    The acidity of a terminal alkyne is due to the high level of s character in the sp hybrid orbital , which bonds with s orbitals of the hydrogen atom to form a covalent bond . The high level of S character in an sp hybridilized carbon cause the overlap region of the sigma bond to shift much closer to the carbon atom .

    It is a member of the halogen group. The element, No. 117 on the Periodic Table of Elements, had previously been designated ununseptium, a placeholder name that means one-one-seven in Latin. In November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name tennessine for element 117

    Answer - PX2 Element 'P' with atomic number 56 will lose two electrons to form P^ 2+ ion with 54 electrons corresponding to the stable noble gas electronic configuration. Halogen gains one electron to formX^-1 ion. One P^2+ ion combines with two X^-1 ions to formPX2 . Note: In a neutral molecule, the total charge on cations is numerically equal to the total charge on anions.

    The electron affinity for oxygen is lowest. As we move from left to right in a period, electron affinity becomes more negative. Argon (a noble gas) has large positive value for electron affinity.

    The inert pair effect is defined as the tendency of electrons in the outermost atomic s orbital to remain unionized or unshared in compounds of post-transition metals. ... When we say that electrons are inert, we essentially mean that they are spin paired. An example is in helium, with two electrons.

    The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound. Oxidation states are typically represented by integers which may be positive, zero, or negative. In some cases, the average oxidation state of an element is a fraction, such as 8/3 for iron in magnetic (Fe3O4 ).

    • The First law of thermodynamics is same as law of conservation of energy.
    • According to law of energy conservation: - Energy can neither be created nor be destroyed, only transformed to other forms.
    • According to first law of thermodynamics:- The change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings.
    • Examples:- Consider a ball falling from the roof of the building when at top of the building the ball has only potential energy and when it starts falling potential energy decreases and kinetic energy starts increasing. At the ground it has only kinetic energy.

    1st law of thermodynamics is also called law of conservation of energy. According to this law energy may change from one form to other but total energy of system will remain constant .. Hope this answer is helpful to u ???

    to derive the Ideal Gas Law, but the simplest way is to use the three simple gas laws. AVOGADRO'S LAW states the volume of a gas is directly proportional to the number of moles. V ∝ n BOYLE'S LAW states that the volume of a gas is inversely proportional to its pressure. V ∝ 1/P CHARLES'S LAW states that the volume of a gas is directly proportional to its Kelvin temperature. V ∝ T If we combine these laws, we get V ∝ nT/P We covert the proportionality to an equality V = knT/P We replace k with the universal gas constant R and get V = nRT/P This can be rearranged to give the IDEAL GAS LAW PV = nRT

    Though Lewis concept of acids and bases is more general than Arrhenius as well as Bronsted-Lowry concepts, yet it has several drawbacks which are discussed below:

    3Thank You

    Ayushi Ayushi 7 years ago

    1. Lewis concept gives the general idea and includes all the coordination reactions and coordination compounds. This may not be true always. 2. Lewis concept no don explain the behavior of well known protonic acids like HCl, H2SO4, etc. which do not form coordination bonds with bases. Therefore, according to Lewis, these are not regarded as acids. 3. Relative strengths of acids and bases are not explained by Lewis. 4. Many Lewis acids do not possess catalytic property. 5. Lewis Concept does not fit in the acid-base reaction concept.
