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
If CFC increases, there will be a ozone depletion ! the UV rays starts entering and leads to mutation and deaths !
the temperature of the climate increases drastically !
Answer:
Roxanne said it was because chlorine is highly electronegative and sodium has a low ionization energy and that the ions Na and cr both have full electron shells.
You can use the equation f(t) = 5*(1/2)^(t/8.02)
Then plug in 6.01 for time.There remains 2.97 mg in the sample.
Mass percentages of the the elements in the compound is the only additional information needed to calculate the empirical formula of a compound if the masses of each element of the compound are provided.
<h3>What is Empirical Formula ? </h3>
The Empirical formula is the simplest whole number ratio of atoms present in given compound.
<h3>What is Molecular formula of Compound ?</h3>
Molecular Formula = Empirical Formula × n
n = 
Thus from the above conclusion we can say that Mass percentages of the the elements in the compound is the only additional information needed to calculate the empirical formula of a compound if the masses of each element of the compound are provided.
