The volume of water vapour gas that would be produced will be 2,581.73 L
Stoichiometric calculationsFrom the equation of the reaction, the mole ratio of propane to oxygen is 1:5.
Mole of 535.55 grams of propane = 535.55/44.1 = 12.12 moles
Mole of 2665.06 grams of oxygen = 2665.06/32 = 83.28 moles
Going by the mole ratio, it appears propane is limiting while oxygen is in excess.
From the equation, 1 mole of propane produces 4 moles of water vapour. Thus, the equivalent mole of water vapour will be:
12.12 x 4 = 48.48 moles.
Using the ideal gas equation: pv = nRt
v = nRT/p = 48.48 x 0.08206 x 623/0.96 = 2,581.73 L

what is the frequency of a wavelength if its wavelength is 3.6 x 10^-9m and its velocity is 3.o x 10^8 m/s
Answer:
Frequency of the wave = 8.33 × 10¹⁶ Hz
Explanation:
• We can use the wave equation to solve this problem:
v = f λ
where:
v = velocity of wave (3.0 × 10⁸ m/s)
f = frequency of wave (?)
λ = wavelength of wave (3.6 × 10⁻⁹ m)
• Substituting these values into the equation:
3.0 × 10⁸ = f × 3.6 × 10⁻⁹
f = (3.0 × 10⁸) ÷ (3.6 × 10⁻⁹)
f = 8.33 × 10¹⁶ Hz
what is the frequency of a photon with an energy of 4.56 x 10-19J?
Answer:
The wavelength of a photon with an energy of 4.56×10⁻¹⁹ J is 463nm (nanometer)
Define the wavelength of a photon.
Each photon has a wavelength and a frequency. The wavelength is defined as the distance between two peaks of the electric field with the same vector.
A photon is the smallest element of electromagnetic radiation. You can think of a photon as a packet of energy travelling at the speed of light. There is no constant wavelength of a photon, it is dependent on how much energy the photon carries.
The mathematical relationship can be written as
E=hc/ λ
In terms of wavelength,
λ=hc/E
- h is planks constant
- c is the speed of light
- E is the energy of the photon
Where h = 6.626×10⁻³⁴ J⋅s is Planck’s constant and c = 3×10⁸ m/s is the speed of light.
If E = 4.56×10⁻¹⁹ J then λ = 463nm (nano meter)
Hence, the wavelength of a photon with an energy of 4.56×10⁻¹⁹ J is 463nm(nanometer)

Uric acid can collect in joints, giving rise to a medical condition known as gout. If the pKa of uric acid is 3.89, what is the pH of a 0.0140 M solution of uric acid?
Answer:
The pH of the solution is 2.873
Explanation:
Given:
Pka = 3.89pH of a 0.0140 MLet the solution of the uric acid be HA. We have to set up the ICE table as follows;
HA(aq) + H20(l) ⇄ H3O^+(aq) + A^-
I 0.0140 0 0
C -x +x +x
E 0.0140 - x x x
Ka = 10^-(pka)
= 10^-3.89
= 1.28 x 10^-4
Ka = [H+] * [A-]/[HA]
=> 1.28 x 10^-4 = [H+]^2 / 0.0140
=>[H+]^2 = 1.28 x 10^-4 x 0.014
=> [ H+] = 1.338656 x 10^-3
so pH = - log [ H+ ] = - log 1.338656 x 10^-3
= 3 - log 1.338656

a compound with a molar mass of 92g/mol contains 0.3955g of nitrogen and 0.904g of oxygen. Determine the empirical and molecular formula
Answer:
Empirical: NO2. Molecular: N2O4
Explanation:
In order to determine the empirical formula, we divide each element's mass by their respective molar mass:
N: 0.3955g/14.01 g/mol = 0.02823 mol
O: 0.904g/16.00 g/mol = 0.0565 mol
Next, we take the smallest value and multiply it till it is close enough to an integer:
0.02823 x 40 = 1.12 Close enough to 1.
0.0565 x 40 = 2.26. Close enough to 2.
Therefore, the Empirical Formula is: NO2
Next, we determine how much the Empirical formula weighs and see if it matches 92g/mol:
14.01 g/mol + 2(16.00 g/mol) = 46.01 g/mol
We can assume this is roughly half of 92 g/mol so we can multiply each subscript by 2 to match the weight.
Therefore, the Molecular formula is N2O4

