Answer:
D) 6
Explanation:
The balanced equation would be:
6Li + N2 -> 2Li3N
Answer:
Refer to the period table. Use the atomic mass for calculation. Multiply the atomic mass with the number of atoms. For example, Al2(SO4)3. (27 × 2) + (32 x 3) + (16 x 12) = molecular mass
Here are some disadvantages, is that nitrogen dioxide is a toxic gas and it can still be harmful when ingested by human, also critics of hydrogen fuel cells argue that although these cells do not emit carbon after burning, they give out nitrogen dioxide and other emissions.

Answer:
k = -0.09165 years^(-1)
Explanation:
The exponential decay model of a radioactive isotope is generally given as;
A(t) = A_o(e^(kt))
Where;
A_o is quantity of isotope before decay, k is decay constant and A(t) is quantity after t years
We are given;
A_o = 5 kg
A(10) = 2kg
t = 10 years
Thus;
A(10) = 2 = 5(e^(10k))
Thus;
2 = 5(e^(10k))
2/5 = (e^(10k))
0.4 = (e^(10k))
In 0.4 = 10k
-0.9164 = 10k
k = -0.9164/10
k = -0.09165 years^(-1)
Salt
Explanation:
Of the listed substances, salts would have the highest melting point.
Salts are ionic compounds that are bounded by strong electrostatic forces.
In an ionic compound, metal and non-metal bond together through electrostatic attraction of their ions.
- Melting point is a property induced but intermolecular forces.
- It is known that salts have very strong intermolecular forces between them.
- They exhibit ionic crystal lattice forces.
- They are the strongest forces.
- They are strong electrostatic attraction between oppositely charged ions arranged into a crystal lattice of ionic compounds.
