1.
To distinguish between a white precipitate of barium sulfate (BaSO4) and a white precipitate of barium phosphate (Ba3(PO4)2), one should add:
Concentrated nitric acid in the dark
Dilute hydrochloric acid (Ba3(PO4)2 dissolves while BaSO4 remains insoluble)
Ammonium hydroxide solution
Boiling distilled water
2.
The 7th term of the geometric sequence (2, 6, 18, ...) is:
729
162
1458
486
3.
The slope of the tangent line to the curve y = x2 - 6 x + 5 at the point (4, -3) equals:
m = 2
m = 8
m = -3
m = -2
4.
Using the Quotient Rule, the derivative of y = (x + 3) / (x - 2) for x != 2 is:
(2x + 1) / (x - 2)2
-5 / (x - 2)2
5 / (x - 2)2
1 / (x - 2)2
5.
The equation of the tangent line to the curve y = x3 at the point (1, 1) is:
y = 3x - 2
y = -3x + 4
y = 3x + 1
y = x
6.
The slope of the tangent to the curve y = (x + 1)/(x - 1) at x = 2 is:
-1
3
2
-2
7.
If the tangent to y = x2 - 4x + 5 is parallel to the x-axis, the point of tangency is:
(2, 1)
(0, 5)
(4, 5)
(2, 0)
8.
The volume expansion coefficient at constant pressure (alpha_v) of an ideal gas is physically measured using:
Joly's bulb apparatus or Charles's apparatus with a dry mercury droplet index
A torsion balance
A hydrometer
A venturi meter and manometer
9.
Vaccination gives humans immunity:
Temporary negativity that disappears within weeks
Not specialized
Innate, inherited
Acquired long-term positivity for the formation of memory cells
10.
In gene cloning technology, a ligase is used to:
Breaking down proteins
mRNA transcription
Cut the plasmid
Linking the integrated sticky ends of a target gene to the sticky ends of a circular plasmid
