Chemistry · Question 66
Atoms with a completely filled valence shell are generally described as chemically:
Highly reactive
Relatively inert
Always positively charged
Always negatively charged
Show AnswerHide Answer
Correct answer: B
Relatively inert
A filled valence shell usually gives low chemical reactivity. Relatively inert does not mean that reaction is impossible under every condition.
Verbal Intelligence · Question 67
If 2 : 9 = x : 18, what is x?
2
3
4
6
Show AnswerHide Answer
Correct answer: C
4
Cross-multiplication gives 9x = 36, so x = 4.
Verbal Intelligence · Question 68
Evaluate 5005 - 5000 / 10 using the standard order of operations.
50
0.5
5000
4505
Show AnswerHide Answer
Correct answer: D
4505
Do division first: 5000 / 10 = 500. Then 5005 - 500 = 4505.
Verbal Intelligence · Question 69
A garden mixture contains 20 pails of clay, 15 pails of sand and 5 pails of manure. What is the ratio in simplest form?
4 : 3 : 1
4 : 3 : 2
20 : 15 : 5
10 : 7 : 3
Show AnswerHide Answer
Correct answer: A
4 : 3 : 1
Divide all three quantities by their greatest common divisor, 5: 20 : 15 : 5 becomes 4 : 3 : 1.
