According to the stoichiometry of the mentioned chemical equation, 17.77 g of nitrogen gas is formed.

What is stoichiometry?

It is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.

64 g of ammonium nitrite gives 36 g of nitrogen , thus, 32.5 g of ammonium nitrite will give 32.5 ×36/64=17.77 g.

Thus,17.77 g of nitrogen gas is formed.

One atomic mass unit has a mass of 1.6605 × 10−24 g. What is the mass of one atom of sodium?

Answers

Answer:

one atom of sodium has a mass of approximately 37.9968 x 10^-24 grams.

Explanation:

The atomic mass of sodium is approximately 22.99 atomic mass units. To convert from atomic mass units to grams, we multiply by the conversion factor of 1.6605 x 10^-24 g/atomic mass unit:

mass (g) = 22.99 atomic mass units * (1.6605 x 10^-24 g/atomic mass unit) = 37.9968 x 10^-24 g

So one atom of sodium has a mass of approximately 37.9968 x 10^-24 grams.

What is the mass percent of water in IrBr₃・4 H₂O?

Answers

The mass percent of water in IrBr₃・4 H₂O is  14.4%.

How to calculate mass percent?

To find the mass percent of water in  IrBr₃・4 H₂O, first determine the mass of water present in the compound and then divide it by the total mass of the compound and multiply by 100 to express the answer as a percentage.

Let's assume that the molecular weight of IrBr3•4 H2O is 500 g/mol. In that case, the mass of water present in the compound would be 4 x 18 g/mol (the molecular weight of water) = 72 g. The total mass of the compound is 500 g, so the mass percent of water in  IrBr₃・4 H₂O can be calculated as follows:

(72 g / 500 g) x 100 = 14.4%

So, the mass percent of water in IrBr₃・4 H₂O is 14.4%.

How many liters would you need to make a 1 m solution if you have 6 mol of sodium hydroxide.

Answers

The liters would we need to make the 1 M solution if we have 6 mol of sodium hydroxide of 6 L.

The moles of the sodium hydroxide = 6 mol

The molarity of the sodium hydroxide = 1 M

The expression for the molarity is as follows :

The molarity = moles / volume in L

The volume of the sodium hydroxide = moles / molarity

The volume of the sodium hydroxide = 6 / 1

The volume of the sodium hydroxide = 6 L.

Thus the volume of the sodium hydroxide is 6L in the 1 M of the solution.

How many moles of gas would it take to fill an average man's lungs, total capacity of which is about 4.5 L. Assume 1.00 atm pressure and 37 degrees C

Answers

Answer:

0.0144 moles

Explanation:

To calculate the number of moles of gas in a volume of 4.5 liters, we use the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

First, we need to convert the temperature to Kelvin:

37°C = 37 + 273.15 = 310.15 K

Next, we can plug in the known values into the ideal gas law and solve for n:

PV = nRT

(1.00 atm)(4.5 L) = (n)(0.0821 Latm/mol K)(310.15 K)

n = (1.00 atm)(4.5 L) / [(0.0821 Latm/mol K)(310.15 K)] = 0.0144 moles

So, it would take approximately 0.0144 moles of gas to fill an average man's lungs.


ALLLEN

Answer:

0.124 moles

Explanation:

PV = nRT, can be used, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature in Kelvin.

Converting the volume to liters and temperature to Kelvin:

V = 45 L

T = 37°C + 273.15 = 310.15 K

Plugging these values into the ideal gas law:

1.00 atm * 45 L = n * 0.0821 Latm/mol/K * 310.15 K

Solving for n:

n = (1.00 atm * 45 L) / (0.0821 Latm/mol/K * 310.15 K) = 0.124 mol

So, it would take about 0.124 moles of gas to fill an average man's lungs.

___________ atm (2 sig figs)

Answers

The partial pressure of the remaining air is 0.94 atm.

Solving for the  of the remaining air, we have:

First, we'll convert the partial pressure of hydrogen sulfide from mmHg to kPa:

015.2 mmHg * (101.325 kPa / 760 mmHg)

= 0.020 kPa

Next, we'll find the sum of the partial pressures of carbon dioxide and hydrogen sulfide:

5.065 kPa + 0.020 kPa

= 5.085 kPa

Now we'll convert this sum to atmospheres:

5.085 kPa * (1 atm / 101.325 kPa)

= 0.05 atm

Finally, we'll subtract this sum from the total gas pressure to find the partial pressure of the remaining air:

0.99 atm - 0.05 atm

= 0.94 atm

So the partial pressure of the remaining air is 0.94 atm (to 2 sig figs).

The bond dissociation energy of 1 eV is roughly 96.485 kJ/mol. To break all the bonds in one mole of molecules (6.023 x [tex]10^{23}[/tex] molecules), we would need to multiply the bond dissociation energy by Avogadro's number:

Bond dissociation energy is the amount of energy necessary to break a chemical connection between two atoms. It is also known as bond energy or bond enthalpy.
