    The salt is BAKING SODA or SODIUM BICARBONATE (NaHCO3). It is prepared by passing carbon dioxide through ammoniacal brine. "NaCl+H2O+NH3+CO2->NaHCO3+NH4Cl". Baking soda is insoluble in water but the ammonium byproduct is soluble. So, the crystals can be obtained by FILTRATION. Baking Soda is also used in SODA ACID FIRE EXTINGUISHERS and in ANTACID TABLETS.

    This is because these chambers receive blood from outside the heart ie, from cells who through diffusion, expels out the carbon dioxide into the blood which was formed as byproduct of oxidation of glucose in the mitochondria of the cells and takes in as much oxygen from the blood as possible. So, [O2] < [CO2].

    (i) Spore formation in Rhizopus: This is an asexual method of reproduction in bacteria and fungi. Spores are unicellular bodies formed by cell division in a parent organism. After detaching from the parent, and if conditions are suitable, they germinate directly or indirectly into a new individual. (ii) Multiple fission in Plasmodium: It is an asexual mode of reproduction in organisms. Here, the nucleus of the organism divides repeatedly to form a number of equal sized daughter nuclei and each daughter nuclei breaks away together with a small portion of the cytoplasm.
