Here is the reaction:

3 NO2 (g) + H2O (l) = 2HNO3 (l) + NO (g)

Id Appreciate The Help! :)Here Is The Reaction:3 NO2 (g) + H2O (l) = 2HNO3 (l) + NO (g)

Answers

Answer 1

Answer: 300g

Explanation:

first we write the given values on top

224L. x

3 NO2 (g) + H2O (l) = 2HNO3 (l) + NO (g)

22.4L 30g

then we form a formula

224L/22.4L= x/30g

224*30/22.4

6720/22.4= 300g

Answers

Answer:

Radioactive decay refers to the release of radiation from the nuclei.

Explanation:

Radioactive decay also known as nuclear decay is a type of process in which an unstable atomic nucleus loses energy by radiation. Alpha decay, beta decay, and gamma decay are the three of the most common types of decay, which emitting one or more particles or photons from the unstable nuclei of radioactive atom. Beta decay occurs due to weak force, while the alpha and gamma decay happens due to electromagnetic and strong forces.

A container of oxygen gas is at STP. If this sample is put into an oven at 280 C, what would its pressure be, in atmospheres?

Answers

Explanation:

Step 1:

Data obtained from the question. This include the following:

Initial pressure (P1) = 1atm

Initial temperature (T1) = 0°C = 0°C + 273 = 273K

Final temperature (T2) = 280°C = 280°C + 273 = 553K

Final pressure (P2) =...?

Step 2:

Determination of the new pressure of the gas.

Since the volume of the gas is constant, the following equation:

P1/T1 = P2/T2

will be used to obtain the pressure. This is illustrated below:

P1/T1 = P2/T2

1/273 = P2 / 553

Cross multiply

273x P2 = 553

Divide both side by 273

P2 = 553/273

P2 = 2.03atm

Therefore, the new pressure of the gas will be 2.03atm

Answer:

[tex]\boxed {\boxed {\sf P_2=2.03 \ atm}}[/tex]

Explanation:

We are concerned with the variables of temperature and pressure, so we use Gay-Lussac's Law, which states the temperature of a gas is directly proportional to the pressure. The formula is:

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

We know that the container of gas begins at standard temperature and pressure (STP). This is 1 atmosphere of pressure and 273 Kelvin.

[tex]\frac { 1 \ atm}{ 273 \ K} = \frac{P_2}{T_2}[/tex]

We know the gas is put into an oven at 280 degrees Celsius. We can convert this to Kelvin.

K= °C + 273.15 K= 280 +273.15K= 553.15

[tex]\frac { 1 \ atm}{ 273 \ K} = \frac{P_2}{553.15 \ K}[/tex]

We are solving for the new pressure, so we must isolate the variable P₂. It is being divided by 553.15 Kelvin. The inverse of division is multiplication, so we multiply both sides by 553.15 K

[tex]553.15 \ K *\frac { 1 \ atm}{ 273 \ K} = \frac{P_2}{553.15 \ K} * 553.15 \ K[/tex]

[tex]553.15 \ K *\frac { 1 \ atm}{ 273 \ K}= P_2[/tex]

The units of Kelvin cancel.

[tex]553.15 *\frac { 1 \ atm}{ 273 }= P_2[/tex]

[tex]2.02619047619 \ atm = P_2[/tex]

Rounded to the nearest hundredth:

[tex]2.03 \ atm \approx P_2[/tex]

The new pressure is approximately 2.03 atmospheres.

a gas with a volume of 20.0l at a pressure of 275 kpa is allowed to expand to a volume of 35.0l. what is the pressure in the container if the temperature remains constant?

1. 2.54 kPa

2. 157 kPa

3. 481 kPa

pls help ;(

Answers

Answer:

[tex]\boxed {\boxed {\sf 2. \ 157 \ kPa}}[/tex]

Explanation:

Since temperature remains constant, the only variables that change are volume and pressure. Therefore, we are using Boyle's Law. This states that the pressure is inversely proportional to the volume. The formula is:

[tex]P_1V_1=P_2V_2[/tex]

We know the gas starts with a volume of 20.0 liters at a pressure of 275 kPa. We can substitute these values into the left side of the formula.

[tex]275 \ kPa *20.0 \ L=P_2V_2[/tex]

We know the gas expands to a volume of 35.0 Liters, but we do not know the pressure.

[tex]275 \ kPa *20.0 \ L=P_2* 35.0 \ L[/tex]

Since we are solving for the new pressure, we must isolate the variable P₂. It is being multiplied by 35.0 Liters and the inverse of multiplication is division. Divide both sides by 35.0 L.

[tex]\frac {275 \ kPa * 20.0 \ L}{ 35.0 \ L}= \frac{P_2*35.0 \ L}{35.0 \ L}[/tex]

[tex]\frac {275 \ kPa * 20.0 \ L}{ 35.0 \ L}=P_2[/tex]

The units of liters cancel.

