D because animals changing colors is a mutation
The compound MgCl2(aq) is ionic which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MgCl2 that dissolves.
MgCl2(s) --> Mg+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.87 mol MgCl2/1L × 2 mol Cl⁻ / 1 mol MgCl2 = 1.7 M
The answer to this question is [Cl⁻] = 1.7 M
The correct answer should be A
Answer:
The new molarity is 0.614 M
Explanation:
Formula for dilutions is:
M concentrated . Volume of conc = Volume of dil . M diluted
6.54 M . 249 mL = 416 mL . M diluted
Notice that volume of diluted is = Initial volume + What we added of water
(249mL + 167 mL)
(6.54 M . 249 mL) / 416mL = M diluted → 0.614 M
