Answer:
242.4 g
Explanation:
RAM of KNO3=39+14+(16×3)=101
Mass=morality×RAM
101*2.4=242.4
Salts that are from strong bases and strong acids do not hydrolyze. Salts that are from strong bases and weak acids do hydrolyze, which gives it a pH greater than 7. Salts of weak bases and strong acids do hydrolyze, which gives it a pH less than 7.
Answer: orientation , energy , frequency
Explanation:
According to the collision theory , the number of collisions that take place per unit volume of the reaction mixture is called collision frequency. The effective collisions are ones which result into the formation of products.
Effective collisions depends on the following two factors:-
1. Orientation factor: The colliding molecules must have proper orientation at the time of collision to result into formation of products.
2. Energy factor: For collision to be effective, the colliding molecules must have energy more than a particular value called as threshold energy.
Answer:
QP
Explanation:
P has 9 electrons.
Electronic Configuration : 2, 7
Valence electrons : 7
P needs 1 electron to get stable electronic configuration.
Q has 3 electrons.
Electronic Configuration : 2, 1
Valence electrons : 1
P needs to loose 1 electron to get stable electronic configuration.
Q donates 1 electron,
Q -----> Q+ + 1 e-
P gains 1 electron,
P + 1 e- -----> P-
Q+ + P- -----> QP
This is an ionic compound.
Answer:
The 2 ml and 2.0 ml is the same thing.
