second law of thermodynamics?
Answer:
The Second Law of Thermodynamics poses an insurmountable problem for ... More time will make things worse for the Darwinist, not better. ... error fail-safe and proof-reading devices utilized for quality control, assembly ... No one really supports the idea that the sun + non life = life
Explanation:
According to the second law of thermodynamics, the energy of the universe is conserved but the entropy of the universe is continuously increasing.
What is the second law of thermodynamics?The second law of thermodynamics put some restrictions on the direction of heat transfer and attainable efficiencies of heat engines. This law stated that any spontaneously happening process will lead to an escalation in the entropy (S) of the universe.
This law explains that the entropy of an isolated system will never decrease with time. Mathematically, the 2nd law of thermodynamics:
ΔS (universe) > 0
where ΔS of the universe is the change in the entropy of the universe.
The second law of thermodynamics provides the criterion for the feasibility of any physical or chemical process. A physical or chemical process cannot take place unless it must follow both the 1st and 2nd laws of thermodynamics.
