Using the provided table, determine the molar enthalpy (in kj/mol) for the reaction c₃h₈ (g) + 5 o₂ (g) → 3 co₂ (g) + 4 h₂o (g).
Considering the normal of standard enthalpy of formation, the molar enthalpy for the reaction is -2043.98 kJ.
The balanced reaction is:
C₃H₈ (g) + 5 O₂ (g) → 3 CO₂ (g) + 4 H₂O (g)
The normal or standard enthalpy of formation (also sometimes called the normal heat of formation), is represented by ΔHf and is the enthalpy change when a mole of compound is formed from its elements in the normal state (that is, in the state of aggregation and more stable allotropic form to which said elements are found under standard conditions).
The enthalpy of formation may be positive, an endothermic reaction, or negative, an exothermic reaction.
In summary, the enthalpy of formation of a compound is defined as the enthalpy of reaction of the reaction in which a mole of said compound is formed from its elements in their most stable states of aggregation.
The use of enthalpies of formation allows to calculate enthalpies of reaction as follows: The standard enthalpy of a reaction is equal to the sum of the standard molar enthalpies of formation of the products minus the sum of the standard molar enthalpies of the formation of the reactants, multiplied respectively by the stoichiometric coefficients that appear in the fitted equation.
In this case, you have ΔHf values in kJ/mol for:
C₃H₈(g) = -103.8O₂(g) = 0CO₂(g) = -393.5H₂O(g) =- 241.82So, being: ΔH° = ΣnHfº (products) - ΣmHfº (reactants); n and m are total moles
and replacing the values:
ΔH° = [4 moles× (-241.82 [tex]\frac{kJ}{mol}[/tex]) + 3 moles× (-393.5 [tex]\frac{kJ}{mol}[/tex])] - [5 moles× (0 [tex]\frac{kJ}{mol}[/tex]) + 1 moles× (-103.8 [tex]\frac{kJ}{mol}[/tex])]
Solving:
ΔH° = [-967.28 kJ - 1180.5 kJ] - [0 kJ - 103.8 kJ]
ΔH° = -2147.78 kJ - [-103.8 kJ]
ΔH° = -2147.78 kJ + 103.8 kJ
ΔH° = -2043.98 kJ
In summary, the molar enthalpy for the reaction is -2043.98 kJ.

The highway department is planning to build a picnic area for motorists along a major highway. It is to be rectangular with an area of 5,000 square yards and is to be fenced off on the three sides not adjacent to the highway. What is the least amount of fencing that will be needed to complete the job?.
The least amount of fencing would need to cover the picnic area of 100 yards length and 50 yards width.
Let x represent the length of the picnic area and y represent the width of the picnic area. Also x is the side adjacent to the highway.
Also, the area is 5,000 square yards, hence:
5000 = length * width
5000 = xy
y = 5000/x
The perimeter of the area is:
Perimeter (P) = x + y + y
P = 2y + x
P = 2(5000/x) + x = 10000/x + x
The least amount of fencing is at dP/dx = 0:
dP/dx = -10000/x² + 1
0 = -10000/x² + 1
10000/x² = 1
x² = 10000
x = 100 yards
y = 5000/x = 5000/100
y = 50 yards
The least amount of fencing would need to cover the picnic area of 100 yards length and 50 yards width.

Explanation:
A craft vendor must sell at least $300 worth of merchandise to make a profit. Scarves sell for $10 each and hats sell for $20 each. She expects to sell at least 20 items. The lines on the graph represent the situation in which she makes a profit. On a coordinate plane, 2 straight lines are shown. The x-axis shows number of scarves sold, from 0 to 20, and the y-axis shows number of hats sold, from 0 to 20. The first solid line has a negative slope and goes through (2, 14) and (14, 8). Everything above the line is shaded. The second solid line has a negative slope and goes through (0, 20) and (20, 0). Everything to the right of the line is shaded. In which section of the graph does the actual solution lie? 1 2 3 4.
Answer:
The answer is 1.
Explanation: I just got it on Edge.
The x-axis shows number of scarves sold, from 0 to 20, and the y-axis shows number of hats sold, from 0 to 20 is the section of the graph does the actual solution lie. Hence, option A is correct.
What is negative slope?If a line appears to go down and to the right, it has a negative slope (or up and left). This indicates mathematically that as x rises, y falls.
For instance, the incidence of lung cancer declines as more people (x) stop smoking, resulting in a lower (y) number of new cases. This relationship's graph has a downward slope.
The slope of a line is positive if the line's graph slopes upward from left to right. The slope is negative if the line's graph slopes from left to right.
Be aware that a line's positive slope causes it to slope upward from left to right. Remember that a line with a negative slope descends from left to right. Remember that a line's slope is zero when it is horizontal.
Thus, option A is correct.
