These coefficients represent the number of moles of each substance that are present in a given amount of propane that undergoes complete combustion.
When propane undergoes complete combustion, the balanced equation is:
C₃H₈ + 7O2 → 4CO₂ + 4H₂O
To determine the coefficients for each compound, we can use the balanced equation and the mole ratios of the products.
The mole ratio of carbon dioxide to propane is 4:1, since there are four moles of carbon dioxide for every mole of propane that undergoes combustion.
The mole ratio of water to propane is 4:1, since there are four moles of water for every mole of propane that undergoes combustion.
The mole ratio of carbon dioxide to oxygen is 1:4, since there is one mole of carbon dioxide for every four moles of oxygen that participate in the reaction.
The mole ratio of hydrogen to oxygen is 2:4, since there are two moles of hydrogen for every four moles of oxygen that participate in the reaction.
We can use these mole ratios to write the balanced equation with the smallest whole numbers:
C₃H₈ + 7O₂ → 4CO₂ + 4H₂O
The coefficients in this equation are the same as the mole ratios, so the coefficients for each compound are:
C3H8: 1
O2: 7
CO2: 4
H2O: 4

What is the difference between an empirical formula and a molecular formula?
Answer:
The empirical formula simply states the ratios of the elements that make up the molecule, while molecular formulas specify the amounts of each element exactly, not just giving the ratio. Let's take ethane (C2H6) as an example.
Why do you think males and children are more likely to die from DHMO
Answer:
Dihydrogen Monoxide (DHMO) is perhaps the single most prevalent of all chemicals that can be dangerous to human life. Despite this truth, most people are not unduly concerned about the dangers of Dihydrogen Monoxide. Governments, civic leaders, corporations, military organizations, and citizens in every walk of life seem to either be ignorant of or shrug off the truth about Dihydrogen Monoxide as not being applicable to them. In 1997, the Dihydrogen Monoxide Research Division was formed and went online spreading the truth about DIHYDROGEN MONOXIDE. As word has spread, so too has the public awareness of Dihydrogen Monoxide and its implications involving the Internet and accessibility of such information. To that end, the DMRD's web site at DHMO.org continues to provide the most comprehensive collection of Dihydrogen Monoxide information available anywhere.
Explanation:
DHMO has been the dihydrogen monoxide. It has been responsible for the death of males and children as it causes tissue damage.
The DHMO has been the hydric acid and is one of the major constituents of acid rain. Gas has been responsible for greenhouse gas. Ingestion may lead to tissue damage with symptoms of nausea, vomiting, and electrolyte imbalance.
The companies dumping waste in the rivers and lakes have been warned for the removal of DHMO as it has been harmful to the males and children, and results in death.

Choose the aqueous solution below with the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable.
The question is incomplete, the complete question is;
Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. 0.100 m C6H12O6 0.100 m AlCl3 0.100 m NaCl 0.100 m MgCl2 They all have the same boiling point.
Answer:
AlCl3 0.100 m
Explanation:
Let us remember that the boiling point elevation is given by;
ΔTb = Kb m i
Where;
ΔTb = boiling point elevation
Kb = boiling point constant
m = molality of the solution
i = Van't Hoff factor
We can see from the question that all the solutions possess the same molality, ΔTb now depends on the value of the Van't Hoff factor which in turn depends on the number of particles in solution.
AlCl3 yields four particles in solution, hence ΔTb is highest for AlCl3 . The solution having the highest value of ΔTb also has the highest boiling point.

3 By referring to subatomic particles, explain why
an atom of
nitrogen is electrically neutral.
Answer:
Explained below
Explanation:
Atoms are said to be electrically neutral when they have the same number of protons and electrons.
Now, Nitrogen atom has a mass number of 14 and an atomic number of 7. This means that it has 7 number of protons and 7 number of electrons.
From the definition of electrically neutral atoms, it's clear that nitrogen falls into that category.
What is the freezing point of a solution of 498mL of water (solute) dissolved in 2.50 L of ethanol (solvent), C2H5OH? The density of C2H5OH is 0.789g/cm3. (Remember that water has a density of 1.0 g/cm3.)
Answer:
Freezing T° of solution is -142.4°C
Explanation:
This excersise is about colligative properties, in this case freezing point depression,
ΔT = Kf . m . i
Where ΔT = Freezing T° of solvent - Freezing T° of solution
Kf = Cryoscopic constant
m = mol/kg (molality)
i = Number of ions dissolved.
Water is not ionic, so i = 1
Let's find out m.
We determine mass of water, by density
498ml . 1 g/mL = 498 g
We convert the mass of water to moles → 498 g . 1mol/18g = 27.6 moles
We determine mass of solvent by density
2500 mL . 0.789 g/mL = 1972.5 g
Notice, we had to convert L to mL to cancel units.
1 cm³ = 1 mL
We convert the mass from g to kg → 1972.5 g . 1kg /1000g = 1.97kg
We determine m = mol/kg → 27.6mol / 1.97kg = 13.9 m
Kf for ethanol is: 1.99 °C/m
Freezing T° for ethanol is: -114.6°C
We replace at formula: - 114.6°C - Freezing T° solution = 1.99 °C/m . 13.9 m . 1
- 114.6°C - Freezing T° solution = 27.8 °C
- Freezing T° solution = 27.8°C + 114.6°C
Freezing T° Solution = - 142.4 °C

Explanation:
industrial gases cause acid rain why
because the industrial gas is very harmful for us it is made up chemical and toxic gases
Answer:
The usual culprit is burning coal.
Explanation:
This produces a lot of carbon dioxide as well as sulphur dioxide. Other industrial processes, and vehicle emissions, produce similar oxides unless they are 'scrubbed' out. They react with atmospheric moisture to produce acids like carbonic, sulphurous and nitrous acids. Which is then precipitated. It should be remembered that a volcanic eruption has this effect too.

Answer:
1. A
2. C
Explanation:
For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.
What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.
A is the correct answer.
for the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.
C is the correct answer.

Can someone help me with my stoichiometry homework, it is due tonight.
Answer:
1. 1 mole of NaCl.
2. 1 mole of H₂O.
Explanation:
The balanced equation for the reaction is given below:
HCl + NaOH —> NaCl + H₂O
From the balanced equation above,
1 mole of HCl reacted with 1 mole of NaOH to produce 1 mole of NaCl and 1 mole of H₂O.
Next, we shall determine the limiting reactant. This can be obtained as follow:
From the balanced equation above, we can see that 1 mole of HCl reacted completely with 1 mole of NaOH. Therefore, HCl is the limiting reactant and NaOH is the excess reactant since we have 3.6 moles of NaOH.
1. Determination of the amount of NaCl produced from the reaction.
NOTE: The limiting reactant is used to determine the maximum amount produced since all of it is consumed in the reaction.
The limiting reactant is HCl and the amount of NaCl produced can be obtained as follow:
From the balanced equation above, we can see that 1 mole of HCl reacted to 1 mole of NaCl.
Thus, 1 mole of NaCl was produced.
2. Determination of the amount of H₂O produced from the reaction.
From the balanced equation above, it is evident that 1 mole of HCl reacted to produce 1 mole of H₂O.
Thus, 1 mole of H₂O was produced.
