Reproduction: It is a biological process in which an organism produces number of individuals or offsprings of  similar type. IMPORTANCE OF REPRODUCTION: 1) Continvity of species means group of individuals which are similar in morphology (external features) functions, behavior but they can reproduce sucessfully in natural condition. 2) It maintaines chromosome number. 3) It helps in replacement of organisms. BASIC FEATURES OF REPRODUCTION: Before reproduction these features are important. 1) Replication of DNA molecule means forming two or duplicate DNA copies. 2)Formation of RNA molecule, proteins, cells, cell organelles and other biochemicals. 3) Cell division [Mitosis_asexual/Meiosis_sexual]. 4) It helps in formation of separate reproductive units (Male/Female). 5) Formation of offsprings is due to combination of reproductive units. CELL DIVISION: It is the process by which a parent cell divides into two or more daughter cells .On the basis of cell division are two types of cell...

Why NaCl give s a white precipitate with AgNO³ solution but CCl⁴ does not?

By -
Q1.Why NaCl give s a white precipitate with AgNO³ solution but CCl⁴ does not? Ans. NaCl is an  ionic conpound and hence gives Cl‐ions in the solution which combine with Ag+ ions given by AgNO³ to fom a white precipitate of AgCl but CCl⁴ is a covalent compound and does not give Cl‐ions . Q2.Why reaction between NaCl and AgNO³  is very fast but reaction between H² and Cl² is slow? Ans. NaCl and AgNO³ are ionic compounds, In solution, NaCl gives Na+ and Cl_ ions and AgNO³, gives Ag+ and NO‐³ions. The oppositely charged Ag+and Cl+ ions combine immediately. The reaction betwecn H2 and Cl2 involves breaking of covalent bonds which requires energy.
