Molar solubility is number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.
The molar solubility of lead(ii) chloride with ksp value of 2.4 × 10e4 can be solve as:
Ksp = s2 = 2.4 × 10e4
s2 = 2.4 × 10e4
s = √(2.4 × 10e4)
s = 154.9 mol/L
It's A.
Chemical properties cannot be determined by viewing or touching substance, and physical properties can be measured without changing the composition of matter:)
The correct answer is b. an element
The explanation:
when the ELEMENT is define as substance that cannot be decomposed (broken down) into simpler substances by ordinary chemical means. Examples: gold, iron, carbon, hydrogen, oxygen, nitrogen
Ex: diamond will be broken into carbon as well.
and SUBSTANCE: Material composed of only one kind of matter throughout (same atoms or same molecules).
Added on wood, gasoline, wind
Answer:
covalent bond
Explanation:
covalent bond is a crystal structure in which the electrons do not leave their orbits.
