There are several different rocks that are formed in this manner, depending upon the makeup of the lava. You are probably looking for one of these three answers:
pumice
scoria
vesicular basalt
This is the description of a volcanic eruption.A eruption.
A volcano is called a volcano whether it is erupting or not.It is called an active volcano if it is erupting or has erupted recently.It is a dormant volcano if it hasn't erupted in a long time.Extinct volcanoes are not expected to ever erupt again.
No, Volcanic gas is the gaseous component released by a volcano, composed primarily of water vapor, carbon dioxide, and sulfur dioxide. Fine particles of volcanic rock produced by some eruptions are called ash, not gas.
A rock with little to no grain development and a vesicular texture is typically called a vesicular rock. It is formed from a volcanic eruption, where gases trapped in the lava create bubbles or vesicles. The most common example is vesicular basalt.
It is called "carbonation" because the bubbles are CO2, carbon dioxide.

Yes they are. A volcano that is not erupting is called a dormant (meaning sleeping) volcano, while one that is erupting is called an active volcano.

It is called a bubble wand.
Volcanic rocks with gas bubbles are called vesicular. This, however, is a descriptive term rather than an actual rock types. Some vesicular volcanic rocks include pumice, scoria, and vesicular basalt.

An extrusive rock is a rock that has been deposited at the earths surface as a liquid/fluid, coming to the surface form a depth through a fissure in the earth as a liquid/fluid. The most common type of liquid rock is a magma and magmas erupting at the surface are called "volcanoes" and thus the rocks are called "volcanic" rocks. However there are also volcanoes to be found that have nothing to do with molten rock magmas. These are called "Mud" volcanoes and they are caused by de-watering processes in rocks. The muds brought to the surface are also technically extrusive and these are NOT volcanic rocks.
It is called "carbonation" because the bubbles are CO2, carbon dioxide.
