Answer:
the number of protons is called the atomic number
hope it helps you buddy
Answer:
solid to liquid i think
Explanation:
entropy is natural disorder in simple terms- liquid the atoms are less organised than in a solid to increased entropy as they move apart becoming disordered
at least this is how i understand it
Answer:
I THINK it's D, I could be incorrect, however.
Explanation:
C3H8O, as it is flammable, and thus I wouldn't imagine it being a product of combustion. I could be incorrect, so take my answer with a grain of salt.
Answer:
- <em>The molar solubility is</em> <u>0.0118 mole / liter = 1.18 × 10⁻² M</u>
Explanation:
1) <em><u>Ksp </u></em>stands for product solubility constant.
2) The <u>product solubility constant </u>is the equilibrium constant used for the aqueous ionization (dissolution) of low soluble ionic compounds.
3) The ionization or <u>equilibrium</u> reaction for the PbBr₂ is:
- PbBr₂ (s) ⇄ Pb²⁺ (aq) + 2 Br(aq)⁻
4<u>) Sotichiometry</u>:
- PbBr₂ (s) ⇄ Pb²⁺ (aq) + 2 Br(aq)⁻
Ao - x moles x 2x
5) <u>Calculations</u><u>:</u>
Per definition of Ksp:
- Ksp = [Pb²⁺] [Br(aq)⁻]² = (x) (2x)² = 4x³
- Then, you have to solve: 6.60×10⁻⁶ = 4x³
- x = 0.0118 mole / liter = 1.18 × 10⁻² M