[tex]\frac {275 \ kPa * 20.0 }{ 35.0 }=P_2[/tex]

[tex]\frac {5500}{35.0} \ kPa= P_2[/tex]

[tex]157.142857 \ kPa=P_2[/tex]

The original measurements of pressure and volume have 3 significant figures, so our answer must have the same. For the number we calculated, that is the ones place.

The 1 in the tenths place (157.142857) tells us to leave the 7 in the ones place.

[tex]157 \ kPa= P_2[/tex]

If the gas expanded to a volume of 35.0 liters while the temperature remained constant, the pressure in container was approximately 157 kilopascals.

Tritium (hydrogen-3) has a half-life of 12.3 years. How old is a bottle of wine if the tritium content is determined to be 25% in new bottle of wine

Answers

Answer:

24.6 years

Explanation:

Applying,

A = (A')[tex]2^{a/n}[/tex]..................... Equation 1

Where A = Original Tritium content in the wine, A' = Tritium content in the wine after decay, a = age of the old bottle, n = half life of Tritium

From the question,

Let A = X, therefore, A' = 0.25X

Given: n = 12.3 years

Substitute these values into equation 1

X = 0.25X([tex]2^{a/n}[/tex])

1 = 0.25×([tex]2^{a/12.3}[/tex])

1/0.25 =

4 = [tex]2^{a/12.3}[/tex]

[tex]2^{a/12.3}[/tex] = 2²

Equation the base,

a/12.3 = 2

a = 12.3×2

a = 24.6 years

An alpha particle emission causes the atomic number of a nuclide to decrease by 2 and its mass number to decrease by 4.

What is nuclear emission?

Nuclear Emission explains the release of energy stored in the nucleus of an atom in the form of particles like alpha particles, beta particles, gamma ray etc.

When a nucleus emits an alpha particle, it loses 2 protons and 2 neutrons, so its atomic number decreases by 2 and its mass number decreases by 4.

Anthony needs to make a solution with a concentration of 2.5m. He begins with 2.0 iters and a 8.0M solution. What final volume does he need. Tally and solve.

Answers

Answer:

The final volume is 6.4 L.

Explanation:

Dilution is reducing the concentration of a chemical and is achieved by adding more solvent to the same amount of solute. In other words, dilution is the procedure that is followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding more solvent.

In a dilution the amount of solute does not vary, and as only more volume (and mass) of solvent is being added, the concentration of the solute decreases.

In a dilution the expression is used:

Ci*Vi = Cf*Vf

where:

Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volume

In this case:

Ci: 8 M Vi: 2 L Cf: 2.5 M Vf: ?

Replacing:

8 M* 2 L= 2.5 M* Vf

Solving:

[tex]Vf=\frac{8 M* 2 L}{2.5 M}[/tex]

Vf=6.4 L

The final volume is 6.4 L.

08.04 MC) An unknown solution has a pH of 7.2. Which of these chemicals is likely to cause the greatest decrease in the pH of the solution when added to the solution? (5 points) a HF b KOH c NH3 d HNO3

Answers

Answer:

HNO3

Explanation:

i have the test

The correct answer that will decrease the PH is ( HNO3)

Since the unknown solution is containing a pH of 7.2, it means it is more basic not acidic, then to make it have  decrease in PH, then acidic substance needs to be added to it so as to reduce the PH from 7.2

KOH : potassium hydroxide is a base, if it is added to the substance, it will increase in PH value

NH3 : Ammonia is a base, if it is added to the substance, it will increase in PH value

HNO3 : Trioxonitrate (v) acid is an acid , adding it to the substance will make the PH to be acidic hence decrease in PH

When a substance  is neither acidic nor basic it can be regarded as   neutral.

The pH scale gives the measurements of  how acidic or basic a particular substance is.

The pH scale can be given in the  ranges starting from 0 to 14.

A pH of 7 is  considered neutral.

Therefore, decrease in PH can be achieved by adding acidic substance.

ΔU for a van der Waals gas increases by 475 J in an expansion process, and the magnitude of w is 93.0 J.

Answers

Complete question:

ΔU for a van der Waals gas increases by 475 J in an expansion process, and the magnitude of w is 93.0 J. calculate the magnitude of q for the process.

Answer:

The magnitude of q for the process 568 J.

Explanation:

Given;

change in internal energy of the gas, ΔU = 475 J

work done by the gas, w = 93 J

heat added to the system, = q

During gas expansion process, heat is added to the gas.

Apply the first law of thermodynamic to determine the magnitude of heat added to the gas.

ΔU = q - w

q = ΔU +  w

q = 475 J  +  93 J

q = 568 J

Therefore, the magnitude of q for the process 568 J.
