Correct Answer: C. Two males

Correct Answer: D) it has incomplete outer shell d-electrons

Explanation

Option A suggests that a transition metal has an octet configuration. However, this is not true. Transition metals usually have more than eight electrons in their outer shell, and they can also have incomplete d-orbitals.

Option B states that a transition metal is very stable. While transition metals are generally stable, this is not a defining characteristic that sets them apart from non-transition metals.

Option C mentions that a transition metal is coloured. This is true for many transition metals, but not all of them. Also, some non-transition metals can be coloured too, so this is not a definitive characteristic.

Option D is the correct answer. A transition metal has incomplete outer shell d-electrons. This is what sets them apart from non-transition metals. The d-electrons in transition metals are responsible for their unique physical and chemical properties.

Option E states that a transition metal has no electron in the d-orbital. This is not true, as transition metals have electrons in their d-orbitals.

In summary, the correct difference between a transition metal and a non-transition metal is that a transition metal has incomplete outer shell d-electrons. This is what gives them their unique properties.

Correct Answer: D. Production of effervescence with saturated Na₂CO₃solution

Correct Answer: D. Ghana

Correct Answer: A. sulphur

Correct Answer: B. 60\(^o\)

Explanation

3\(x^o\) + 2\(x^o\) + 4\(x^o\) + 3\(x^o\) + 6\(x^o\) = 540\(x^o\)

\(\frac{18x^o}{18} = \frac{540^o}{18}\)

\(x^o\) = 30\(^o\)

Smallest angle = 2 x 30\(^o\) = 60\(^o\)

Correct Answer: B. gratitude

Correct Answer: A. drought

Correct Answer: A. 113\(cm^3\)

Explanation

Surface area of a sphere = \(4 \pi r^2\)

\(4 \pi r^2\) = \(\frac{792}{7}cm^2\)

4 x \(\frac{22}{7}\) x \(r^2\) = \(\frac{792}{7}\)

\(r^2\) = \(\frac{792}{7}\) x \(\frac{7}{4 \times 22}\)

= 9

r = \(\sqrt{9}\)

= 3cm

Hence, volume of sphere

= \(\frac{4}{3} \pi r^3\)

= \(\frac{4}{3} \times \frac{22}{7} \times 3 \times 3 \times 3 \)

= \(\frac{4 \times 22 \times 9}{7}\)

\(\approx\) = 113.143

= 113\(cm^3\) (to the nearest whole number)
