Using the rxn below determine the following: What is the limiting reagent, theoretical yield of nitic oxide, and how many grams of excess reagent remain when producing nitric oxide when using 4.65g of ammonia to react with 4.25g of oxygen?

Atoms are the unit of the molecule of the compound. The 3.01 x 10²⁴  atoms of oxygen are present in 5 moles of water and 3 moles of carbon dioxide in the sample.

Atoms are the smallest fundamental unit of the compounds that can be given by Avogadro's number.

For calculating the oxygen atoms in 5 mole water:

If 1 mole = 6.02 × 10²³

Then, 5 moles = 5 ×  6.02 × 10²³

Hence, 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water.

Moles of carbon dioxide in the sample is calculated as:

If 1 mole of carbon dioxide = 6.02 × 10²³ molecules

Then moles in 1.8 x 10²⁴ molecules will be,

(1.8 x 10²⁴ molecules) ÷ (6.02 × 10²³ molecules)  = 3 moles

Hence, 3 moles of carbon dioxide is present in the sample.

The molarity of the solution of H₃PO₄ needed to neutralize the KOH solution is 0.35 M

H₃PO₄ + 3KOH —> K₃PO₄ + 3H₂O

From the balanced equation above,

MaVa / MbVb = nA / nB

(Ma × 10.2) / (0.2 × 53.5) = 1 / 3

(Ma × 10.2) / 10.7 = 1 / 3

Cross multiply

Ma × 10.2 × 3 = 10.7

Ma × 30.6 = 10.7

Divide both side by 30.6

Ma = 10.7 / 30.6

The answer is 125 ml air bubbles come out from under the glass

Charles's Law describes the directly proportional relationship between the volume and temperature (in Kelvin) of a fixed amount of gas, when the pressure is held constant.

V∝T

or express from two volume/temperature points:

[tex]\rm\dfrac{V_{1}}{T_{1}} =\dfrac{V_{2}}{T_{2}}[/tex]

This equation can be used to solve for initial or final value of volume or temperature

under the given condition that pressure and the number of mole of the gas stay the same.

It is given that

V₁ = 500 ml  

T₁= 7 + 273 = 280 K

T₂ = 77+273 = 350 K

​V₂= ?

Substituting the values in the above in the above equation

[tex]\rm\dfrac{500}{280}} =\dfrac{V_{2}}{350}[/tex]

​V₂ =  625 ML

The volume of the glass is still 500 ml,

so, the volume of bubbles is 125 ml.

The pressure of the given moles of propane with the given volume and temperature is 1.024atm.

The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.

It is expressed as;

PV = nRT

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )

Given the data in the question;

PV = nRT

P = nRT / V

P = ( 13mol × 0.08206Latm/molK × 288K ) / 300L

P = 307.23264Latm / 300L

P = 1.024atm

Therefore, the pressure of the given moles of propane with the given volume and temperature is 1.024atm.

Using the ideal gas equation and Gay Lussac's law, the volume of the passenger's collapsed bottle after landing is 0.0075 L.

The ideal gas equation shows the relationship between temperature, pressure, volume and number of moles.

The volume of the passenger's collapsed bottle after landing is 0.0075 L.

Given that;

PV = nRT

n = PV/RT

Hence:

P = 0.75 atm;

V = 0.5 L;

T = 295 K;

R = 0.082 atmL/K.mol

n = 0.75 * 0.5 / 0.082 * 295

n = 0.015 moles

If the pressure after landing was 1.0 atm;

V1n1 = V2n2

V2= V1n1/n2

V2 = 0.5 L *  0.015 moles/ 1 mole

V2 = 0.0075 L

The volume of the passenger's collapsed bottle after landing is 0.0075 L.

A combustion reaction is a reaction that reacts with oxygen to produce the product. 3.5 moles of methane release - 3115 kJ/mol of heat.  

A combustion reaction is a chemical reaction that involves the burning of the reactant in the presence of the oxygen molecule to release heat.

The balanced reaction of methane combustion is given as:

CH₄(g) + 2O₂ (g) → CO₂(g) + 2H₂O (l), ΔH = -890 kJ/mol

From the reaction, it can be said that 1 mole of methane combusts to produce -890kJ/mol enthalpy.

So, 3.5 moles will produce, 3.5 × -890kJ/mol = - 3115 kJ/mol.
