Lead cannot melt at such level, hence it cannot break down into individual atoms or molecules. A change in the bonding of atoms or molecules is referred to as melting.

The metallic connections are broken and the atoms are made more mobile by the energy needed to melt the metal. Atoms have the same kinetic energy as they did as a solid at a particular temperature, such as the melting point.

No, an atom cannot be melted. The three common states of matter no longer hold true when you are dealing with so tiny a piece. Atoms do not alter until by nuclear fission or fusion.

a) 107.1 g of hydrosulfric acid can be formed.

b) Aluminium sulfide is the limiting reactant.

c) 378g of excess reactant remains.

d) 52.75 % is the percent yield.

The limiting reactant or limiting reagent is a reactant in a chemical reaction that determines the amount of product that is formed.

Identification of the limiting reactant can help calculate the theoretical yield of a reaction.

Given the reaction,

2Al₂S₃ + 6 H₂O = 2Al(OH)₃ + 3H₂S

Mass of aluminium sulfide = 316g

Mass of water = 493 g

Moles = Mass ÷ molar mass

Moles of Aluminium sulfide = 316 ÷ 150

=  2.10 moles

Moles of water = 493 ÷ 18

= 27.3 moles

Since moles of aluminium sulfide is less, it is the limiting reagent.

From the reaction, 2 moles of aluminium sulfide gives 3 moles of H₂S.

1 moles of Al₂S₃ will give 3 ÷ 2 moles of H₂S.

Thus, 2.1 moles of Al₂S₃ will give 1.5 × 2.1 moles

                                 = 3.15 moles of H₂S

Mass of H₂S = Moles × molar mass

                                  = 3.15 × 34 = 107.1 g

From the reaction, 2 moles of aluminium sulfide gives 6 moles of H₂O.

1 mole will need 3 moles of water.

Thus, 2.1 moles will need 3 × 2.1 moles = 6.3 moles of water

Excess of water = 27.3 - 6.3 = 21 moles

Mass of excess reactant = 21 × 18 = 378g

Actual yield of  H₂S = 203g

Theoretical yield = 107.1 g

% yield = (107.1 × 100) ÷ 203 = 52.75 %

Therefore,

a) 107.1 g of hydrosulfric acid can be formed.

b) Aluminium sulfide is the limiting reactant.

c) 378g of excess reactant remains.

d) 52.75 % is the percent yield.

Von Helmont think that plants get their nourishment from soil because he concluded an experiment and watered the plant after which he came to know that.

Plant growth is the ability of a plant to develop its roots in length, sets in length, and breadth in girth. Plant growth occurs in four phases. These stages are as follows...

Plant seeding, germination, and seedling formation all increase.

John Baptista van Helmont (1580-1644) contributed to the understanding of photosynthesis. He planted a willow tree in a measured amount of dirt. After five years, he observed that the willow tree weighted around 74 kg more than it did when he first planted it. Van Helmont decided that plant development could not be solely attributable to soil minerals because the weight of the soil had scarcely altered. He assumed that the increased plant material had come only from the water.

For the first time, this invalidated the Ancient Greeks' earlier idea that plants grew bulk by absorbing minerals from the earth. Van Helmont was the first to put this theory to the test and discover it to be false.

The mole fraction of ethanol in the solution is 0.1903, and the mole fraction of water in the solution is 0.8097.

To calculate the mole fraction of each component in the solution, we need to determine the number of moles of each component first.

The molar mass of ethanol (C2H5OH) is:

2(12.01 g/mol) + 6(1.01 g/mol) + 1(16.00 g/mol) = 46.07 g/mol

Number of moles of ethanol = mass/molar mass = 300 g / 46.07 g/mol = 6.5166 mol

The molar mass of water (H2O) is:

2(1.01 g/mol) + 1(16.00 g/mol) = 18.02 g/mol

The mole fraction of ethanol is:

moles of ethanol / total moles = 6.5166 mol / 34.2625 mol = 0.1903

The mole fraction of water is:

moles of water / total moles = 27.7459 mol / 34.2625 mol = 0.8097

Therefore, the mole fraction of ethanol in the solution is 0.1903, and the mole fraction of water in the solution is 0.8097.

