B) full
When the moon is fully lit up, you can see all of it, therefore it is a full moon.
I think that scientist should build a habitat we’re the endangered animals could go free.By scientists building a habitat I mean giving the endangered animals a space to feel safe.Another way scientists could help endangered animals , would be to try and reproduce, the animal.For example scientist could help out with giving the animals hormones to be able to reproduce.And lastly scientists could do experimentation on the endangered animals to see if the animal ever were to go extinct how they could reproduce a new species.
Answer:
2.4 × 10⁻⁴ M
Explanation:
Step 1: Calculate the concentration of Mg²⁺ coming from Mg(NO₃)₂
Mg(NO₃)₂ is a strong electrolyte and the molar ratio of Mg(NO₃)₂ to Mg²⁺ is 1:1. The initial molar concentration of Mg²⁺ is 1/1 × 0.36 M = 0.36 M.
Step 2: Make an ICE chart for the solution of MgF₂
MgF₂(s) ⇄ Mg²⁺(aq) + 2 F⁻(aq)
I 0.36 0
C +S +2S
E 0.36+S 2S
The solubility product constant is:
Ksp = [Mg²⁺] × [F⁻]² = (0.36+S) × (2S)²
Since S <<< 0.36, 0.36+S ≈ 0.36.
Ksp = 0.36 × 4S² = 8.4 × 10⁻⁸
S = 2.4 × 10⁻⁴ M
