Answer: Option (A) is the correct answer.

Explanation:

A transition element is defined as the element which has incompletely filled d-orbital.

For example, atomic number of chromium is 24 and its electronic configuration is [Ar]4s^{1}3d^{5}.

Also, sometimes the s-orbital is completely filled and sometimes it is half-filled.

Hence, we can conclude that a single factor that classifies an element as a transition metal is that the  highest occupied orbital is a "d" orbital.

6) A 0.20 ml CO2 bubble in a cake batter is at 27°C. In the oven it gets
Nata [24]

Answer: The new volume of cake is 1.31 mL.

Explanation:

Given: V_{1} = 0.20 mL,         T_{1} = 27^{o}C

V_{2} = ?,                    T_{2} = 177^{o}C

Formula used to calculate new volume is as follows.

\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}

Substitute the values into above formula as follows.

\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}\\\frac{0.20 mL}{27^{o}C} = \frac{V_{2}}{177^{o}C}\\V_{2} = 1.31 mL

Thus, we can conclude that the new volume of cake is 1.31 mL.
