Biological and non-biological methods of metal extraction refer to the different ways in which metals can be extracted from ore deposits in the ground. Biological methods, also known as biomining, use microorganisms to extract metals from ores. These microorganisms, such as bacteria and fungi, can break down the chemical bonds in ores and release the metals they contain, which can then be extracted and purified. Non-biological methods, on the other hand, use physical or chemical processes to extract metals from ores. These methods can include roasting, smelting, and leaching, and they do not require the use of living organisms.
One key difference between biological and non-biological methods of metal extraction is the speed at which they can extract metals. Biological methods are generally slower than non-biological methods, but they are also often more environmentally friendly, as they do not produce as much waste or pollution. Non-biological methods, on the other hand, can be faster and more efficient, but they can also be more harmful to the environment.
Another difference between the two types of metal extraction methods is the types of ores that they can be used on. Biological methods are typically more effective on sulfide ores, which are ores that contain sulfur. Non-biological methods, on the other hand, are often more effective on oxide ores, which are ores that contain oxygen.
Overall, biological and non-biological methods of metal extraction are two different approaches to extracting metals from ores. While both methods have their advantages and disadvantages, they are both important tools in the field of mining and metallurgy.
a sample of 2.0 moles of hydrogen gas is placed in a container with a volume of 10.4 l. what is the pressure of the gas in torr if the gas is at 25oc?
Pressure of the gas in torr is 3575.77 when 2.0 moles of hydrogen gas are present in a container of 10.4 L at room temperature.
What is pressure in terms of gas ?
The average linear momentum of a gas's moving molecules is then calculated as the gas's pressure. Gases produce pressure, or force per unit of area. In addition to torr, atmosphere, and bar, the pressure of a gas can also be stated in many additional SI units, such as pascal or kilopascal.
Given :
Moles of hydrogen = 2.0 moles
volume of container = 10.4 L
Temperature = 25° C
Using the gas law
PV = nRT
P x 10.4 L = 2.0 moles x 0.0821 atm L/ mol k
P= 4.70 atm
P = 4.70 atm x 760 torr/ atm
P = 3575.77 torr
Thus pressure of the gas in torr is 3575.77 when 2.0 moles of hydrogen gas are present in a container of 10.4 L.

thermodynamically, at a given temperature, an oxide is more stable with respect to metal and oxygen gas at higher partial pressure of oxygen than lower partial pressure of oxygen: true or false? g
It is true that an oxide is thermodynamically more stable with respect to metal and oxygen gas at greater partial pressures of oxygen than at lower partial pressures of oxygen at a given temperature.
When a pure metal is oxidized at a high temperature, one or more oxides may occur. Oxidation is prevented if the partial pressure of oxygen is less than the equilibrium value. On the other hand, that metal will be reduced for an oxygen partial pressure that is lower than the equilibrium value at a specific temperature. The Ellingham diagram is used in metallurgy to forecast the temperature at which a metal, its oxide, and oxygen are at their equilibrium. A metal is oxidized if the atmospheric oxygen partial pressure is higher than the dissociation pressure, and it is reduced to a metal if it is lower than the dissociation pressure.

predict whether, to any significant extent, ag(s) will react with 1 m hcl(aq).
Under normal conditions, Ag does not react with hydrochloric acid. However, if the HCl is concentrated and heated, it can dissolve silver to form silver chloride.
To determine whether Ag(s) will react with 1 M HCl(aq), we can consult a table of standard reduction potentials to see if the reaction is thermodynamically favorable. If the standard reduction potential for the reaction Ag(s) + [tex]H^+[/tex] (aq) -> [tex]Ag^+[/tex] + H(aq) is positive, then the reaction is not thermodynamically favorable and will not occur to a significant extent. If the standard reduction potential for the reaction is negative, then the reaction is thermodynamically favorable and will likely occur to a significant extent.
Alternatively, you can also perform a simple experiment to see if the reaction occurs. Simply mix a sample of Ag(s) with 1 M HCl(aq) and observe if any reaction occurs. If the solution becomes cloudy or if the silver metal appears to dissolve or change color, then a reaction has occurred.

As the first five elements in group 14 are considered in order from top to bottom, there are changes in both the electronegativity values and atomic radii changes.
The columns of the periodic table that contain elements with the same number of valence electrons are referred to as groups. The atomic size of the elements grows as one moves from top to bottom in the 14th group of the periodic table, while electronegativity drops. All elements will have an equal number of electrons in their initial shell and their outermost shell. Thus, changes in atomic radii and electronegativity levels.
Further, The group 14 elements exhibit the periodic table's broadest variation of the chemical behaviour of any group. In general, the electronegativity falls as we advance down the group. Ionization energies drop as atomic radii rise within the group. Down the group, the metallic characteristics also get stronger.

What is the difference between the collision theory and the transition state theory? How do they explain the factors that affect the rate of a chemical reaction?
The basic differences between the collision theory and the transition state theory are-
Collision theory assumes a collision between reactants needs to happen before a reaction can take place. But on the other hand, during a reaction, an increase in potential energy corresponds to an energy barrier over which the reactant molecules must pass if the reaction is to proceed.The majority of collisions do not lead to a reaction, but only those in which the colliding species have: kinetic energy greater than a certain minimum called the activation energy, Ea, and the correct special orientation with respect to each other. Whereas the transition state occurs at the maximum of this energy barrier.Collision theory states that chemical reactions (in the gas phase) occur due to collisions between reactants. But transition state theory states that chemical reactions occur via going through a transition state.According to collision theory, chemical reactions occur only due to successful collisions. Although according to transition state theory, a chemical reaction will happen if and only if the reactants can overcome the activation energy barrier.The factors that affect the rate of a chemical reaction:
Temperature: With increasing temperature reaction rate will also increase.Concentration: In a solution, if the amount of reactants increases then the reaction rate increases.Pressure: Increasing pressure increases reaction rate.State of matter: Gases react more readily than liquids, whereas liquids react more readily than solids.Catalysts: A catalyst lowers the activation energy, then the reaction rate increases.Mixing: Mixing reactants improves reaction rate.To learn more about this topic,

in a metallic substance, electrons are shared among all of the metal atoms in the sample. how does this explain why metals are more malleable and ductile than ionic and covalent compounds?
Answer:
In a metallic substance, electrons are shared among all of the metal atoms in the sample, forming a "sea" of electrons that surrounds the metal ions. This electron sea is responsible for many of the unique properties of metals, including their high conductivity, malleability, and ductility.
The electron sea in a metallic substance allows the metal ions to slide past one another easily, making it easier to deform the metal without breaking it. In contrast, ionic and covalent compounds are held together by strong chemical bonds, which makes it more difficult to deform these materials without breaking the bonds. This is why metals are generally more malleable and ductile than ionic and covalent compounds.
