Which of the following is the correct complete ionic equation for the reaction between KI(aq) and Pb(NO₃)₂(aq)?Reaction: 2 KI(aq) + Pb(NO₃)₂(aq) → 2 KNO₃(aq) + PbI₂(s)A. 2K⁺(aq) + 2I⁻(aq) + Pb²⁺(aq) + 2NO₃⁻(aq) → 2K⁺(aq) + 2NO₃⁻(aq) + PbI₂(s) B. KI(aq) + Pb²⁺(aq) → K⁺(aq) + PbI₂(s) C. Pb²⁺(aq) + 2I⁻(aq) → PbI₂(s) D. Pb(NO₃)₂(aq) → Pb²⁺(aq) + 2NO₃⁻(aq)

Task: To review a 400–500-word outline of community identified needs, that presents five health and wellbeing priorities. Output: To explain how a community-centred approach would address the issues raised, and what methodology would be adopted. Written outputs should include: Explain what community centred approaches are. (K6) Outline one action that can be taken to achieve the community-centred approaches that value people as individuals. (K6, B11) Provide one example of how community centred approaches, that value people as individuals, can be applied to any of the health priorities mentioned in the scenario. (K6, B11) Describe two best practice methods (in line with the evidence) could be used to engage with the public and local communities, in order to deliver any of the health priorities mentioned in the scenario (K41, S30, S40, S37). Identify one behaviour change theory or model and show how this can be used at different levels to promote health for individuals, groups, and communities. (K42) Identify two factors or barriers that affect the ability of individuals to learn and develop within a community or work environment. (K50) Suggest two strategies (including tools & technologies) to improve health literacy in low literacy populations. (K38, B6)
