Answer:
Dispersants
Dispersants are generally detergents or surfactants that help dissolve the oil stain in smaller drops. They remove oil from the water surface, making it enter and into the water column, increasing the speed of biological degradation. These dispersants, by removing oil from the water surface, protect birds, marine mammals, turtles and sensitive coasts. Chemical dispersants do not sink oil leaving it suspended in the water column. Dispersants should be avoided in shallow coastal waters, mangroves, swamps, or waters over coral reefs and algae due to their possible toxicity.
Explanation:
<span>DG = DH - TDS
For this reaction DH>0 and DS<0. So, d. the reaction is not spontaneous at any temperature.</span>
Answer:
Concentration of stock solution in g/L = 5.0g/L
Concentration of stock solution in mol/L = 0.00117 mol/L or 0.00117 M
Explanation:
Concentration in mol/L = (Concentration in g/L)/(Molar mass)
Mass of (NH₄)₃Fe(ox)₃.3H₂O stock = 125mg = 0.125g
Volume of stock solution required = 25mL = 0.025 L
Concentration in g/L = 0.125/0.025 = 5.0 g/L
Molar Mass of (NH₄)₃Fe(ox)₃.3H₂O = (NH₄)₃Fe(C₂O₄)₃.3H₂O = 428.0632 g/mol
Concentration in mol/L = 5/428.0632 = 0.00117 mol/L = 0.00117 M
Hope this helps!!!
