Answer:
Rock
Explanation:
A rock is a solid mixture of one or more minerals and organic matter. Rock is often defined as an aggregate of minerals.
Minerals are solids that are made up of inorganic materials with a definite composition and a well ordered arrangement.
- Rocks are usually classified based on their mode of formation.
- They are often grouped as igneous, metamorphic and sedimentary.
The molarity of the aqueous acid solution : 0.0101 M
<h3>Further explanation </h3>
Titration is a procedure for determining the concentration of a solution by reacting with another solution that is known to be concentrated (usually a standard solution). Determination of the endpoint/equivalence point of the reaction can use indicators according to the appropriate pH range
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence (amount of H⁺, OH⁻)
Va=12.5 ml
na = 2 (H₂SO₄⇒2H⁺+SO₄²⁻⇒2 ion H⁺)
Mb=0.015
Vb=16.8 ml
nb = 1(LiOH⇒Li⁺+OH⁻⇒1 ion OH⁻)
The molarity of the acid(Ma) :
Answer:
The main difference between distillation and fractional distillation are:Simple distillation separate liquid with boiling point gaps of at least 50 degrees whereas fractional distillation separates liquid with closer boiling point.
