Answer:
(1). The pressure is 533 KPa.
(2). The temperature is 406 K.
Explanation:
Given that,
Number of moles = 4.52 moles
Volume = 21.0 L
Temperature = 298 K
(1). We need to calculate the pressure
Using ideal equation of gas
Where, T = temperature
R = gas constant
V = volume
n = number of moles
Put the value into the formula
(2). Number of moles = 1.60 moles
Volume = 21.0 L
Temperature = 298 K
We need to calculate the temperature
Using ideal equation of gas
Put the value into the formula
Hence, (1). The pressure is 533 KPa.
(2). The temperature is 406 K.
3 Cu + 8 HNO3 = 3 Cu(NO3)2 + 2 NO + 4 H2O i dont know how to explain it but this is the balanced equation basically all the atoms of every element has to be balanced
Answer:
a and b.
Explanation:
I am assuming you mean LICl and NaCl.
a and b are soluble in water.
AgCl is insoluble - If you add sliver nitrate solution (Ag NO3 ) to NaCl solution a white precipitate of AGCl is formed.
