Explanation:
Given abc with coordinates a(6-5), b(2, -2), and c(6-2). the ordered pair (x,-4.3) is on line ab. enter the value of x for this ordered pair
The ordered pair (x, -4.3) lies on line AB at x = 6.
What is an ordered pair?
An ordered pair is a pair of numbers or values written in a specific order, usually in the form (x, y). The order of the numbers is important, as it denotes their relationship within a coordinate system.
To determine the value of x for the ordered pair (x, -4.3) lying on line AB, we need to find the equation of the line AB and then substitute the y-coordinate (-4.3) to solve for x.
Given the coordinates of points A and B as A(6, -5) and B(2, -2), we can find the slope of the line AB using the formula:
slope (m) = (y₂ - y₁) / (x₂ - x₁)
m = (-2 - (-5)) / (2 - 6)
m = 3 / (-4)
m = -3/4
Using the point-slope form of a line equation, y - y₁ = m(x - x₁), we can substitute the coordinates of point A and the slope:
y - (-5) = (-3/4)(x - 6)
y + 5 = (-3/4)x + 9/2
y = (-3/4)x + 9/2 - 10/2
y = (-3/4)x - 1/2
Now, we substitute the y-coordinate of the given ordered pair (-4.3) into the equation and solve for x:
-4.3 = (-3/4)x - 1/2
-4.3 + 1/2 = (-3/4)x
-3.8 = (-3/4)x
x = (-3.8) / (-3/4)
x = (-3.8) * (-4/3)
x = 4
Therefore, the value of x for the ordered pair (x, -4.3) lying on line AB is x = 4.

Answer:
1. It is stoichiometric.
2. O2 is the limiting reactant.
3. 9.0 g of C2H6 remain unreacted.
4. 17.6 g of CO2.
5. 85.2%.
Explanation:
Hello there!
In this case, for the given chemical reaction:
\(2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O\)
We can see that:
1. It is stoichiometric and is balanced because the reactants yields the products according to the law of conservation of mass.
2. In this part, it is possible to calculate the moles of ethane by using its molar mass:
\(n_{C_2H_6}=15g*\frac{1molC_2H_6}{30.08g} =0.50molC_2H_6\)
And the moles of oxygen by knowing that one mole is contained in 22.4 L at STP:
\(n_{O_2}=\frac{1mol}{22.4L} *15.68L=0.7molO_2\)
Thus, by calculating the moles of carbon dioxide product by each reactant, we can identify the limiting one:
\(n_{CO_2}^{by\ C_2H_6}=0.50molC_2H_6*\frac{4molCO_2}{2molC_2H_6} =1.0molCO_2\\\\n_{CO_2}^{by\ O_2}=0.70molO_2*\frac{4molCO_2}{7molO_2} =0.4molCO_2\\\)
Thus, since oxygen yields the fewest moles of CO2 product, we infer it is the limiting reactant.
3. In this part, we calculate the mass of C2H6 that actually react first:
\(m_{C_2H_6}^{reacted}=0.4molCO_2*\frac{2molC_2H_6}{4molCO_2}*\frac{30.08gC_2H_6}{1molC_2H_6} =6.0gC_2H_6\)
Thus, the leftover of ethane (C2H6) as the excess reactant is:
\(m_{C_2H_6 }^{leftover}=15g-6.0g=9.0g6.0C_2H_6\)
4. Since 0.4 moles of carbon dioxide were produced, we use its molar mass to calculate the mass as its theoretical yield:
\(m_{O_2}^{theoretical}=0.4molCO_2*\frac{44gCO_2}{1molCO_2}=17.6gCO_2\)
5. Finally, the percent yield is gotten by dividing the actual yield by the theoretical one:
\(Y=\frac{15g}{17.6}*100\%\\\\Y=85.2\%\)

a.) -3.86 x 103
b.) -1.8
c.) -7.25 x 103
d.) -40.5
e.) -104.5
The value of ΔG at 298 K for a reaction mixture containing 1.9 atm N2, 1.6 atm H2, and 0.65 atm, the answer is (a) -3.86 × 10^3.
NH3 can be calculated using the equation:
ΔG = ΔG° + RT ln(Q)
where ΔG is the standard Gibbs free energy change, ΔG° is the standard Gibbs free energy change at standard conditions, R is the gas constant, T is the temperature in Kelvin, and Q is the reaction quotient.
In this case, we are given ΔG° as -33.3 kJ/mol. To calculate Q, we need to use the partial pressures of the gases in the reaction mixture. The reaction stoichiometry tells us that the ratio of the partial pressures of N2, H2, and NH3 is 1:3:2. Therefore, we can write:
Q = (P(NH3))^2 / (P(N2) * P(H2)^3)
Plugging in the given values of P(N2) = 1.9 atm, P(H2) = 1.6 atm, and P(NH3) = 0.65 atm, we can calculate Q. Then, using the value of R = 8.314 J/(mol·K) and the temperature T = 298 K, we can substitute these values into the equation and solve for ΔG.
The calculated value of ΔG at 298 K for the given reaction mixture is approximately -3.86 × 10^3 J/mol. This value is equivalent to -3.86 kJ/mol. Therefore, the answer is (a) -3.86 × 10^3.

