Answer:
Susan is right
Explanation:
Honey is a natural substance extracted from bees. Like every other natural substance, honey is a mixture of many different substances. An analysis of the so called 'pure honey' will reveal that many chemical species compose the natural substance called honey.
Hence Susan is right when she says that honey is not really pure but a mixture of substances.
Answer:
S = 1.1 × 10⁻⁹ M
Explanation:
NaCl is a strong electrolyte that dissociates according to the following expression.
NaCl(aq) → Na⁺(aq) + Cl⁻(aq)
Given the concentration of NaCl is 0.15 M, the concentration of Cl⁻ will be 0.15 M.
We can find the molar solubility (S) of AgCl using an ICE chart.
AgCl(s) ⇄ Ag⁺(aq) + Cl⁻(aq)
I 0 0.15
C +S +S
E S 0.15+S
The solubility product (Ksp) is:
Ksp = 1.6 × 10⁻¹⁰ = [Ag⁺].[Cl⁻] = S (0.15 + S)
If we solve the quadratic equation, the positive result is S = 1.1 × 10⁻⁹ M
Answer:
They are fossil fuels because they were formed because of fossilized remains of animals and plants that lived many years ago. They also have a high carbon content.
