The formula for propane is c3h8 what would you need to know to answer how much energy is required to combust propane vs gasoline
Answers
For propane combustion, the balanced equation is:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
This equation shows that one molecule of propane (C₃H₈) reacts with five molecules of oxygen (O₂) to produce three molecules of carbon dioxide (CO₂) and four molecules of water (H₂O).
For gasoline, the composition can vary, and the exact balanced equation would depend on the specific hydrocarbon components present in the gasoline.
Once you have the balanced equations, you would also need to know the standard enthalpy of formation (ΔH°f) values for the reactants and products involved in the combustion reactions. These values represent the change in enthalpy (energy) during the formation of one mole of a substance from its constituent elements, at standard conditions.
With the balanced equations and the ΔH°f values, you can apply the principles of thermochemistry and use the Hess's Law to calculate the energy released during the combustion reactions of propane and gasoline. The difference in energy released would indicate the difference in energy required to combust propane vs gasoline.

Answers
The reaction is product favored under standard conditions at 329 K.
The balanced chemical reaction is given as follows:
2 NH₃ + 3 N₂O → 4 N₂ + 3 H₂O
ΔH° = 329 K
ΔS° = 1.70 KJ / K
∴ ΔG° = ΔH° - TΔS°
⇒ΔG° = 329 KJ - 329 × 1.70 KJ / K
⇒ΔG° = 329 KJ - 559.3 KJ
⇒ΔG° = -230.3 KJ
As ΔG° has negative value for the above reaction that is ΔG°<0 so the reaction is product favored.

=4.20) and 0.240M sodium benzoatc. How many milliliters of each solution should be mixed to prepare this buffer? benzoic acid:
Previous question
Answers
To prepare the pH 4.00 buffer solution, you should mix approximately 61.35 mL of the 0.100 M benzoic acid solution with 38.65 mL of the 0.240 M sodium benzoate solution.The ratio of benzoic acid to sodium benzoate in the buffer solution using the Henderson-Hasselbalch equation.
To prepare a pH 4.00 buffer solution using benzoic acid and sodium benzoate, we need to calculate the appropriate volumes of the 0.100 M benzoic acid and 0.240 M sodium benzoate solutions.
First, we need to determine the ratio of benzoic acid to sodium benzoate in the buffer solution. The Henderson-Hasselbalch equation can help us with this calculation:
pH = pKa + log([A-]/[HA])
Given that the pH is 4.00 and pKa is 4.20, we can rearrange the equation:
log([A-]/[HA]) = pH - pKa
log([A-]/[HA]) = 4.00 - 4.20
log([A-]/[HA]) = -0.20
Next, we take the antilog of -0.20 to find the ratio of [A-] to [HA]:
[A-]/[HA] = antilog(-0.20)
[A-]/[HA] = 0.63
The ratio of [A-] to [HA] is 0.63.
Now, let's calculate the volumes of each solution needed. Let's assume x represents the volume (in mL) of the 0.100 M benzoic acid solution and y represents the volume (in mL) of the 0.240 M sodium benzoate solution.
Since the total volume is 100.0 mL, we have the equation: x + y = 100
Considering the ratio of [A-] to [HA] as 0.63, we can write the equation: y/x = 0.63
Solving these two equations simultaneously will give us the volumes of each solution:
x + y = 100
y/x = 0.63
By substituting y = 0.63x from the second equation into the first equation, we get:
x + 0.63x = 100
1.63x = 100
x = 61.35 mL (rounded to two decimal places)
Substituting this value back into the equation x + y = 100, we find:
61.35 + y = 100
y = 38.65 mL (rounded to two decimal places)
Therefore, to prepare the pH 4.00 buffer solution, you should mix approximately 61.35 mL of the 0.100 M benzoic acid solution with 38.65 mL of the 0.240 M sodium benzoate solution.

In a school’s laboratory, students require 50.0 ml of 2.50 m h2so4 for an experiment, but the only available stock solution of the acid has a concentration of 18.0 m. what volume of the stock solution would they use to make the required solution? use m subscript i v subscript i equals m subscript f v subscript f.. 0.900 ml 1.11 ml 6.94 ml 7.20 ml
Answers
The volume of stock solution they use to make the required solution is 6.94mL.
How we calculate the volume?To calculate the value of required volume we will use the below equation:
M₁V₁ = M₂V₂, where
M₁ = molarity of stock solution = 18M
V₁ = volume of stock solution = to find?
M₂ = molarity of H₂SO₄ solution = 2.50M
V₂ = volume of H₂SO₄ solution = 50mL
On putting all these values on the above equation and calculate for the value of V₁ as:
V₁ = (2.50)(50) / (18) = 6.94mL

what is the relationship between the tides on earth and phase of the moon
Answers
Answer:
High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.
Explanation:
The greatest difference between high and low tide is around New Moon and Full Moon. During these Moon phases, the solar tide coincides with the lunar tide because the Sun and the Moon are aligned with Earth, and their gravitational forces combine to pull the ocean's water in the same direction.
