Answer:
CuSO4(aq) + 4NH3(aq) + nH2O→ [Cu(NH3)4H2On]S04(aq)
Explanation:
When the concentrated ammonia is added into the copper ions solution, a blue solid is formed. This blue solid is gelatinous.it consist of Cu(OH)2 in insoluble form. As more ammonia is added precipitate start to dissolve and [Cu(NH3)4]∧+2 is produce.
Net Ionic equation:
Cu∧+2 +4NH3 → [Cu(NH3)4]∧+2
S04∧-2 are spectator ions.
Properties and uses of Tetraaminecopper(ll) sulfate:
1. It is solid compound.
2. Its color is dark blue.
3. It has ammonia like odor.
4. It is used to make the copper compounds and also used in the printing of fabric.
5. It is also used as pesticide.
Answer:
b) Industrial farming
Explanation:
The term “industrial agriculture” refers to the type of farming which raises and cultivates large numbers of livestock and plants in high-density environments. It uses modern technology to promote faster growth and reduce illness and death rates in livestock, creating food products on a mass scale.
Answer:
The answer to your question is 0.33 moles of H₃PO₄
Explanation:
Data
moles of Ca(OH)₂ = 0.050
moles of H₃PO₄ = ?
Process
1.- Write the balanced chemical equation
3Ca(OH)₂ + 2H₃PO₄ ⇒ Ca₃(PO₄)₂ + 6H₂O
Reactants Elements Products
3 Ca 3
12 H 12
14 O 14
2.- Calculate the moles of phosphoric acid
3 moles of calcium hydroxide --------------- 2 moles of phosphoric acid
0.5 moles of calcium hydroxide ----------- x
x = (0.5 x 2)/3
x = 0.33 moles
The answer here would be 14.9 %KCl and here is how I can explain why:
33.5g / 225.6g x 100% = 14.9%
<span>you are looking for % of KCl in the solution, you have to add the mass of the KCl and water to get the total mass of the solution
Hope this helps a lot
