Answer:
2.178x10⁷kg, 2.178x10¹³mg, 2.178x10¹⁶μg, 2.178x10⁴ metric tons.
Explanation:
<em>The units are kg, μg, mg and metric tons (1metric ton = 1000kg)</em>
<em />
To solve this question we must convert, first, the grams to milligrams, and to kilograms. Then, the kilograms to metric tons and the milligrams to micrograms:
kg:
2.178x10¹⁰g * (1kg / 1000g) = 2.178x10⁷kg
mg:
2.178x10¹⁰g * (1000mg / 1g) = 2.178x10¹³mg
μg:
2.178x10¹³mg * (1000μg / 1mg) = 2.178x10¹⁶μg
metric tons:
2.178x10⁷kg * (1metric ton / 1000kg) = 2.178x10⁴ metric tons
Answer:
It can reduce soil erosion by %50 compared to up and down hill farming.
Explanation:
By reducing sediment and runoff and increasing water infiltration, contouring promotes better water quality.
Answer:
Solubility : The mass of a salt in grams that will dissolve in 100 mL of water
Saturated solution : A solution that has dissolved the maximum amount of a compound at a given temperature. Any further addition of salt will remain undissolved
Solubility product constant :The product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation
Common ion effect : A decrease in the solubility of an ionic compound as a result of the addition of a common ion
Molar solubility : The maximum number of moles of a salt that will dissolve in 1 L of solution
Explanation:
Solubility is expressed usually as the mass of solute per 100 grams or 100 ml of solvent.
Molar solubility of a solid is expressed as the concentration of the dissolved solid in a saturated solution.
Solubility product constant is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The common-ion effect is the decrease in solubility of a sparingly soluble salt by the addition to the solution of a soluble compound with an ion in common with the precipitate.
Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.
