One mole of acetyl chloride was mixed with one mole of dimethylamine. After the reaction is complete, what species can be found
fredd [130]

Answer:

N,N-dimethylacetamide is formed.

Explanation:

  • It is an example of a nucleophilic addition-elimination reaction. Here dimethylamine acts as a nucleophile.
  • In the first step, dimethyl amine gives nucleophilic addition reaction at carbonyl center of acetyl chloride.
  • In the second step, removal of Cl atoms occurs.
  • In the third step, deprotonation takes place from amino group to produce N,N-dimethylacetamide.
  • Full reaction mechanism has been shown below.

Is the specific heat capacity of a substance an intensive or extensive property? Explain.
andre [41]

The specific heat capacity is intensive, and does not depend on the quantity.

We can categorize a property of the compound as either intensive or extensive when defining a particular aspect of it. The extent of a drug or compound is a quality that is influenced by the sample size used. However, the intense property is independent of the quantity (we can say that it is independent on the amount of the sample used). One such example of an intensive property is density.

The specific heat capacity of a substance or a compound describes the amount of heat (in Joules) needed to increase the temperature of one gram of the substance by 1 unit.

The specific heat capacity is independent on the amount of substance used, therefore, it is classified as an intensive property of a substance. The specific heat capacity will not depend on the mass of the given substance and it will be a constant value for each substance.

So the specific heat capacity is intensive, and does not depend on the quantity, but the heat capacity is extensive, so two grams of liquid water have twice the heat capacitance of 1 gram, but the specific heat capacity, the heat capacity per gram, is the same, 4.184 (J/g.K).

Cell theory states that all the living organisms are made up of basic structural and functional units, cells. All cells divide and give rise to new cells. All the cells have similar chemical composition. The nuclei acid DNA present in the chromosomes helps in carrying hereditary information from generation to generation. So, in order to sustain life the cells must contain DNA either enclosed in the nucleus or freely floating in the cytoplasm.
