Answer: Option (d) is the correct answer.
Explanation:
Group 2 elements are also known as alkaline earth metals and they are rich in electrons.
For example, calcium is a group 2 element with atomic number 20 and its electronic configuration is 2, 8, 2. In order to gain stability, calcium loses to electrons and becomes ion.
Similarly, all the elements of group 2 donates electrons in order to form ionic bonds.
Hence, we can conclude that all group 2 elements have in common that they tend to form ionic bonds by losing electrons.
Answer : The heat energy absorbed will be,
Solution :
The process involved in this problem are :
The expression used will be:
where,
m = mass of ice = 1100 g
= specific heat of liquid water =
= enthalpy change for fusion =
Molar mass of water = 18 g/mole
Now put all the given values in the above expression, we get:
Conversion used : (1 cal = 4.184 J)
Therefore, the heat energy absorbed will be,
