Q. What is the coordination number of the central metal ion in the complex [Co(NH3)6]Cl3?
A.
2
B.
4
C.
6
D.
8
Solution
The coordination number is determined by the number of ligands attached to the central metal ion. In [Co(NH3)6]Cl3, there are six NH3 ligands, so the coordination number is 6.
Q. What is the correct way to express 0.0001234 in scientific notation with significant figures?
A.
1.234 x 10^-4
B.
1.23 x 10^-4
C.
1.2340 x 10^-4
D.
1.2 x 10^-4
Solution
In scientific notation, all non-zero digits are significant. Therefore, 0.0001234 can be expressed as 1.234 x 10^-4, maintaining all significant figures.
Q. What is the correct way to express 0.000345 in scientific notation with significant figures?
A.
3.45 x 10^-4
B.
3.450 x 10^-4
C.
3.4500 x 10^-4
D.
3.4 x 10^-4
Solution
In scientific notation, all digits in the coefficient are significant. Therefore, 0.000345 is expressed as 3.45 x 10^-4, which has 3 significant figures.
Q. What is the critical angle for total internal reflection if the refractive index of the medium is 1.5?
A.
30 degrees
B.
45 degrees
C.
60 degrees
D.
90 degrees
Solution
The critical angle (θc) can be calculated using sin(θc) = 1/n. Here, n = 1.5, so θc = sin^(-1)(1/1.5) ≈ 41.81 degrees, which is approximately 42 degrees.
Q. What is the critical angle for total internal reflection in a medium with a refractive index of 1.5?
A.
30 degrees
B.
45 degrees
C.
60 degrees
D.
90 degrees
Solution
The critical angle (θc) can be calculated using sin(θc) = 1/n. For n = 1.5, sin(θc) = 1/1.5 = 2/3. Therefore, θc = sin^(-1)(2/3) which is approximately 41.81 degrees, closest to 45 degrees.
