Q

A carbon atom bonds with four different hydrogen atoms to form the molecule methane. The carbon and the hydrogen atoms stay close together so that, collectively, they have full electrons shells as electrons are able to fill a spot in a shell of more than one atom. What kind of bond does this describe?

Ionic

Covalent

Hydrogen

A

Covalent

17
Q

If two atoms both lose one electron each, will they form an ionic bond with each other?

No, because they will have the same charge.

Yes, because charged atoms form ionic bonds.

No, because their electron shells will be full.

Yes, because atoms bond together ionically.

A

No, because they will have the same charge.

24
Q

If the plant gets too dry, the water column can break. This creates an air bubble in the xylem.

What happens to the water when the air bubble forms?

The pressure of the air bubble forming will force the water to spring back into a continuous column.

The water is still adhering to the xylem walls, but the water column is no longer continuous.

Nothing will happen. Water can travel through the air bubble and maintain the same continuous stream as before.

There is no longer anything holding the water in the tube, so it will collapse down to ground level.

A

The water is still adhering to the xylem walls, but the water column is no longer continuous.
