question 4

Multiple Choice

Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of lithium sulfide and copper (II) nitrate are mixed.

• A)Li⁺(aq)+ SO₄^2-(aq)+ Cu⁺(aq)+ NO₃^-(aq)→ CuS(s)+ Li⁺(aq)+ NO₃^-(aq)
• B)Li⁺(aq)+ S^-(aq)+ Cu⁺(aq)+ NO₃^-(aq)→ CuS(s)+ LiNO₃(aq)
• C)2 Li⁺(aq)+ S^2-(aq)+ Cu²⁺(aq)+ 2 NO₃^-(aq)→ Cu²⁺(aq)+ S^2-(aq)+ 2 LiNO₃(s)
• D)2 Li⁺(aq)+ S^2-(aq)+ Cu²⁺(aq)+ 2 NO₃^-(aq)→ CuS(s)+ 2 Li⁺(aq)+ 2 NO₃^-(aq)
• E)No reaction occurs.

Definitions:

Biological Model

A representation of a biological process or system, often using mathematical equations or computer simulations, to study complex phenomena in biology.

Positive Feedback Loop

A process where the output of a system amplifies the initial condition, leading to an even greater output in a self-reinforcing cycle.

Negative Feedback Loop

A regulatory mechanism in which a system responds in a way that reverses the direction of a change, helping to maintain stability or equilibrium.

Mathematical Models

Quantitative representations of real-world phenomena constructed using mathematical language and symbols to predict or analyze behavior and events.
