sand and ammonium chloride are insoluble in water but sodium chloride is soluble in water .ammonium chloride sublimates. so you first heat the mixture in a beaker covered with a watch glass then the ammonium chloride will accumulate on the watch glass leaving a mixture of sodium chloride and sand you then dissolve the mixture then filter using a beaker and a filter paper the filtrate is salt solution while the residue is sand you then evaporate the salt solution to remain with salt
Answer: it think it would be last one. the mouth to the stomach is the answer.
Explanation:
Answer:
2D structure is based on skeletal formula and
3D structure is based on ball and rod model
Explanation:
Please find the attached image of 2 D and 3 D structure of cis-4-nonene
The 2D structure of Cis-4 nonene resembles the shape of skeletal formula. Almost every organic molecule has notation of skeletal formula. Each carbon atom is connected to sufficient number of hydrogen atom so that the valence of each carbon atom is satisfied.
The carbon atom is located at the corner while the hydrogen atom are not indicated.
The three dimensional structure of Cis-4 nonene is based on stick and ball model where ball represents the various types of atoms and the rod length represents the bond. White ball represents the hydrogen atom and grey ball represents the carbon atoms.
Answer : The incorrect option is, (d) The reactant that was the smallest given mass is the limiting reagent.
Explanation :
Limiting reagent : It is the reagent that is completely consumed in the chemical reaction when the chemical reaction is complete. No amount is left after the reaction is complete. The amount of product obtained is determined by the limiting reagent. A balanced equation is necessary to determine which reactant is limiting reagent.
Excess reagent : It is the reagent that are not completely consumed in the chemical reaction. That means the reagent is in excess amount. Some amount of the excess reagent is left over after the reaction is complete.
From this we conclude that the options, A, B and C are correct. While the option D is incorrect.
Option D is incorrect because it is not necessary the reactant that was the smallest given mass is the limiting reagent but it is judge by the number of moles present in the reaction.
Hence, the incorrect option is, (d)
