An aqueous solution contains the following ions Cl⁻, Ag⁺, Pb²⁺, NO₃⁻ & SO₄²⁻ and more than one precipitate will form are AgCl, PbCl₂, PbSO₄ & Ag₂SO₄.

<h3>What is precipitate?</h3>

Precipitate is the insoluble compound which is present at the bottom of any chemical reaction in the solid state.

If in an aqueous solution Cl⁻, Ag⁺, Pb²⁺, NO₃⁻ & SO₄²⁻ ions are present then:

  • Compounds AgCl, PbCl₂, PbSO₄ & Ag₂SO₄ are not soluble in water as it is present in the form of precipitate.
  • Pb(NO₃)₂ is fully soluble in water and will not make precipitate.

Hence precipitates are AgCl, PbCl₂, PbSO₄ & Ag₂SO₄.

A strand of hair is approximately 50 μm thick. If the diameter of an atom is 1 × 10-10 m, how many atoms thick is a strand of ha
Kazeer [188]

Thickness of strand hair = 50 μm

Diameter of an atom  = 1 \times 10^{-10} m

Now, with the help of conversion factors, convert thickness in micrometer into meter i.e. 1 micrometer = 10^{-6}m

So, thickness of strand hair =50 μm= 50 \times 10^{-6} m

Therefore,

number of atoms thick is a strand of hair =  50 \times 10^{-6}m\times \frac{1 atom}{1 \times 10^{-10}m}

= 50\times 10^{4}atoms

Hence, number of atoms is 50\times 10^{4}atomsthick is a strand of hair.

Answer:

D . A substance with a pH of 8

Explanation:

pH stands for <em>"Potential for Hydrogen." </em>This is an indicator of a solution's acidity or alkalinity. It is also used to tell <em>which chemicals are great for cleaning. </em>

pH 7 and pH 8 are both considered<em> "neutral pH,"</em> thus, solutions with these pH are often used as<em> dishwashing detergents </em>because they do not destroy the surfaces of objects. However, pH 8 is said to be<u> more alkaline in nature</u>. This allows it to destroy the residues, such as <em>fats and oils</em>, in pots and pans. It is the<em> pH of baking soda.</em>

Why are ionic solids poor conductors of electricity
marshall27 [118]

Answer:

Ionic compounds don't conduct electricity very well because the charge carriers can't move through the crystal. They can conduct heat because the kinetic energy itself is the "heat carrier”.

Hope this helps :)
