Answer:
Explanation:
a. the salt produced would be Mg3N2(magnesium nitride)
b. magnesium loses 2 electron to form Mg2+ ion and nitrogen gains 3 electron to form n3-
when several of these ions come together 3 Mg2+ ion combine with 2 n3- ion to form Mg3N2 thus Mg getting six electron from nitrogen to form a ionic bond.
c. the reaction is not balanced Mg + N2 = Mg3n2
to make it balanced the reaction should be 3 Mg + N2 = Mg3N2.
the reaction was not balanced before because the number of Mg on both side of the reaction was not equal.
d. magnesium nitrate has formula Mg(NO3)2 is formed when Mg combines with nitrogen and oxygen Mg + N2 + o2

Question:
A spring with a spring constant of 30 N/m is stretched 0.2 m from its equilibrium position. How much work must be done to stretch it an additional 0.1 m?
Elastic Potential Energy:
The work that needs to be done by any object is a form of energy. The work can be defined in terms of the work-energy theorem, which states that the work can either be the difference in the kinetic energy of a system or the difference in the potential energy of a system. There is a special type of potential energy reserved exclusively for
