It would be CaF2 because you will need to balance then so since F is -1 it'll need another one to balance with Ca +2
The decay mode of cesium-137 is beta decay. This means that the cesium-137 decays into a beta particle and a nuclide with the same mass number, but with a charge number that is 1 more than that of cesium.
Therefore, this means Cs-137 decays into an electron and Barium-137, meaning the answer is choice 1.
Answer: See explanation
Explanation:
Based on the information given in the question, the ranking from the first step to the last step goes as follows:
1. Dissolution of salt into cations and anions
2. Hydration of anions
3. Hydration of cations
4. Dissolved cations and anions begin to deposit as a solid salt.
5. Rate of dissolution is equal to the rate of recrystallization.
Answer:
The temperature of the cold water is lower than the warm one. So, when we put the hand in the warm from the cold water, our hand will absorb heat, causing the hand to feel hot. Thus, we can conclude that the more heat it absorbs, the more hotter it is. Whereas the more heat it releases, the colder it is.
