Hey there!
N₂ + H₂ → NH₃
Balance N.
2 on the left, 1 on the right. Add a coefficient of 2 in front of NH₃.
N₂ + H₂ → 2NH₃
Balance H.
2 on the left, 6 on the right. Add a coefficient of 3 in front of H₂.
N₂ + 3H₂ → 2NH₃
This is our final balanced equation:
N₂ + 3H₂ → 2NH₃
Hope this helps!
The particles of matter are in constant motion
The answer is D. The final substance in Beaker X is a mixture and in Beaker Y is a pure substance.
The question tells us that the sugar is not visible. This is because it is soluble. The sugar has dissolved into the water, making the two a mixture. The sand, on the other hand, is not dissolved at all. The water and sand are two separate pure substances.
The maximum concentration of calcium ions (Ca₂+) in a solution that
contains CO₃ will be 6.18 × 10⁻⁸. The correct option is D).
<h3>What is concentration?</h3>
The concentration of any substance is the presence or the amount of that substance in a specific place. It is also called the molar mass of the substance.
Ksp is the solubility equilibrium of a substance when it remains in its solid state.
The chemical equation will be
CaCO₃ ⇌Ca²⁺+CO₃²⁻
Ksp = [Ca²⁺][CO₃²⁻]
given Ksp = 3.4 × 10⁻⁹ [CO₃²⁻] = 0.055M
[Ca²⁺] = Ksp / [CO₃²⁻] 3.4×10⁻⁹ / 0.055 = 6.18 × 10⁻⁸
Thus, the Ksp of CaCO₃ = 6.18 × 10⁻⁸. The correct option is D).
