Moles of Cl2 = 2.65 x 10^24 / 6.02 x 10^23 = 4.4 moles.
Mass of Cl2 in grams = molar mass of Cl2 x moles of Cl2
= 70.906 x 4.4
= 311.98 grams.
Hope this helps!
Answer:
A
Explanation:
Since macroscopic means visible to the naked eye without a microscope it would be A. This is because we can see active phase changes in real time without any magnification like water boiling or ice melting.
Answer:
Plum pudding model
Explanation:
Thomson’s model of the atom called: PLUM PUDDING MODEL
Dissociation of Pb₃(PO₄)₂ is;
Pb₃(PO₄)₂(s) ⇆ 3Pb²⁺(aq) + 2PO₄³⁻(aq)
initial - -
change -X +3X +2X
Equilibrium 3X 2X
Ksp = [Pb²⁺(aq)]³ [PO₄³⁻(aq)]²
1.0 x 10⁻⁵⁴ = (3X)³ (2X)²
1.0 x 10⁻⁵⁴ = 108X⁵
X = 6.21 x 10⁻¹² M
Hence the molar solubility of Pb₃(PO₄)₂ is 6.21 x 10⁻¹² M.
Answer:
Lesson Summary. A substance is simply a pure form of matter. In other words, a substance is matter than contains only one type of atom or molecule. Pure substances can be further divided into two sub-categories: elements and compounds.
