Answer:
B. Ca(OH)2(s)+CO2(aq)-CaCO3(s)+H2O(aq)
Answer:
0.559 L
Explanation:
Step 1: Given data
- Moles of sodium iodide (n): 0.405 mol
- Molar concentration of sodium iodide (M): 0.724 M (0.724 mol/L)
Step 2: Calculate the volume of solution (V)
The molarity is equal to the moles of solute divided by the liters of solution.
M = n/V
V = n/M
V = 0.405 mol/(0.724 mol/L) = 0.559 L
Answer:
2Cr³⁺(aq) + 3S²⁻(aq) ----> Cr₂S₃(s)
Explanation:
When aqueous solutions of chromium(III) chloride and ammonium sulfide are mixed together, chromium (III) chloride and ammonium sulfide undergoes a double displacement reaction to produce chromium (iii) sulphide as a precipitate and ammonium chloride which remains in solution.
The general equation of the reaction is given below:
2CrCl₃(aq) + 3(NH₄)₂S(aq) ----> Cr₂S₃(s) + 6NH₄Cl(aq)
The net equation of the reaction is given below:
2Cr³⁺(aq) + 3S²⁻(aq) ----> Cr₂S₃(s)
Answer:
be able to meet long term timber needs.
Explanation:
Forest Services has been indicated for a long time the exhaustion of timer in the United States. However, in the recent decade, this trend has shown a reverse. The creation of nuclear energy and other technological developments that bring about drastic changes in our way of life. Gradually, the forest has recovered its trees and plants, and it is anticipated that timber will be available to meet long-term wood needs.
