Answer:
True statement regarding phytoplankton is :
<u>They are the primary photosynthetic plants in the ocean</u>
<u></u>
Explanation:
Phytoplankton : It is made of two words :
"Phyto" means plants
"plankton" means drift .
Hence Phytoplankton are plants that live in water .They are also known as microalgae and are similar to terrestrial plants because they also contain chlorophyll .
Most phytoplanktons are found on the surface of water so that they can get enough sunlight to prepare their food .
There are two kinds of phytoplankton
a) dinoflagellates (they have tail or flagella)
b) diatoms (they are shell like)
<u>They provide food to many organism living in water . example : jelly fish , shrimps etc</u>
<u>Hence they balance the ecosystem</u>
<u>In this way they are primary producers in water -food chain</u>

Answer:
Ksp = [Ca⁺²] × [C₂O₄⁻²]
Explanation:
Step 1: Write the balanced reaction for the dissociation of calcium oxalate
CaC₂O₄(s) ⇄ Ca⁺²(aq) + C₂O₄⁻²(aq)
Step 2: Write the expression for the solubility product constant (Ksp) of calcium oxalate
The solubility product constant is the equilibrium constant for the dissociation reaction, that is, it is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It doesn't include solids nor pure liquids because their activities are 1.
Ksp = [Ca⁺²] × [C₂O₄⁻²]
Answer:
Answer: ... When iron is exposed to the environmental condition it terribly reacts with water and air and ends up with iron rusting. Iron articles are therefore painted off so that iron can not react with water and air.
