Answer:
Molarity =moles /litre =moles /dm^3
... Yeah
Explanation:
The given data is as follows.
= 5.00 L, = ?
= -50.0 + 273 = 223 K, = 100.0 + 273 = 373 K
P = constant
Therefore, calculate as follows.
=
Since pressure is constant so, P will be cancelled out from both the sides.
=
=
=
=
= 8.36 L
Thus, we can conclude that is 8.36 L.
Answer:
AgNO3 precipitation test
pH test
Flame test
Explanation:
Starting with AgNO3 will help you clearly identify HCl, K2C2O4, Na2CO3 via double decomposition reaction. The colour of the precipitate will tell which solution has been identified. For instance, a white precipitate shows that the AgCl was formed from HCl.
pH test can identify HCl and Na2CO3 while flame test can only identify sodium carbonate and barium nitrate.
