Answer: 1) Adding fertilizers to soil
Explanation: Eutrophication is the presence of excess mineral and nutrients in water bodies which result into increased plant and algal growth.
Fertilizers containing nitrogen and phosphorus are used to make soil more fertile in farming. The overuse of fertilizers can cause these nutrients to runoff the farmer's fields and enter water bodies, thus leading to eutrophication.
Answer:
B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]
Explanation:
For the reaction A + B → C
The formula for rate of reaction is:
Δ[C]/Δt = k [A] [B]
As you have [A], [B] and Δ[C]/Δt information you can multiply [A] times [B] and take this value as X and Δ[C]/Δt as Y. The slope of this lineal regression will be k.
Thus, you must obtain:
y = 3,60x10⁻² X
Thus, rate of reaction is:
B) Δ[C]/Δt = 3,60x10⁻² M⁻¹s⁻¹ [A] [B]

The correct classification of the solutes are as follows:
<span>hydroiodic acid hi = strong electrolyte
calcium hydroxide ca(oh)2 = weak electrolyte
hydrofluoric acid hf = weak electrolyte
methyl amine ch3nh2 = weak electrolyte
sodium bromide nabr = strong electrolyte
propanol c3h7oh = non electrolyte
sucrose c12h22o11 = non electrolyte
Strong electrolytes are substances that completely ionizes in aqueous solution while weak electrolytes are those that partially ionizes. Non electrolytes are substances that cannot conduct electric charge since there are no ions in the solution.</span>