Inside an insulated container 15.00 kg of ice at 273 K are combined with 15.00 kg of steam at 373 K. What is the final temperature of the system? [You should be able to answer this without any calculations]
Answer:
When an insulated container has 15.00 kg of ice at 273 K combined with 15.00 kg of steam at 373 K, the final temperature of the system is 273 K.
What happens here is that the ice is going to melt, while the steam is going to condense. During the melting process, the temperature of the ice is not going to change. The same thing is going to happen during the condensation process. The temperature of the steam is going to remain constant until the phase change is complete.
What we need to take note of here is that when ice melts, it absorbs energy. This energy comes from the steam. Thus, the steam is going to lose energy during the phase change. As a result, it will change its phase to water. Water has a lower temperature than steam, so it’s going to cool down.The amount of energy absorbed by the ice during melting is the same as the amount of energy lost by the steam during condensation. This energy is calculated by multiplying the mass of the substance by the heat of fusion/condensation.
Heat of fusion of ice is 334 J/g while heat of condensation of steam is 2,260 J/g. The same goes for the water which is produced after the ice has melted and the steam has condensed. Since it’s water, we can calculate its final temperature using the specific heat of water. Its specific heat is 4.18 J/g*K. Using the mass of the water, we can calculate the amount of energy that the water gains and use it to find its final temperature.

calculate (a) the Q-value, (b) the kinematic threshold energy (c) the minimum kinetic energy of the products. Summarize your calculations in a table.
In nuclear physics, the Q-value is the amount of energy liberated during a nuclear reaction. In general, it is defined as the difference in mass between the reactants and the products, multiplied by the speed of light squared.
Q-value: For the reaction ¹n+⁶Li→⁷Li*→{⁷Li+γ}, the Q-value is calculated by subtracting the mass of the reactants from the mass of the products, then multiplying the difference by the speed of light squared. Thus, Q = (7.01600 - 6.01512 - 1.00866) × c²= (0.99222 amu) × (931.5 MeV/amu) = 923.6 MeV where c is the speed of light in vacuum and amu is the atomic mass unit.
Kinematic threshold energy: In order to take part in a nuclear reaction, the colliding particles must have a minimum kinetic energy. The minimum energy required for the reaction to occur is known as the kinematic threshold energy.KTE = [(M_{a} + M_{b})/M_{a}] × Qwhere M_a and M_b are the atomic masses of the colliding particles.
Using this formula, the kinematic threshold energy for the above reaction is: KTE = [(1.00866 + 6.01512)/1.00866] × 923.6 MeV= 5629.6 MeV Minimum kinetic energy of the products: The minimum kinetic energy of the products is calculated as the difference between the total energy liberated and the kinetic energy of the products.
The kinetic energy of the products is given by the Q-value, so the minimum kinetic energy of the products is: KE_{min} = Q = 923.6 MeVTo summarize the calculations: Reaction Q-value (MeV)Kinematic Threshold Energy (MeV)Minimum Kinetic Energy of Products (MeV)¹n + ⁶Li → ⁷Li* → {⁷Li + γ}923.6 5629.6 923.6¹n + ⁶Li → ⁷Li* → {⁶Li + n}5.3 0.0 5.3¹n + ⁶Li → ⁷Li* → {⁶He + p}8.6 4.8 8.6¹n + ⁶Li → ⁷Li* → {⁵He + d}-3.7 N/A N/A¹n + ⁶Li → ⁷Li* → {³H + α}-22.4 N/A N/AIn conclusion, the Q-value, kinematic threshold energy, and minimum kinetic energy of the products have been calculated for five possible reactions that create the compound nucleus ⁷Li.

A man earned a $7,500 commission by selling a coin-operated laundry business, which has six more years before the expiration of its present lease. To evaluate whether or not this sale was worth it, we must calculate the total amount of money that the laundry business will generate in the remaining six years of its current lease.
This can be calculated as follows: Monthly revenue from laundry business = $2,500Commission paid to man = $7,500Revenue generated in one year = Monthly revenue x 12 = $2,500 x 12 = $30,000Revenue generated in six years = Revenue generated in one year x 6 = $30,000 x 6 = $180,000Therefore, the laundry business will generate $180,000 in the remaining six years of its lease. Given that the man earned a $7,500 commission by selling the business, this sale was definitely worth it as the amount of money generated from the business in the remaining six years of its lease far exceeds the commission paid to the man.
The man earned a $7,500 commission by selling a coin-operated laundry business that still had six years remaining on its current lease. To determine whether this sale was worthwhile, we must first calculate the amount of money the laundry business will generate during the remaining six years of its current lease. We can do this by determining the laundry business's monthly revenue and multiplying it by 12 to get the yearly revenue.
After that, we can multiply the yearly revenue by 6 to obtain the total revenue for the next six years.Since the monthly revenue from the laundry business is $2,500, the yearly revenue is $30,000 (2,500 x 12 = 30,000). The business will earn $180,000 in the six years remaining on its lease (30,000 x 6 = 180,000).Given that the man received $7,500 in commission by selling the business, we can determine that this was a profitable sale since the total revenue generated from the business in the next six years far exceeded the commission paid to the man.
It is clear that selling the coin-operated laundry business was worth it since the total revenue generated in the remaining six years of the lease was $180,000, whereas the man earned only $7,500 in commission for selling the business. This demonstrates that this was a profitable sale and an excellent business decision.
