Answer:
This is a conversion factor
Answer:
that results in an alcohol and a carboxylic acid.
Explanation:
Saponification is a chemical reaction process of alkaline hydrolysis of esters(R'COOR group) by which soap is obtained.
For Example, when a base such as sodium hydroxide [NaOH] is used to hydrolyze an ester, the products are a carboxylate salt and an alcohol. Because soaps are prepared by the alkaline hydrolysis of fats and oils.
In a saponification reaction, alkaline hydrolysis of fats and oils with sodium hydroxide yields propane-1,2,3-triol and the corresponding sodium salts of the component fatty acids.
i.e Fat or oil + caustic alkali ⇒ Soap + propane-1,2,3-triol
As a specific example, ethyl acetate and NaOH react to form sodium acetate and ethanol:
The reaction goes to completion in the image below:
Molarity = mol/L
(0.5M) = (2mol)/L
(2mol)/(0.5M) = L

Rare earth metals are a group of 17 elements - lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium - that appear in low concentrations in the ground
Answer:
N2+O2→2NO
Explanation:
Dalton’s atomic theory is based on law of constant composition and law of conservation of mass.
One of the postulates of this theory is that rearrangement of atoms occurs during a chemical reaction. In other words, only rearrangement of elements occurs during a chemical reaction and elements remain the same.
So, among the given, the following reaction undergoes rearrangement of elements.
N2+O2→2NO
SO, only the above reaction is possible as per Dalton’s atomic theory.
