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.

What mass is in 5 moles of helium?
ArbitrLikvidat [17]

Answer:

Mass = 20 g

Explanation:

Given data:

Number of moles of He = 5 mol

Mass of He = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass = 4 g/mol

by putting values,

5 mol = Mass / 4 g/mol

Mass = 5 mol × 4 g/mol

Mass = 20 g

Exactly 10.0 L of air -25°C is heated to 100.0°C. What is the new volume if the pressure is kept constant?
zepelin [54]

Answer: V2= 15.0403226 Liters

Explanation:

Use V1/T1=V2/T2

Make sure you change the degrees Celsius to Kelvin. (Kelvin = degrees Celsius +273)

10.0L / 248 K = V2/ 373 K

Cross multiply V1 and T2 and divide by T1

(10.0 L)( 373K)/ 248 K = V2

V2= 15.0403226 Liters (Kelvin cancels out)
