How much energy is released if a sample loses 0.025 kg mass through
radioactive decay?

Answer:

ok

Explanation:

Answer:

No, although the bean crop can grow perfectly in full sun or a little shade in very warm places. It does not mean that they will adopt the growth patterns of the cactus, especially because this plant needs constant watering (in small quantities), very constant. Beans require good drainage for their growth.

Each vegetation have its own characteristics and the power of adaptation. A green bean cannot survive in a desert like a cactus in desert without water. It can only grow thick in soil with proper water content and nutrients.

Cactus is a type of plant grow in dry regions such as deserts. It can adapt in deserts without water for long time because, the plant have enough water storage in its stem.

Domestic vegetation such as bean, pea, nuts etc ill not grow in dry regions because they cannot adapt in deserts without water. The soil in deserts is dry and have no nutrients.

These conditions prevent the growth of vegetables in desert areas. Moreover, desert have summer season only. The extreme temperature over there will cause the normal plants to diminish.

Therefore, planting green bean in deserts will not make it grow thick like a cactus plant.

The only cosmic object known to contain life is Earth, which would be located third from the Sun. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water. The oceans cover over 71% of Earth's crust, dwarfing its polar ice, lakes, including rivers.

The sole natural satellite of Earth would be the Moon. It makes up the Earth-Moon satellite system with Earth. Its diameter is equivalent to one-fourth of Earth. It should be the biggest satellite of a planet compared to the main, bigger than any existing dwarf planet, as well as the fifth biggest satellite in the Planetary System.

Answer:organelle 1

Explanation:

Organulo 1 is the organelle that  stores the information that determines an individual blood type. The correct option is option A.

A tiny cellular component known as an organelle serves a specialised purpose within a cell. The cytoplasm of prokaryotic and eukaryotic cells contains organelles. Organelles are frequently encased by a separate membrane in eukaryotic cells because they are more complicated.

Similar to the internal organs of the body, organelles are specialised and carry out important tasks required for proper cellular function. Organelles are responsible for a variety of tasks, such as powering a cell's energy needs and regulating its development and reproduction. Organulo 1 is the organelle that  stores the information that determines an individual blood type.

Therefore, Organulo 1 is the organelle that  stores the information that determines an individual blood type. The correct option is option A.

Answer:

[tex]\Rightarrow V_2 = 389mL[/tex]

Explanation:

To solve this question, we could use Charles' law since both the number of mole and pressure are constant

At STP pressure P = 760 tor and Temperature = 273K

V1 =425mL, T1 =298K and T2 =273K

and [tex]\frac{V_1}{T_1} =\frac{V_2}{T_2}[/tex]

[tex]\Rightarrow V_2 =T_2\times\frac{V_1}{T_1}[/tex]

[tex]\Rightarrow V_2 =273\times\frac{425}{298}[/tex]

Therefore, [tex]\Rightarrow V_2 = 389mL[/tex]

Answer:

115 mL of a gas is at 45.8 kPa and 57.2°C. What is the volume of the gas at 99.3 kPa and 112.3°C?[5] 11. ... What is the pressure of 62.76 g of carbon dioxide (CO2) gas if it occupies a volume of 35,000 mL at standard temperature?

Explanation:

By using gas law , the volume will be 61.9 mL .

According to the gas law, the pressure of a gas generally directly proportional to its temperature at a fixed volume.

Gas law can be represented as:

[tex]P_{1} V_{1}/ T_{1} = P_{2} V_{2} / T_{2}[/tex]

Calculation of volume with the aid of gas law:

It is given that, [tex]P_{1}[/tex] = 45.8 kPa, [tex]P_{2}[/tex] = 99.3 kPa , [tex]T_{1}[/tex] = 57.2°C, [tex]T_{2}[/tex] = 112.3°C, [tex]V_{1}[/tex] = 115 mL .

Now, put the values of given data in gas laws equation.

(45.8kPa)(115mL)/(330K)= (99.3kPa)([tex]V_{2}[/tex])(385.3K)

[tex]V_{2}[/tex] = 61.9 mL

Therefore, the volume will be 61.9 mL .

5.6 atm is  the partial pressure of the rest of the gases in the container other than the oxygen.

Each gas in a mixture adds to the overall pressure of a mixture. This portion represents the pressure. The pressure a gas would have if it were in its own volume and at its own temperature is known as the partial pressure. According to Dalton's law, the pressure distribution of an ideal gas mixture is equal to the combined partial pressures of the component gases.

The study of partial pressure is significant in the domains of physics, chemistry, and biology. The partial pressure of oxygen or carbon dioxide in the blood is used to calculate blood levels of each substance. The overall pressure in a container is equal to the sum of the partial pressures. The remaining gases must make up the remaining 5.6 atm if the oxygen partial pressure equals 4.2 atm and the sun reaches 9.8 atm in pressure.

Therefore, 5.6 atm is  the partial pressure of the rest of the gases in the container other than the oxygen.

Answer: The volume of given ball is 21 L.

Explanation:

Given : Pressure = 1.0 atm,      no. of moles = 0.85 mol

Temperature = [tex]25^{o}C = (25 + 273) K = 298 K[/tex]

According to the ideal gas equation, formula used is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

[tex]PV = nRT\\1.0 atm \times V = 0.85 mol \times 0.0821 Latm/mol K \times 298 K\\V = 21 L[/tex]

Thus, we can conclude that the volume is 21 L.

He  represents an alpha particle and the correct option is option B.

Alpha particles are alternatively known as Alpha radiation or Alpha rays. It is a positively charged particle emitted from the decay of various radioactive materials.

They are emitted from the nucleus of some radionuclides during a form of radioactive decay, called alpha-decay.

Alpha particle mass is due to the two protons and two neutrons bonding.

An alpha-particle is identical to the nucleus of a normal (atomic mass four) helium atom i.e. a doubly ionised helium atom.

Therefore, He  represents an alpha particle and the correct option is option B.
