Answer:
Na+ ion is smaller than a neutral Na atom in the ion there was one more proton which will attract electron bring it closer to the center making the atomic radius smaller. Therefore making a Na+ ion is smaller than a neutral Na atom Explanation:
yes
Answer:
The ability to be maintained at a certain rate or level
Explanation:
Answer:
The answer to your question is 41.6 g of AgCl
Explanation:
Data
mass of NH₄Cl = 15.5 g
mass of AgNO₃ = excess
mass of AgCl = 35.5 g
theoretical yield = ?
Process
1.- Write the balanced chemical reaction.
NH₄Cl + AgNO₃ ⇒ AgCl + NH₄NO₃
2.- Calculate the molar mass of NH₄Cl and AgCl
NH₄Cl = 14 + 4 + 35.5 = 53.5 g
AgCl = 108 + 35.5 = 143.5 g
3.- Calculate the theoretical yield
53.5 g of NH₄Cl -------------------- 143.5 g of AgCl
15.5 g of NH₄Cl ------------------- x
x = (15.5 x 143.5) / 53.5
x = 2224.25 / 53.5
x = 41.6 g of AgCl
Answer: The final pressure will decrease ad the value is 85 kPa
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
![\frac{P_1}{T_1}=\frac{P_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2%7D%7BT_2%7D)
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
![P_1=100kPa\\T_1=60^0C=(60+273)K=333K\\P_2=?\\T_2=10^0C=(10+273)K=283K](https://tex.z-dn.net/?f=P_1%3D100kPa%5C%5CT_1%3D60%5E0C%3D%2860%2B273%29K%3D333K%5C%5CP_2%3D%3F%5C%5CT_2%3D10%5E0C%3D%2810%2B273%29K%3D283K)
Putting values in above equation, we get:
![\frac{100kPa}{333K}=\frac{P_2}{283K}\\\\P_2=85kPa](https://tex.z-dn.net/?f=%5Cfrac%7B100kPa%7D%7B333K%7D%3D%5Cfrac%7BP_2%7D%7B283K%7D%5C%5C%5C%5CP_2%3D85kPa)
Hence, the final pressure will decrease ad the value is 85 kPa
