|
Answer» er: Hey mate HOPE it works ND hope it is helpful and correct for uu Explanation: Acids-Common aqueous acids include hydrochloric acid (a solution of hydrogen chloride which is found in gastric acid in the stomach and activates digestive enzymes), acetic acid (vinegar is a dilute aqueous solution of this liquid), sulfuric acid (used in car batteries), and citric acid (found in citrus fruits). Examples of acids include the inorganic substances known as the mineral acids—sulfuric, nitric, hydrochloric, and phosphoric acids—and the organic compounds belonging to the carboxylic acid, sulfonic acid, and phenol groups. Base-Examples of bases are the hydroxides of the alkali and alkaline earth metals (sodium, calcium, etc.) ... and the water solutions of ammonia or its organic derivatives (amines). Such substances produce HYDROXIDE ions (OH-) in water solutions (see Arrhenius theory). Salts-Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical COMPOUND belonging to the larger CLASS of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. ... Salt is essential for life in GENERAL, and saltiness is one of the basic human tastes. |

A compound is formed by three elements A ,B and C . Atoms of element B form hcp lattice . One eighth of tetrahedral void occupied by atoms of element A and One half of octahedral void occupied by atoms of element B . Formula of the compound is |
|
Answer» ong>ANSWER: Given that, atoms of B forms hcp lattice. So, the atoms at corners are shared by 6 unit cells. So, its contribution is 6 1
; Face centered atoms contribute 2 1
and middle layer atoms contribute 1 each. So, effective number of atoms in unit cell = 6 1
×12+ 2 1
×2+1×3 =2+1+3=6 Number of tetrahedral voids =2× Number of atoms forming the lattice. =2×6=12 So, number of atoms of A= 3 2
×12=8 Number of atoms of B=6 So, A:B⇒A:B 8:6 4:3 So, formula is A 4
B 3
