1.) A compound is a substance that originates from two or more separate elements. It shares some similarities with a mixture.
2.) A compound has quite different properties from which it was formed. It also cannot be separated easily. Compounds are formed by chemical reactions.
3.) A pure substance has a constant composition and has consistent properties. It can be a compound or an element, but its composition is constant.
Hope this helps. :)
Answer:
802.69 g
Explanation:
The molar mass of Barium nitrite is 229.34 g/mol, so 3.5 moles of it will have a mass of ...
3.5 mol × 229.34 g/mol = 802.69 g
Answer: 0.811m
Explanation: Molarity is the moles of solute present per kg of solvent.
Molar mass of C10H8 = . 128.17 g/mol
No. of moles = given mass/molar mass
11.2g C10H8 = 11.2/128.17 g/mol C10H8
= 0.0874 mol C10H8
NOW 107.8g solvent (chloroform) contains 0.0879 molecules (naphthalene)
1000g '' will contain (0.0879/107.8 x 1000) mole solute
= 0.811 mole
Molarity of the solution is 0.811 m (option A)
Avogadro's number includes all real numbers . A mole concludes of the x as well as the number above which is to the power of how ever many zeros there is
Answer:
Anabolic reaction are specific type of reaction in which molecules joined together to form more complex molecules.
Explanation:
Metabolic reactions are catagorized into 2 types
1 Catabolic reactions: chemical or biochemical reactions that helps in the breakdown of complex molecules such as lipid,proteins and carbohydrates to convert them into their monomeric substituents such as fatty acid,amino acids and monosaccharides. Catabolism or breakdown of macromolecules proceed with the generation of free energy in form of ATP.
2 Anabolic reactions : Anabolic reactions can be defined as chemical or biochemical reactions in which molecules are joined to form more complex molecules.For examples monosaccharides can be joined by glycosidic linkages to form polysaccharides,amino acids can be joined with peptide bonds to form polypeptide chains which further constitute a protein.Anabolic reactions requires free energy from outside source .
