<span>1.Which best explains why ionization energy tends to decrease from the top to the bottom of a group?
D.Electrons get farther from the nucleus. </span>They experience a weaker attraction to the positive charge of the nucleus.<span>
3.When electrons are removed from the outermost shell of a calcium atom, the atom becomes
D. a cation that has a smaller radius than the atom. </span><span>Since the atom is losing an electron, it not only becomes positively charged, also the effective nuclear charge diminishes making the remaining electrons aproach the nucleus.</span>
Answer:
My name is Andreas Vesalius and I'm a 16th-century Flemish anatomist, physician, and author of one of the most influential books on human anatomy, De Humani Corporis Fabrica Libri Septem. I am often referred to as the founder of modern human anatomy. I was born in Brussels, December 31, 1514 which was then part of the Habsburg Netherlands. I was a Flemish doctor who was notable for my contribution to the science of anatomy of the human body. I was the first to perform public dissection on a human corpse, a practice that was unusual in the Middle Ages due to spiritual beliefs.
Explanation:
The stronger intermolecular force has been found in glycerol with high viscosity as it has a larger molar mass. Thus, option A is correct.
The viscosity has been defined as the resistance of the fluid to the deformation. The viscosity has been dependent on the molar mass and intermolecular force in the compounds.
The stronger intermolecular force and molar mass tend to have more resistance to the deformation and thus have more viscosity.
The intermolecular force present in glycerol and water is hydrogen bonding. The molar mass of glycerol has been higher than water, this tends to have more resistance and viscosity.
Thus, glycerol has high viscosity as it has a larger molar mass. Thus, option A is correct.

Answer:
Between -195°C to -215°C
Explanation:
We begin from this data:
P under -220°C will be solid, because -220°C is the freezing point.
Above -220°C, P will be at liquid state.
Then -185°C is the boling point, so above that temperature we have P as a gas.
Between -175°C to -210°C
Above -185°C we said that P is gas, so at -175°C P is not liquid. This state is F.
Between – 190°C to -225°C
At -190°C, we can have P as liquid, but -225°C is under -220°C, where P changes from liquid to solid. Then, this state is also F.
Between -200°C to -160°C
Above -185°C we said that P is gas, so at -160°C P is not liquid. This state is also F. The same, as the first situation.
Between -195°C to -215°C
-195°C is a lower temperature than -185°C. P is still liquid, we did not get the boiling point yet. -215°C is higher than -220°C, P is also liquid. There are still 5°C until P completely freezes. <em>This is the correct choice.</em>