The absorption of a free-moving neutron by the atom's nucleus is what causes the atom's nucleus to become unstable in nuclear fission reactions.

What is nuclear fission?

Nuclear fission is a process where the nucleus of an atom is split into two or more smaller nuclei, along with the release of a large amount of energy. This process typically occurs when a free neutron collides with the nucleus of a heavy atom, such as uranium-235 or plutonium-239. When the nucleus absorbs the neutron, it becomes highly unstable and splits apart into two or more smaller nuclei, which can then go on to collide with other nuclei and split apart in a chain reaction.

The energy released in the process of nuclear fission is used to generate electricity in nuclear power plants, and also has applications in nuclear weapons. However, the process also creates radioactive waste materials that must be carefully managed and disposed of due to their potential hazards to human health and the environment.

C. The absorption of a free-moving neutron by the atom's nucleus is what causes the atom's nucleus to become unstable in nuclear fission reactions.

When a neutron is absorbed by the nucleus, it can cause the nucleus to become so unstable that it splits apart into two smaller nuclei and releases additional neutrons and energy in the process. This chain reaction of nuclear fission can be controlled and harnessed for use in nuclear power plants.

The statements which is supported by the information in the graph is, The use of fluorinated gases has contributed to global warming.

How does fluorinated gases contributes to global warming?

Fluorinated gases, also known as F-gases, are a group of man-made gases that are commonly used in various industrial and commercial applications, such as refrigeration and air conditioning systems, electrical equipment, and aerosol sprays. They are made up of compounds such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).

F-gases are potent greenhouse gases, meaning they have a high global warming potential (GWP), which is a measure of their ability to trap heat in the atmosphere. For example, HFCs have a GWP that is thousands of times greater than that of carbon dioxide (CO2).

When F-gases are released into the atmosphere, they contribute to global warming by trapping heat and preventing it from escaping into space. This effect, known as the greenhouse effect, causes the Earth's temperature to rise and leads to climate change.

In addition to their direct impact on global warming, F-gases can also indirectly contribute to climate change by promoting the use of energy-intensive technologies, such as air conditioning and refrigeration systems. The increased demand for energy can lead to the burning of fossil fuels, which further increases greenhouse gas emissions and exacerbates global warming.

C. It must have a full or partial charge.

When a particle dissolves in water, it becomes surrounded by water molecules. The polarity of water molecules allows them to interact with other polar molecules, including ions or molecules that have a full or partial charge.

These interactions between the charged particle and water molecules help to break apart the intermolecular forces holding the particle together and allow it to dissolve in water.

Particles that lack a full or partial charge, such as those with nonpolar covalent bonds or areas of neutral charge, typically do not dissolve well in water.

Each trophic level represents a transfer of energy, with only about 10% of the energy being transferred from one level to the next.

What is Energy ?

Energy is a fundamental concept in physics and refers to the ability of a system to perform work. It is a property of objects and substances that can be transferred to other objects or converted into different forms, but it cannot be created or destroyed. There are different forms of energy, such as kinetic energy (the energy of motion), potential energy (the energy stored in an object due to its position or shape), thermal energy (the energy associated with the temperature of an object), electrical energy (the energy associated with the movement of charged particles), and many others. Energy plays a crucial role in many natural processes and is essential for life and human activities.

Higher amounts of energy flow through trophic levels, which are known as food chains. In a food chain, energy is transferred from one organism to another as they eat each other. The first trophic level consists of primary producers, such as plants, which convert solar energy into chemical energy through photosynthesis. The second trophic level consists of herbivores, which consume the primary producers. The third trophic level consists of carnivores, which consume the herbivores.
