Hint: Most stoneworts occur in water and customarily area units submerged and connected to the muddy bottoms of contemporary or briny rivers and lakes.
Complete answer:
a. Chara plants are called stoneworts - stone plants. The 'stony' part of the plant consists of carbonate within the sort of arduous crystalline spar that impregnates cell walls. spar is created by numerous teams of organisms, from the animate thing alga to shelly invertebrates. The spar protects these organisms from herbivores and predators.
b. Calcium salt hydrate (\[Ca{{C}_{2}}{{O}_{4}}~\cdot {{H}_{2}}O\]), additionally referred to as whewellite, could be a main element in excretory organ stones associated is an industrially helpful compound want to create acid and organic oxalates.
c. Calcium carbonate, naturally given in \[{{H}_{2}}O\], deposits carbonate on metal cathodes and stifles the reaction. Soluble salts of metallic element and metallic element act equally by causative hydroxide in neutral solutions
d. Calcium chloride happens in nature in its hydrous forms because the rare minerals sinjarite (dihydrate) and antarcticite (hexahydrate). it's conjointly found in giant amounts in natural brine from salt lakes and salt deposits.
Hence, option: ‘a. \[CaC{{O}_{3}}\]’ is the correct answer.
Note: The calcite-impregnated walls of Chara build this plant less appealing to grazers. The algae Chara is also known as stonewort, as its plant body is encrusted with calcium carbonate.
