If the temperature rises in a reaction. Exothermic is if it loses heat.
Have a nice day, brainliest would be fantastic.
The relation between force and mass and acceleration is
The SI unit will be
Force = Newton
mass =kg
acceleration=
thus
putting values
Thus the acceleration will be
Answer: Option (d) is the correct answer.
Explanation:
An atom or element which has the ability to readily gain an electron will have high electronegativity.
Both Beryllium and Calcium are alkaline earth metals and hence they are electropositive in nature.
Whereas both iodine and nitrogen are electronegative in nature. But across the period there is an increase in electronegativity and down the group there is a decrease in electronegativity.
Nitrogen belongs to period 2 and iodine belongs to the bottom of group 17. Thus, we can conclude that nitrogen is more electronegative than iodine.
