25:01 Na - metal , Cl - negative

20:20 heavy water is denoted by D2O C) moderator in nuclear reactants

19:47 c) Tih2

19:47 c) Tih2

19:18 litium as it's single valence electrons is very close to nucleus

18:36 bromine has atomic number 35 and belong to p block

24:59 Na - metal Cl - non metal

4:49 be,mg,ca etc can be called as earth metal

20:16 answer = denoted by D2O , uses in moderator nuclear reactants

19:56 answer= TiH2

19:12 answer = Lithium ( Li)

18:45 p- block bromine ( Br) = 35 atomic number , 79.904 atomic mass

4:57 located in group (1 and 2) Alkali = Li , Na Alkaline= Be, Mg

3:55 = (Tih2)

5:00 example = Be , Ca ,Ba , etc .

5:00 S - Block = alkaline Alkali earth metal

4:00 answer is TiH2

20:18 c. Moderator in nuclear reactants Heavy water is denoted by D2O

19:50 c. TiH2

18:47 b. P-block Atomic no. 35 Atomic mass. 79.9

3:54 TiH2

24:56 Na= metal Cl= non metal

24:58 Nacl. Na= metal , cl= non- metal

24:55 Na- metal , Cl- non metal

Thank you miss! Very helpful lecture! 🙏❤!!

27:46 Q.2 answer anatic

27:00 sodium saccharin ( 300 time's more sweetness)

26:40 sodium saccharin 300 time more sweet

26:40 sodium sccharin as its 300 time more sweeter than n sugar

26:57 sodium saccharin (300 times more sweet)

very nice explanation sir.. keep going

41:43 6'6nylon

54:22 pepsin as it help to berak protein

53:39 maltose

25:08 acetyladehyde

23:25 hg= mercury

15:27 sodium looses energy

12:44 propyl chloride

31:17 (halogenation, hydrogenation)

41:37 Q.2) answer = naylon- 6

41:13 Q.1) answer= Tetra fluoro ethane

41:39 nylon -6, 6

54:20 Pepsin = break down protein in stomach

53:37 B) maltose

54:16 pepsin

41:33 nylon

40:46 tetra fluoro ethane

54:17( C) pepsin

53:38 (B) maltose

54:28 pepsine , because it breaks the protein in the stomach
