By looking at the relative positions of the elements calcium, Ca, fluorine, F, sulfur, S, and oxygen, O, in the Periodic Table, which TWO descriptions are TRUE about calcium fluoride, CaF2, and sulfur dioxide, SO2?
CaF2 is an ionic compound, and SO2i is a covalent compound.
CaF2 is formed by covalent bonds, and SO2 is formed by ionic bonds.
CaF2 cannot conduct electricity when dissolved in water, but SO2 can.
CaF2 is a gas at room temperature, while SO2 has a high boiling point.
CaF2 has a high boiling point, while SO2 is a gas at room temperature.
CaF2 is soft at room temperature, while SO2 is hard and forms crystals.
Answer:
Calcium Compunds-The fluoride,CaF²,is important to the production of hydrofluoric acid,Wich is made from CaF² by the action of sulfuric acids.CaF² us used laboratory instruments as a window material both infrared and ultraviolet radiation.

Thus, Since the turn of the 20th century, glass has been made with calcium fluoride, a novel substance. It is a solid that dissolves readily in water and has a special physical and chemical makeup that makes it suitable for usage as a glassmaking material.
Glass used in windows, bottles, and other glass goods was formerly created from calcium silicates before the invention of this substance. The new glass, referred to as glass with added fluorides, has a number of advantages over calcium silicates, which have drawbacks that make them unsuitable for the creation of modern glass.
Calcium Fluorine is a naturally occurring element that is frequently found in rock, soil, plants, and animals.

Jennie observes her brother playing pool and has a theory that the potential energy in the pool stick is transformed into kinetic energy when he hits the ball.
Which explains how she can prove her theory?
A
She could measure the potential energy in the motionless ball on the pool table, and she could measure the potential energy of the pool stick as it moves to strike the ball. These total of these two measurements will be equal to the kinetic energy in the pool ball as it moves, and this proves there was a transformation of energy.
B
She could measure the potential energy when the pool stick is pulled back to strike the pool ball, and then she could measure the kinetic energy in the pool stick as it moves to strike the ball. The potential energy in the pool stick and the kinetic energy in the pool stick should be equal, proving there was a transformation of energy.
C
She could measure the potential energy when the pool stick is pulled back before moving to strike the pool ball, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of kinetic energy and potential energy to prove there was a transformation of potential energy to kinetic energy.
D
She could measure the potential energy of the pool ball when it was sitting on the table, and she could measure the kinetic energy of the ball in motion after the pool stick strikes it. There should be an equal amount of potential energy in the motionless ball and kinetic energy in the ball after the stick strikes it to prove there was a transformation of potential energy to kinetic energy.
