Question

(1.5 point) 2. How many atoms of which elements are present in a molecule of CH3(CH2)2Cl? (2 points) 3. Which of the following equations are balanced? Show your work. a. 6Na + Fe203 2Fe+3Na20 b. MnO+ 4HCI MnCl2 + 2H20 + Cl c. C4H10+902 4CO2+5H2O d. 3H2S+2HNO3 3S+2NO + 4H2O

I need the answers for questions 2-3.

Answer 1

C (CH2), ce ts equivalent to caballo cha Modestam corrbon (C) atom = 3 No of hydrogen (H) atom = 7 No of chronne (1) alom = 1 a 6 nat h are + 3 Nazo In left side: Noof va atom - 6 No of fe alom =2 No of a worm = 3. bright side: Noof Wa atm = 6 noof fe alom = 2 wo of o alom = 3 in both sode no of each atom is same. so this na balenced equation, (5 mno+4 Hu Mnu +-240ta, In leffside, mo of Mn atom 1 No of o alom - wo of Hahn = 4 Nod u abm = 4 - In right side; no of mnahm=1 Norto atm =2 no of Ham= 4 no du atm = 4 As im left side no of oxygnatom ist where anmnight side no of o atomisz. le not some. Hence this is not a balenced equation,

G CA Hot qo 4 Co₂+540 Ineftnda noof calom = 4 wo of it alom = 10 No ofo whom = 18 right side: no of catm = 4 No of 4 Nom - 10 no of o abm = 13 As muft side and right side no of oxygen atom brott same, hence this is not a balanced equation. (2) 345+ 2 Ano, 31+ 2 Not 440 In left side: No of atom = 8 mofs abm = 3 no of N adom =2 mooto atm = 6 Im right side: No of it atm = 8 woots ahm =3 No of N abm=2 No of o atm = 6 right side the no of each abom vexactly same as that of the con left side. tone, this is a balemed equation.
