Many people believe that it is not right to use silk. Give reason why. |
Answer» Silk is the fiber that silkworms weave to make cocoons. To obtain silk, distributors boil the worms alive inside their cocoons. Anyone who has EVER SEEN worms startle when their dark homes are uncovered must acknowledge that worms are sensate—they produce endorphins and have a PHYSICAL response to pain. Humane alternatives to silk—including nylon, milkweed SEED pod fibers, silk-cotton tree and ceiba tree filaments, polyester, and rayon—are easy to find and usually less expensive, too.

Prepare orbital diagrame of methane molecule mention types of bonds and Angle of hybridization |
Answer» ORBITAL hybridization is the concept of mixing atomic orbitals into new HYBRID orbitals (with different energies, shapes, etc., then the component atomic orbitals) suitable for the pairing of electrons to form chemical BONDS in valence BOND theory.For example, in the ethane molecule, the BONDING structure according to valence orbital theory is very similar to that of methane. Both carbons are sp 3 -hybridized, meaning that both have four bonds arranged with tetrahedral geometry. | |

What are bases? what are acids?how neutral salt is formed?what happens when acid reacts with base? |
Answer» istry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases, and Lewis bases. All definitions agree that bases are SUBSTANCES which react with acids as originally proposed by G.-F. Rouelle in the mid-18th centuryAn acid is a molecule or ion capable of EITHER donating a proton, known as a Brønsted–Lowry acid, or, capable of forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acidsWhen a strong base reacts with a strong acid, a neutral SALT is formed. When a strong base reacts with a weak acid, a basic salt is formed. When a strong acid reacts with a weak base, an acidic salt is formed.The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water. ... For example, the reaction of hydrochloric acid, HCl, with SODIUM hydroxide, NaOH, solutions produces a solution of sodium chloride, NaCl, and some ADDITIONAL water molecules. |