The hydronium ion concentration of a solution is 2.4 x 10-4.
a. Calculate the pH of the solution.
b. Calculate the pOH of the solution.
c. Calculate the hydroxide ion concentration of the solution
Answer:
a.) pH = 3.62
b.) pOH = 10.38
c.) [OH⁻] = 4.17 x 10⁻¹¹
Explanation:
The hydronium ion concentration can be represented by the symbol: [H₃O⁺]. The hydroxide ion concentration can be represented by the symbol: [OH⁻].
a.) The pH of a solution represents the hydrogen (hydronium) ion concentration. It can be calculated using the following formula:
pH = -log[H₃O⁺]
Since you have been given the hydronium concentration, you can easily find the pH.
[H₃O⁺] = 2.4 x 10⁻⁴
pH = -log[2.4 x 10⁻⁴]
pH = 3.62
b.) The pOH of a solution represents the hydroxide concentration. It measures the opposite of the pH measurement. Since the pH range goes up to 14, you can find the pOH using the following formula:
pOH + pH = 14
Since you now know the value of the pH, you can plug it into the formula to find the pOH.
pOH + 3.62 = 14
pOH = 10.38
c.) You can find the hydroxide concentration using the following formula:
[OH⁻] = 10^-pOH
Since you now know the value of the pOH, you can plug it into the formula to find the hydroxide concentration.
[OH⁻] = 10⁻¹⁰°³⁸
[OH⁻] = 4.17 x 10⁻¹¹

Calculate the moles of FeCl3 that will form if 1.0 moles of each reactant mix together. 4. How many grams of FeCl3 that will form if 1.0 g of each reactant mix?
Answer:
1.) 2 Fe (s) + 3 Cl₂ (g) ---> 2 FeCl₃ (aq)
2.) 2.0 moles FeCl₃
3.) 0.67 moles FeCl₃
4.) 1.5 g FeCl₃
Explanation:
1.)
The unbalanced reaction:
Fe (s) + Cl₂ (g) ---> FeCl₃ (aq)
Reactants: 1 iron, 2 chlorine
Products: 1 iron, 3 chlorine
The balanced reaction:
2 Fe (s) + 3 Cl₂ (g) ---> 2 FeCl₃ (aq)
Reactants: 2 iron, 6 chlorine
Products: 2 iron, 6 chlorine
2.)
To find moles FeCl₃, you need to multiply the given value by the mole-to-mole ratio of Fe to FeCl₃. This ratio is constructed via the coefficients from the balanced equation.
2.0 moles Fe 2 moles FeCl₃
--------------------- x ------------------------ = 2.0 moles FeCl₃
2 moles Fe
3.)
To determine how much FeCl₃ is produced, you need to identify the limiting reagent. To find it, you need to convert both reactants to the product then identify which reactant gives you the smallest amount of product. This reactant is the limiting reagent and will give you your actual answer.

The greater, the ionic property, the greater will be solubility. water is a covalent compound where calcium carbonate is ionic that's why the solubility of [tex]CaCO_{3}[/tex](s) would be greater.
What is solubility?The capability of a substance, the solvent, to combine with another substance, the solvent, has been known as solubility. Insolubility, or just the solute's inability to create that kind of a solution, would be the opposite attribute.
How does solubility depend on the ionic compound?Ionic chemicals dissolve readily in just about any liquid that has the ability to rupture the ionic link present in them. Since water itself has a stronger ionic bond and is still polar in nature, water disrupts the ionic link by hydrogen bonding. Several other solvents, like kerosene and gasoline, are unable to dissolve the ionic bond.
The greater, the ionic property, the greater will be solubility. water is a covalent compound where calcium carbonate is ionic that's why the solubility of [tex]CaCO_{3}[/tex](s) would be greater in distilled water than in tap water that contains 50 mg/L of calcium ions

Explanation:
Thats the percent composition for each one in your question
Answer:
Hello! The answer to your question is:
Mg: 41.68%
O2: 54.86%
H2: 3.46%
Explanation:
We need to find the percent composition of each element, so first, we need to find the molar mass. This is calculated by using the number underneath the element. The "2" outside of the parentheses is distributed to Oxygen and Hydrogen as well-meaning that you multiply the number by 2:
Mg: 24.31 g/mol
O2: 16.00 × 2 = 32.00 g/mol
H2: 1.01 × 2 = 2.02 g/mol
Now, we have to add up the molar mass of each element:
24.31 g/mol + 32.00 g/mol + 2.02 g/mol = 58.33
To find the percent composition of each element, you have to divide the molar mass of each element by the total molar mass:
Mg: [tex]\frac{24.31 g/mol}{58.33 g/mol} \\= 41.68 percent[/tex]
O2: [tex]\frac{32.00 g/mol}{58.33 g/mol} \\= 54.86 percent[/tex]
H2: [tex]\frac{2.02 g/mol}{58.33 g/mol} \\= 3.46 percent[/tex]
The percent composition of each element is:
Mg: 41.68%
O2: 54.86%
H2: 3.46%
