When stress builds faults, what happens is that: B. Rock can bend and break.
A rock can be defined as a solid naturally occurring landform that is made up of various minerals.
In Geology, stress can be defined as a force that acts on a rock per unit area.
There are four (4) main types of of stress associated with rocks and these are:
Tension: it is a stress typically caused by rocks pulling apart, which makes them to either increase in length or break apart.Shearing: it is a stress typically caused by rocks being pushed in opposite direction due to the effect of parallel forces.Compression: this is a stress that is caused by rocks pushing together, which makes them to either bend (fold) or fracture (break).Confining stress: it is a stress typically caused by rocks being pushed down by the weight of any material atop it.In conclusion, rocks can bend and break when stress builds up faults in them.

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)

Predict and write the charges and symbols of the monatomic ions formed by the following atoms: bromine rubidium
Answer: The monoatomic ions formed by bromine and rubidium are [tex]Br^-[/tex] and [tex]Rb^+[/tex] respectively.
Explanation:
When an atom accepts an electron negative charge is created on atom and is called as anion. When atom loses an electron positive charge is created on atom and is called as cation.
The atomic number of bromine and rubidium is 35 and 37 respectively. So, the number of electrons is equal to 35 and 37 respectively. Bromine will gain one electron and rubidium will lose one electron to attain stable electronic configuration to form [tex]Br^-[/tex] and [tex]Rb^+[/tex] respectively.

Peptides can be separated using an ion‑exchange column based on their isoelectric (pI) values. At which pH values would two different peptides, one with a pI of 5.3 and the other with a pI of 8.5 , bind to a cation‑ and anion‑exchange column? Each peptide may be capable of binding to each column at more than one pH value.
Answer:
At pH 3.5:
Peptide A with pI 5.1 and peptide B with pI 8.5 will both bind to the anion-exchange column.
At pH 6.5:
Peptide A with pI 5.1 will bind to the cation-exchange column, while peptide B with pI 8.5 will bind to the anion-exchange column.
At pH 10.8:
Peptide A with pI 5.1 and peptide B with pI 8.5 will both bind to the cation-exchange column.
Explanation:
Ion-exchange column chromatography is used for separating proteins and other molecules in a solution based on differences in net charge. Negatively charged molecules bind to positively charged solid supports called the anion-exchange column, whereas, positively charged molecules bind to negatively charged solid supports known as cation-exchange column.
A peptide can acquire a net charge if the pH of the medium is either above or below its isoelectric point,pI. At pH above pI, the peptide acquires a net negative charge and can bind to a positive support. At pH above pI, the peptide acquires a net positive charge and can bind to a negative support. The greater the difference between pH and pI, the tighter the peptide will bind to the column.
At pH 3.5:
Peptide A with pI 5.1 and peptide B with pI 8.5 will both bind to the anion-exchange column.
At pH 6.5:
Peptide A with pI 5.1 will bind to the cation-exchange column, while peptide B with pI 8.5 will bind to the anion-exchange column.
At pH 10.8:
Peptide A with pI 5.1 and peptide B with pI 8.5 will both bind to the cation-exchange column.

Which of the following correctly compares the radii of F and F−?
A) F has a smaller radius than F− because an additional electron causes greater repulsion in F−.
B) F has a larger radius than F− because an additional electron causes greater repulsion in F.
C) F has a smaller radius than F− because F− has an additional energy shell.
D) F has a larger radius than F− because F has an additional energy shell.
F has a smaller radius than F− because F− has an additional energy shell correctly compares the radii of F and F−. The correct option is C.
Thus, Compared to oxygen, fluorine is a stronger electronegative element. The outermost electrons of fluorine are gripped by the nucleus more tightly than oxygen because fluorine has a high electronegativity.
It takes more energy to remove the outermost electron of fluorine than it does to remove the outermost electron of oxygen. Fluorine has a higher ionization energy than oxygen as a result.
An atom's energy is determined by how much energy it gains or loses as a result of chemical processes that result in electron loss or gain. Exothermic reactions are those in which energy is released, and endothermic reactions are those in which energy is absorbed.
Exothermic reactions produce negative energy, which is why energy is given a negative sign.
Thus, F has a smaller radius than F− because F− has an additional energy shell correctly compares the radii of F and F−. The correct option is C.

The specific heat of ethanol (C2H5OH) is 2.46 J/g ° C. What is the heat capacity of 1.00 kg of ethanol?
Answer:
The total heat required is 4088.6 J
Explanation:
We have three processes which involve heat absorption. We have to calculate the heat of each process and then to calculate the total heat.
1- liquid ethanol is heated from 25ºC (298 K) to the boiling point 78.5ºc (351.5 K). We use specifi heat of liquid ethanol to calculate the heat absorbed in this part:
H1= m x Sh x ΔT
H1= m x Sh x (Tfinal - Tinitial)
H1= 3.95 g x 2.45 J/g.K x (351.5 K -298 K)
H1= 517.7 JExplanation:
What is the final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L
Answer: The final concentration of a solution is 0.350 M
Explanation:
According to the dilution law,
[tex]C_1V_1=C_2V_2[/tex]
where,
[tex]C_1[/tex] = concentration of concentrated acid solution = 12.0 M
[tex]V_1[/tex] = volume of concentrated acid solution = 35.0 ml
[tex]C_2[/tex] = concentration of diluted acid solution= ?
[tex]V_2[/tex] = volume of another acid solution= 1.20 L = 1200 ml
( 1L=1000ml)
Putting in the values:
[tex]12.0\times 35.0=C_2\times 1200[/tex]
[tex]C_2=0.350M[/tex]
The final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L is 0.350 M

The greatest absorbance occurs when the solution and beam color are the ______ because the solution color appearance is the color being ___________ by the solution.
Answer:
Same
Absorbed
Explanation:
When you are dealing with solutions the best way to tell that something has been absorbed is when the solution and the beam color are the same, since they have the same color you can be sure that the color has been absorbed properly and the greatest absorbance has occured.
The fill in the blanks should be filled with the same and absorbed.
The following information should be considered:
At the time when you deal with the solutions, the best way is that something should be absorbed at the time when the solution & beam color should be similar. As it contains the similar color so the color should been absorbed properly & the highest absorbance should be arise.Therefore we can conclude that the fill in the blanks should be filled with the same and absorbed.
