ement of GAS molecules from one place to the other along the concentration gradient is called diffusion. When they are allowed to escape through a tiny HOLE under pressure, this PHENOMENON is called EFFUSION. RATE of diffusion of gas=Time takenVolume of the gas diffusion. r∝d 1. r2r1=d1d2.

The pH VALUE of 0.001 M of HCL is 3Explanation:The pH value is calculated by -log[H⁺] this H⁺ REPRESENTS the H⁺ ion concentration.so, the concentration is given 0.001 M. = 10⁻³ Mso, substituing the value, we get-log[10⁻³] Applying logarithm PROPERTIES log aˣ = x log a-(-3)= 3Hence, the pH of the solution is 3.

tion:ETHERS are generally not NUCLEOPHILES because while they do have an electronegative oxygen heteroatom, there is not a proton that can be removed to quench the positive charge in the intermediate. This means that ethers could be possible SN1 nucleophiles that produce a high energy product. In general it is reasonable to ASSUME that ethers will not act as nucleophiles.

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bonds" such as covalent, ionic and metallic bonds, and "weak bonds" or "secondary bonds" such as dipole–dipole interactions, the London dispersion force and hydrogen bonding. Since opposite charges attract via a simple electromagnetic force, the negatively charged electrons that are orbiting the nucleus and the positively charged protons in the nucleus attract each other. An electron positioned between two nuclei will be attracted to both of them, and the nuclei will be attracted toward electrons in this position. This attraction constitutes the chemical bond. Due to the matter wave nature of electrons and their smaller MASS, they must occupy a much larger amount of volume compared with the nuclei, and this volume occupied by the electrons KEEPS the atomic nuclei in a bond relatively far apart, as compared with the size of the nuclei themselves. In general, strong chemical bonding is ASSOCIATED with the sharing or transfer of electrons between the participating atoms. The atoms in molecules, crystals, metals and diatomic gases—indeed most of the physical environment around us—are held together by chemical bonds, which dictate the structure and the bulk properties of matter. Examples of Lewis dot-style representations of chemical bonds between carbon (C), hydrogen (H), and oxygen (O). Lewis dot diagrams were an early attempt to describe chemical bonding and are STILL widely used TODAY. Explanation:

:- Acid rain leaches aluminum from the soil. That aluminum may be harmful to PLANTS as well as animals. Acid rain also removes minerals and nutrients from the soil that trees NEED to grow. ... The trees are then less able to absorb sunlight, which makes them weak and less able to withstand FREEZING temperature...ACKNOWLEDGEMENT :- PLS MARK AS THE ANSWER AS BRAINLIEST FOR THE HARD WORK !!

Dynamic equilibrium only occurs in reversible reactions, and it's when the rate of the forward reaction is equal to the rate of the reverse reaction. These EQUATIONS are dynamic because the forward and reverse reactions are still OCCURRING, but the two rates are equal and unchanging, so they're also at equilibrium.bDynamic equilibrium only occurs in reversible reactions, and it's when the rate of the forward reaction is equal to the rate of the reverse reaction. These equations are dynamic because the forward and reverse reactions are still occurring, but the two rates are equal and unchanging, so they're also at equilibrium.cMain CHARACTERISTICS of chemical equilibrium:(1) At equilibrium, the rates of forward and reverse reactions are equal.(2) All the reactants and products are present at equilibrium.(3) The CONCENTRATIONS of the reactants and products reach constant values and these are called equilibrium concentrations.(4) A catalyst does not affect the position of equilibrium.Answered By

ete mix is said to be self-compacting concrete, if  it has all of the given optionsA self compacting concrete predominantly possesses three essential characteristics namely the passing ability, the flowing ability and the Resistance to segregation. A passing capability obtains the ability without congested reinforcement to pass through the SEPARATION of the components or the blocking. Flowing capability accurately represents the unique capability to completely SATURATE all key areas and operative corners of the formwork it is put in.  To maintain a HOMOGENEOUS material, segregation resistance REMAINS the ability to support the coarse components of the mix in suspension.
