MTALHAHASSAN2 one year ago Need help!! Can someone please look at my all the answer on the worksheet

1. MTALHAHASSAN2

2. MTALHAHASSAN2

@eabollich here is a page 1

3. anonymous

Thank you, The images are still quite blurry, it might help if you type out the ones you are the least sure about. I do not have enough knowlege of isotopes and radioactive decay to answer those questions. The answer to number 20 is B, not A

4. anonymous

I can't read how many neutrons are in the nucleus of number 5

5. anonymous

Everything else seems fine

6. MTALHAHASSAN2

7. MTALHAHASSAN2

And also is 20 a or b

8. MTALHAHASSAN2

I mean the question 20

9. anonymous

I can't read the number inside of the nucleus of the atom in question #5. Question 20 is B.

10. MTALHAHASSAN2

It's 14 p and 17 n

11. anonymous

Great! You did a good job. I am not qualified to answer questions about isotopes and radioactivity but all of the other questions seem to be correct if you change #20.

12. MTALHAHASSAN2

What is 27

13. MTALHAHASSAN2

I did not get 27

14. MTALHAHASSAN2

This be page 2

15. MTALHAHASSAN2

16. anonymous

I don't see any question #27

17. MTALHAHASSAN2

Ok wait but can you plz see those worksheer

18. MTALHAHASSAN2

19. anonymous

Too blurry. From what I think the questions say, I am guessing that you answered them correctly though.

20. MTALHAHASSAN2

Which worksheet is blurry

21. MTALHAHASSAN2

both of them

22. MTALHAHASSAN2

@Data_LG2

23. MTALHAHASSAN2

@eabollich

24. MTALHAHASSAN2

@jagr2713

25. MTALHAHASSAN2

@Haseeb96

26. MTALHAHASSAN2

27. MTALHAHASSAN2

can you see it

28. MTALHAHASSAN2

29. MTALHAHASSAN2

Is anyone good in physics

30. IamStark

Can you please repost your question in a new thread one by one. It's quite confusing here.

31. MTALHAHASSAN2

ok wait I will try

32. MTALHAHASSAN2

33. MTALHAHASSAN2

@IamStark

34. MTALHAHASSAN2

35. MTALHAHASSAN2

@IamStark know its kind of better

36. MTALHAHASSAN2

37. MTALHAHASSAN2

what would be the answer for this one

38. MTALHAHASSAN2

I choose b

39. IamStark

ok, so in an $$\alpha$$ decay, a nucleus sheds two protons and two neutrons which are collectively called as an $$\alpha$$ particle. So, in this case the atomic number of the parent atom will decrease with 2 and the mass number will decrease with 4.

40. IamStark

Ar you getting my point?

41. MTALHAHASSAN2

yes so it b or d

42. MTALHAHASSAN2

hello

43. IamStark

You tell me, which one should it be?

44. MTALHAHASSAN2

d

45. MTALHAHASSAN2

right

46. MTALHAHASSAN2

hello

47. MTALHAHASSAN2

@iamMJae

48. MTALHAHASSAN2

are you there

49. IamStark

$$\huge \checkmark$$

50. MTALHAHASSAN2

ok so d is right

51. MTALHAHASSAN2

52. MTALHAHASSAN2

@taramgrant0543664 are you plz look at question 14

53. MTALHAHASSAN2

I mean can you plz look at question 14

54. taramgrant0543664

The carbon 14 one?

55. MTALHAHASSAN2

ye

56. MTALHAHASSAN2

The standard notation for carbon-14 is shown. How many neutrons does one atom of carbon-14 contain?

57. taramgrant0543664

Well I can just barely read it but if it's asking about neutrons which I believe it is there is 6

58. MTALHAHASSAN2

|dw:1436422055845:dw|

59. MTALHAHASSAN2

a)8 b) 20 c) 6 d) 14

60. MTALHAHASSAN2

so it be c

61. taramgrant0543664

Ya

62. MTALHAHASSAN2

63. MTALHAHASSAN2

Plutonium-239 undergoes alpha decay. Which general equation would you use to help write the nuclear reaction equation for this alpha decay

64. MTALHAHASSAN2

which one do you think

65. taramgrant0543664

B

66. MTALHAHASSAN2

are you sure

67. MTALHAHASSAN2

that what I get

68. taramgrant0543664

it has to produce He and that's the only one I saw with He but the picture is too blurry to make out the answers very well so I picked the only one that I was able to see He

69. MTALHAHASSAN2

oh yeah there is not He is other options

70. taramgrant0543664

No there isn't He in any of the other options

71. MTALHAHASSAN2

yes there is not

72. MTALHAHASSAN2

so what one be right

73. MTALHAHASSAN2

b

74. taramgrant0543664

The one with He in it

75. MTALHAHASSAN2

76. MTALHAHASSAN2

I get a

77. taramgrant0543664

Yes it's A

78. MTALHAHASSAN2

sure na

79. MTALHAHASSAN2

80. MTALHAHASSAN2

just plz help me with question 27

81. MTALHAHASSAN2

this is the last page

82. MTALHAHASSAN2

and also this is a better pic

83. MTALHAHASSAN2

just look at question number 26 to 29

84. MTALHAHASSAN2

plz

85. MTALHAHASSAN2

@taramgrant0543664 are you there

86. taramgrant0543664

Yes I'm still here it's called trying to read that sheet of paper you gotta give me a min you ask me 27 and then you ask me about the sheet so I have to look at all through so hold your horses I can't read that fast when the pic is a little blurry!

87. MTALHAHASSAN2

88. taramgrant0543664

26 is not A I don't know if you are eleminating that one or you're picking it but should be 32

89. taramgrant0543664

27 I would say is c

90. MTALHAHASSAN2

for which question

91. MTALHAHASSAN2

you mean question 26 is not a

92. MTALHAHASSAN2

ok

93. MTALHAHASSAN2

but how you get 32 for question 26

94. taramgrant0543664

The last two would be B and then D

95. MTALHAHASSAN2

what that I wrote

96. MTALHAHASSAN2

97. taramgrant0543664

mass number of 72 corresponds with Ge on the periodic table which has an atomic number of 32, protons and electrons are the same as the atomic number but neutrons don't follow that idea

98. MTALHAHASSAN2

can you plz look at it

99. taramgrant0543664

You do realize you said last sheet last time right? And you have that sheet fine but again it's hard to see

100. MTALHAHASSAN2

sorry dear this one is the last promice

101. MTALHAHASSAN2

so in question 5 they are asking for the mass number of the atom

102. MTALHAHASSAN2

14 p and 17 n

103. MTALHAHASSAN2

I get 31

104. MTALHAHASSAN2

c

105. taramgrant0543664

106. MTALHAHASSAN2

31

107. taramgrant0543664

Sure

108. MTALHAHASSAN2

in question 6 they are asking for the chemical name of the isotopes shown here

109. MTALHAHASSAN2

14 p and 17 n

110. MTALHAHASSAN2

a) oxygen -14 b) potassium-31 c) argon-17 d) silicon-31

111. taramgrant0543664

112. MTALHAHASSAN2

sure na

113. taramgrant0543664

These are the same questions as the sheet you had posted the answers were great

114. MTALHAHASSAN2

ok sure and thnx for the help. I appreciated

115. MTALHAHASSAN2

Thnx a lot sister

116. taramgrant0543664

No problem

117. MTALHAHASSAN2

I hope I will get full marks in it

118. MTALHAHASSAN2

let see

119. MTALHAHASSAN2

ok bye
