NEED HELP ASAPP!! (If you could show any work that was needed to to this problem that would be greatly appreciated)

1. Interpret the following balanced chemical equations in terms of particles, moles, and
mass. Show that the law of conservation of mass is observed.
a. N2(g) + 3H2(g) → 2NH3(g)
b. HCl(aq) + KOH(aq) → KCl(aq) + H200
c. 2Mg(s) + O2(g) → MgO(s)
2. Challenge for each of the following, balance the chemical equation; interpret the
equation in terms of particles, moles, and mass, and show that the law of conservation
of mass is observed.
a.
Na(s) + H2000 - NaOH(aq) + H2(g)
b. Zn(s) + HNO,(aq) - Zn(NO)2(aq) + N2O(g) + H2001

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic

What are the variables in gay-lussac’s law? pressure and volume pressure, temperature, and volume pressure and temperature volume, temperature, and moles of gas

What material does not melt at any temperature
