the rate of evaporation equals the rate of condensation.
the rate of condensation decreases to zero.
the rate of condensation exceeds the rate of evaporation.
Explanation:
Evaporation
It is the process of converting liquid into vapors .
Condensation
It is the process of converting vapors back into liquid state .
It is seen that a equilibrium is reached when "rate of evaporation becomes equal to rate of condensation ".
Answer:
Name: Aluminum Sulfite
Explanation:
Systematic nomenclature: dialuminium tris [trioxosulfate (IV)]
Oxoanions: anions derived from removing H + from an oxo acid with a vulgar name:
(SO3)3^-2 (sulfite)
Metal cation according to valence number:
Al (III) or Al+3 (as a cation) (Aluminum)
There are different types of salts, in this case we have a simple salt and the nomenclature for binary substances is used when only one class of cation and one class of anion are present
So:
Al2(SO3)3: Aluminum Sulfite
Ions are charged particles that form when an atom (or group of atoms) receives or loses an electron, and ionic compounds are composed of these charged particles. An anion is a negatively charged ion, whereas a cation is a positively charged ion. Here Al₂(SO₃)₃ is aluminium sulfite.
Ionic compounds are defined as substances that are joined by ionic bonds. In order to reach their closest arrangement as a noble gas, elements can either gain or lose electrons. For the completion of the octet, ions are formed (either by gaining or losing electrons), which aids in their stabilization.
The name of the compound Al₂(SO₃)₃ is aluminium sulfite.

chemical sedimentary rock
The right option is; chemical sedimentary rock
Chemical sedimentary rocks are rocks that are formed by precipitation of minerals from water. Chemical sedimentary rocks are also called evaporates and they are usually composed of the minerals halite (calcium chloride) and gypsum (calcium sulfate). Examples of chemical sedimentary rocks include stalactites, stalagmites, rock salt, flint, and some dolomites.
Answer:
The correct answer is option D, chemical sedimentary rock
Explanation:
Both stalactites and stalagmites are called drip stone as they are formed of the dripping water consisting of minerals. Both stalactites and stalagmites hang up from the ceiling of caves. These are also refereed to as Chemical sedimentary rocks formed by precipitation. The three major processes involved in the formation of these two rocks are –
a) Physical weathering – which disintegrates the minerals contained in the igneous, sedimentary, or metamorphic rock
b) Chemical weathering – which involves dissolution of weathered rock minerals
c) Precipitation of the dissolved minerals.
B. 15 protons, 15 electrons
C. 60 protons, 30 electrons
D. 30 protons, 0 electrons
