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:
5.19 m³
Explanation:
Data Given:
initial Pressure P1 = atmospheric pressure
Reported atmospheric pressure = 14.696 psi
Final pressures P2 = 68 psi
initial Temperature T1 = 26 °C
final Temperature T2 = 48 °C
initial Volume V1= 13 m³
final Volume V2 = ?
Solution:
Formula will be used
P1 V1 / T1 = P2 V2 / T2
To calculate volume rearrange the above formula
V2 = (P1 V1) T2 / T1 P2 . . . . . . . .(1)
put values in equation 1
V2 = (14.696 psi x 13 m³) 48 °C / 26 °C x 68 psi
V2 = (191.05 psi m³) 48 °C / 1768 °C psi
V2 = (9170.3 psi m³ °C / 1768 °C psi
V2 = 5.19 m³
So, final volume is 5.19 m³
Answer:
Yes, the data supports the researchers hypothesis.
Explanation:
From the given data, in all the cases except the fanning event in females, the fish parents which was fed full ration appeared.
Take for example, 30.7 mouthing events in males given full ration as opposed to 24.5 events when they were fed on half ration.

Answer:
The new temperature is 19.072 K.
Explanation:
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure. This law says that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules.
In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
Assuming that a certain volume of gas V1 that is at a temperature T1 at the beginning of the experiment varies up to a volume of gas V2, then the temperature will change to T2, and it will be true:
In this case:
- V1= 500 mL
- T1= 25 C= 298 K
- V2= 32 mL
- T2= ?
Replacing:
Solving:
T2= 19.072 K
<u><em>The new temperature is 19.072 K.</em></u>
