Explanation:
The speed of molecules increases when temperature is increased as it will result in more number of collisions between the molecules. Thus, there will be increase in kinetic energy of molecules and increase in the speed of solvent molecules.
Whereas on decreasing the temperature, the kinetic energy of molecules will decrease. This will result in less number of collisions between the molecules. Therefore, the speed of solvent molecules will slow down.
Calcium carbonate is most likely to dissolve in water with:
e. Lots of Carbon dioxide and colder temperature.
Explanation:
- Calcium carbonate is very sparingly soluble in water. However, it has been observed to dissolve in cold water with higher concentration of Carbon dioxide.
- The reason behind the observation is the formation of Calcium bicarbonate which is soluble in water.
- Higher concentration of Carbon dioxide in water turns it acidic. When this acidic water reacts with calcium carbonate it forms Calcium bicarbonate which is soluble in water.
- So,Calcium carbonate is most likely to dissolve in water with lots of Carbon dioxide and colder temperature.
Yes , it does become massive and it also becomes heavier.
Answer:
Explanation:
From the question we are told that:
1st Energy 
2nd Energy 
3rd Energy 
Generally the equation for Energy E for electron in one dimensional box at ground state 
is mathematically given by
Therefore Length a is mathematically given as
