When there is a conflict and if a friend responding to conflict with confrontation it may affect positively or negatively both ways depend how he responds or confront the other person he has a conflict with. But normally people alienate with the person being confrontational. A friend should try to resolve the conflict by making an amicable solution.
if it is used correctly it could help in making the relationship strong, however, confronting by attacking them verbally, insult them, or talking loudly among the group of people can escalate the conflict.
I will advise him to be cautious of the approach as it may positively or negatively affect the situation.
What is Confrontation?This is the process which involves directly engaging one another in the course of a dispute between them.
This method however could either resolve the conflict or worsen it which is why special approach should be taken by being calm and being respectful to the other party involved.

When 577 J of energy is added to 32.3 g of aluminum at 17.4ºC, the temperature increases to 46.6ºC. What is the specific heat of aluminum?
Answer:
0.612 J/g°C
Explanation:
Using the formula as follows:
Q = m × c × ∆T
Where;
Q = amount of heat (Joules)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C) i.e. final - initial temperature
According to the information provided in this question;
Q = 577 J
m = 32.3 g
c = ?
Final temp = 46.6ºC, initial temp. = 17.4°C
∆T = (46.6 - 17.4) = 29.2°C
Using Q = m × c × ∆T
c = Q ÷ m.∆T
c = 577 ÷ (32.3 × 29.2)
c = 577 ÷ 943.16
c = 0.6117
c = 0.612 J/g°C

need help asap, In this reaction how many units of B are required to form 40 units of C? A+2B--->C
Answer:
80 units B
Explanation:
Equation for the reaction is given below:
A + 2B —> C
From the equation above,
2 units of B reacted to produce 1 unit to C.
Finally, we shall determine the unit of B needed to produce 40 units of C. This can be obtained as follow:
From the equation above,
2 units of B reacted to produce 1 unit to C.
Therefore, x unit of B will react to produce 40 units of C i.e
x unit of B = 2 × 40
x unit of B = 80 units
Thus, 80 units B is needed for the reaction.

If the experiment contains 75.0 grams of O2, how many grams of H2O should be produced?
Answer: 33.75g H2O
Explanation:
75g O2 (1 mol O2/32g O2) (4 mol H2O/5 mol O2) (18g H2O/1 mol H2O) = 33.75g H2O
This is a stoichiometric calculation in which 75 is multiplied by 1, 4, and 18 (the top numbers), and then divided by (32 x 5 x 1), which are the bottom numbers.

If we add 22.5 g of HCl to 45.8 g of water, what is the percent by mass of HCl in the solution?
Answer:
[tex]\%m/m=33.0\%[/tex]
Explanation:
Hello there!
In this case, since the percent by mass of a solute in a solution is computed via the following division:
[tex]\%m/m=\frac{m_{solute}}{m_{solute}+m_{solvent}} *100\%[/tex]
Next, given the mass of HCl and that of water, we plug them in to obtain:
[tex]\%m/m=\frac{22.5g}{22.5g+45.8g} *100\%\\\\\%m/m=33.0\%[/tex]

2C2H2 + 502 = 4CO2 + 2H20
when 20000g of 2C2H2 + 5O2 = how much 4CO2?
Answer:
6.761 × 10⁴ g
Explanation:
Step 1: Write the balanced combustion reaction
2 C₂H₂ + 5 O₂ ⇒ 4 CO₂ + 2 H₂O
Step 2: Calculate the moles corresponding to 20000 g of C₂H₂
The molar mass of C₂H₂ is 26.038 g/mol.
20000 g × 1 mol/26.038 g = 768.11 mol
Step 3: Calculate the moles of CO₂ produced from 768.11 moles of C₂H₂
The molar ratio of C₂H₂ to CO₂ is 2:4.
768.11 mol C₂H₂ × 4 mol CO₂/2 mol C₂H₂ = 1536.2 mol CO₂
Step 4: Calculate the mass corresponding to 1536.2 moles of CO₂
The molar mass of CO₂ is 44.01 g/mol.
1536.2 mol × 44.01 g/mol = 6.761 × 10⁴ g

