Answer:
There are 3 significant figures
Plasma is the most least form on Earth and we hardly use it but it is the most common in the universe because it is mostly loacted in space
At 218 °C, solid NH₄SH decomposes to form 0.011 M NH₃ and H₂S, as given by its equilibrium constant.
<h3>What is the equilibrium constant?</h3>
The equilibrium constant (Keq) is the ratio of the product of the concentrations of the products to the product of the concentrations of the reactants, all raised to their stoichiometric coefficients.
Only gases and aqueous species are included.
- Step 1. Make an ICE chart.
NH₄SH(s) ⇋ NH₃(g) + H₂S(g)
I 0 0
C +x +x
E x x
- Step 2. Write the equilibrium constant.
Keq = 1.2 × 10⁻⁴ = [NH₃] [H₂S] = x²
x = 0.011 M

#SPJ1
when the thermal energy is the energy contained within a system that is responsible for its temperature.
and when the thermal energy is can be determined by this formula:
q = M * C *ΔT
when q is the thermal energy
and M is the mass of water = 100 g
and C is the specific heat capacity of water = 4.18 joules/gram.°C
and T is the difference in Temperature = 50 °C
So by substitution:
∴ q = 100 g * 4.18 J/g.°C * 50
= 20900 J = 20.9 KJ
It changes from a liquid from to a solid.
I hope this helps!
