Phosphorus has three electrons in its 3p sublevel and sulfur has four. Phosphorus should have the lower ionization energy but it

does not, sulfur does. Why? A. Phosphorus has 2 of its electrons paired in the 3p sublevel, which makes them harder to remove, or "ionize." B. Sulfur has 2 of its electrons paired in the 3p sublevel. The mutual repulsion of their negative charges makes them easier to remove, or "ionize." C. Because sulfur has more electrons, they are further from the nucleus and thus easier to remove and form an ion. D. Since sulfur has more electrons, it has more chances to form an ion.

Answer:

B

Explanation:

First of all it is important to know that a half filled orbital is particularly stable. In phosphorus all the electrons occur singly in the 3p sublevel minimizing inter electronic repulsion hence it is more difficult to remove an electron from this energetically stable arrangement. In sulphur, electrons are paired in one of the 3p orbitals thereby lowering the energy of that level due to instability caused by interelectronic repulsion between two electrons in the same orbital.

What are the conditions for evaporation?
SashulF [63]

Answer:

For evaporation you need a warm, preferably humid temperature. The rate of evaporation increases with an increase in temperature. A windy climate is best, as wind helps to remove the evaporated water vapour, and therefore creating a better scope for evaporation to continue. The speed of wind is important for evaporation because the wind pulls in dry air, increasing the rate of evaporation.

Short Answer- Hot and humid temperature, lots of wind speed.

Why do we observe national day​
WITCHER [35]

A national day is a day on which celebrations mark the nationhood of a nation or state. It may be the date of independence, of becoming a republic, or a significant date for a patron saint or a ruler (such as a birthday, accession, or removal). The national day is often a public holiday.

Un gas ocupa un volumen de 12 litros a una presión de 912 mm Hg. Si permanece constante la temperatura, ¿A qué presión el gas oc
adoni [48]

Answer:

The  pressure occupied is 1, 8 atm.

Explanation:

We use the Boyle´s Mariotte ´s law: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1= P2xV2. The unit of pressure is converted to mmHg in atm.

760 mmHg----1 atm

912 mmHg---x= (912 mmHg x 1 atm)/760 mmHg=1,2 atm

P1xV1= P2xV2

P2=P1xV1/V2= 1,2 atm x 12 L/ 8L= <em>1, 8 atm</em>
