Answer:
the water has greater salinity
Explanation:
The term "Salinity" refers to the amount of salt present in water. Recall that the amount of solute increases when the volume of solution decreases. This is because the amount of substance present in a solution depends on the volume of the solution.
Hence, as water evaporates, the volume of the solution decreases and the salinity (amount of salt present) increases.
Answer:
0.642 g
Explanation:
La ecuación balanceada es:
- 2Mg + 2CuSO₄ + H₂O → 2MgSO₄ + Cu₂O + H₂
Primero <u>convertimos 1.89 g de Cu₂O en moles</u>, usando su <em>masa molar</em>:
- 1.89 g ÷ 143.09 g/mol = 0.0132 mol Cu₂O
Después <u>convertimos moles de Cu₂O en moles de Mg</u>, usando los <em>coeficientes estequiométricos</em>:
- 0.0132 mol Cu₂O * = 0.0264 mol Mg
Finalmente <u>convertimos moles de Mg en gramos</u>, usando la <em>masa molar de Mg</em>:
- 0.0264 mol Mg * 24.305 g/mol = 0.642 g
140.116 u ± 0.001 u is the answer
