Answer:
C₆H₅COOH Benzoic Acid
Explanation:
Here we are using the extraction method to separate benzoic acid from naphtalene in the ether solution by reacting it with the base sodium bicarbonate to produce the salt sodium benzoate ( naphtalene remains in the organic layer ) .
The sodium benzoate is completely soluble in the aqueous layer being a salt, and reacts with hydrochloric acid ( again an acid base reaction ) which precipitates the benzoic acid since the it is insoluble in water hence separating it.
Answer:
it will be the same on both sides of the membrane
A pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers.
The heat in the core of the Earth has several sources including:
1- The heat produced from the decaying of radioactive elements
2- The heat that was originally produced during the formation and accretion of the planet itself (This heat has not yet faded)
3- The heat produced during friction when denser material and elements sink into the planet's center.
