Is this an alpha or beta decay?

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.

[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.

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.

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.

Answer:

[tex]\Delta H=-92.7kJ[/tex]

Explanation:

Hello there!

In this case, according to the given information, we can infer that 890 kJ of energy are released when 1 mole of methane is burned; however, to find the total heat when 1.67 grams are burned, we first need to calculate the moles in this mass of methane:

[tex]1.67gCH_4*\frac{1molCH_4}{16.04gCH_4}=0.104molCH_4[/tex]

And thus, for calculating the resulting ∆H, we proceed as follows:

[tex]\Delta H=-890kJ/mol*0.104mol\\\\\Delta H=-92.7kJ[/tex]

La gravedad es una fuerza que actúa a distancia. La fuerza que actúa entre la tierra y los cuerpos en ella es la fuerza gravitacional.

Es un ejemplo típico de una fuerza de acción a distancia.

Por lo tanto, la fuerza tat que existe entre la tierra y los cuerpos que se encuentran en ella es una fuerza de distancia.

To calculate the work that an object does when it moves covering a distance of 3000 meters when it is propelled by a force of 65 Newton, one of the principles of mechanics must be considered.

A force does work when there is a displacement of the center of mass of the body on which the force is applied, in the direction of said force.

The work of the force on that body will be equivalent to the energy necessary to displace it, so that:

W = F.d

Substituting the corresponding values in said formula:

F = 65N

d = 3000m

W = 65 N. 3000 m

W = 195000 W

Answer:

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

Explanation:

In an alpha emission, an alpha particle is ejected from a large nucleus. An alpha particle is simply a helium nucleus (atomic number is 2 and mass number is 4) so that means that the atomic number of the emitting nucleus decreases by 2 and its mass number decreases by 4.
