Answer:
Ecology is the study of the relationships between animals and plants in the environment.
Answer:
Explanation:
Homogeneous mixture is a mixture in which the components of the mixture are in the same proportion throughout any sample extracted from the mixture while an heterogeneous mixture is a mixture in which the components of the mixture differ in term of proportion when different samples of the mixture are extracted and compared.
For example, a sandy water will have some parts (usually the bottom) of the mixture with more sand than other parts of the mixture, hence, it (sandy water) is a heterogeneous mixture. While salty and ocean water has it's salt dissolved in the same proportion throughout the water in the mixture, hence salty and/or ocean water is a homogeneous mixture.
Sandy water can be separated by filtration (i.e using a filter paper to separate the sand from the water when the mixture is poured over a filter paper) while salty and ocean water can be separated by distillation (i.e boiling of the mixture so the water molecules can boil and move through a tube as gas or steam into another container where they are cooled and converted back to liquid or water while leaving the solid salt component of the mixture in the boiling tube).
Answer:
0.28M is molarity of iodide anion in the solution.
Explanation:
Molarity is defined as the ratio between moles of solute (In this case, iodine ion), per liter of solution (The total volume of the solution is 50.0mL = 0.0500L).
Thus, we need to convert mass of sodium iodide to moles using its molar mass (Molar mass NaI: 149.89g/mol). Moles of NaI = Moles of I⁻:
<em>Moles NaI = Moles iodide ion:</em>
2.07g * (1mol / 149.89g) = 0.01381moles NaI = Moles I⁻
Molarity is:
0.01381moles I⁻ / 0.0500L =
<h3>0.28M is molarity of iodide anion in the solution </h3>
Answer:
Evaporation