An FCC iron-carbon alloy initially containing 0.20 wt% C is carburized at an elevated temperature and in an atmosphere wherein the surface carbon concentration is maintained at 1.0 wt%. If after 51 h the concentration of carbon is 0.35 wt% at a position 3.9 mm below the surface, determine the temperature at which the treatment was carried out. You will need to use data in the two tables below to solve this problem.
Answer:
Explanation:
[tex]\text{From the information given:}[/tex]
[tex]C_o = 0.20 \ wt\% \\ \\ C_s = 1 \ wt\% \\ \\ t = 51 \ h \\ \\ x = 3.9 \ mm \\ \\ C_x = 0.35 \ wt\%[/tex]
[tex]\text{Using Fick's 2{nd} \ law \ of \ diffusion;} \\ \\ \dfrac{C_x- C_o}{C_s-C_o}= 1 - erf ( \dfrac{x}{2\sqrt{Dt}})[/tex]
[tex]\dfrac{0.35-0.20}{1-0.20}= 1 - erf ( \dfrac{x}{2\sqrt{Dt}})[/tex]
[tex]0.1875 = 1 - erf ( \dfrac{x}{2\sqrt{DT}}) \\ \\ erf ( \dfrac{x}{2\sqrt{DT}}) = 1 - 0.1875 \\ \\ erf ( \dfrac{x}{2\sqrt{DT}}) = 0.8125[/tex]

∴
[tex]\dfrac{z-0.90}{0.95-0.90}= \dfrac{0.8125-0.7970}{0.8209-0.7970}[/tex]
[tex]\dfrac{z-0.90}{0.05}= \dfrac{0.0155}{0.0239}[/tex]
[tex]z = 0.9324[/tex]
[tex]\text{To determine the diffusion coefficient;}[/tex]
[tex]erf (0.9324) = 0.8125 = erf (\dfrac{x}{2\sqrt{Dt}}) \\ \\[/tex]

You heat water and olive oil in two separate pans for a delicious new pasta recipe. The pans are the same temperature, but only the water is boiling! Why?
A
Olive oil has weaker intermolecular forces than water. This makes the intermolecular forces in oil easier to break, and keeps the molecules stuck together in a liquid state.
B
Water has weaker intermolecular forces than olive oil. This makes the intermolecular forces easier to break, allowing the individual water molecules to separate and change to a gas.
C
Water is losing electrons more quickly than olive oil is. The electrons float to the surface of the water, and their movement allows the phase change to happen.
Answer:
I think A is the correct answer
Answer: the answer is B 100%

A chemist has a sample of 1.88 M HCl. What volume of the sample does he require to prepare 200 mL of 0.45 M HCl?
Answer: v = 200 ml · 0.45 M/ 1.88 M
Explanation: when solution is diluted, amount of substance
is same and n= c · V v1 = v2 · c2 / c1
The appropriate answer is "47.87 mL".
Given values are:
Concentration of undiluted HCl, [tex]C_1=1.88 \ M[/tex]Concentration of diluted HCl, [tex]C_2=0.45 \ M[/tex]Volume of diluted HCl, [tex]V_2=200 \ mL[/tex]By using the dilution equation, we get
→ [tex]C_1V_1=C_2V_2[/tex]
or,
→ [tex]V_1=\frac{C_2V_2}{C_1}[/tex]
By substituting the given values, we get
→ [tex]=\frac{0.45\times 200}{1.88}[/tex]
→ [tex]=\frac{90}{1.88}[/tex]
→ [tex]= 47.87 \ mL[/tex]
Thus the above answer is correct.

For each of the solutions from above order the following in increasing polarity (from lowest to highest): solvent, more polar molecule, less polar molecule, silica gel. If the difference cannot be determined, indicate this by entering N/D. Note you might have to use a bit of logic and consider the properties of each. Useful information is found in the lab manual and student guide.

Answer:
Solvent, less polar molecule, more polar molecule, silica gel
Explanation:
Solvent has lowest polarity but less polar molecule has more polarity than solvent. The more polar molecule has higher polarity value whereas silica gel has the highest polarity. The polarity of compounds is due to the difference of electronegativity values of the elements that bonded with each other. The difference of electronegativity value is high between silicon and oxygen is responsible for high polarity of silica gel.
