Deserts I searched it and went through olds notes hope that helps!!!
Explanation:
Temperature has a direct relationship with reaction rate. The higher the temperature the faster the rate of reaction of a system.
- For every 10°C rise in temperature above the room temperature, it has been found that reaction rates becomes double or triple.
- When the temperature of a reacting system increases, the kinetic energy of each of the reacting particles increases.
- The frequency of collision and effective collision also increases per unit of time.
- Many of the reacting particles will acquire an energy greater than or equal to the activation energy of the reaction.
Answer:
No.
Sodium Chloride has a density of 2.17 g/cm3
Explanation:
-The resultant crystal is likely to be of Potassium Chloride
-The silvery metal is likely Potassium due to it's similar melting point of 63.5 °C which when reacts with Chlorine gas form a Potassium chloride with the following properties:
Hence, the crystal formed is not Sodium Chloride.
-The properties of sodium chloride are:
Answer:
Velocity = 120 km/h in north
Speed = 120 km/h
Explanation:
Given data:
Distance = 300 km north
Time taken = 2.5 hr
Speed and velocity = ?
Solution:
Speed = distance / time
Speed = 300 km / 2.5 h
Speed = 120 km/h
Velocity = change in position / change in time
Velocity = 300 km north / 2.5 hr
Velocity = 120 km/h in north
Answer:VO(ClO4)3 i'm sure this is it
