<h2>Rocks are grouped according to their formation into three major groups – igneous, sedimentary, and metamorphic rocks
</h2>
Explanation:
- Based on their formation, rocks are further sub-grouped as:
- Igneous - Intrusive or extrusive
- Sedimentary – Clastic, chemical, or biologic rocks
- Metamorphic - Foliated and non-foliated
- Rocks are also grouped based on their properties like size, shape, texture, chemical composition, permeability, mineralogy, etc.
- Based on properties rocks are sub-grouped as:
- Igneous rocks – coarse or fine-grained; glassy or obsidian; felsic or mafic.
- Sedimentary rocks - conglomerate, sandstone, breccia, shale, siltstone, chalk, crystalline or fossiliferous limestone, gypsum, rock salt etc.
- Metamorphic rocks - Gneiss, hornfels, mylonites, cataclasties, marble, etc.
Carbon monoxide is a carbon atom bonded with an oxygen atom. Carbon dioxide is a carbon atom bonded with <em>two</em> oxygen atoms. That's it really, they have different properties but that is significantly more detailed and all a result of their molecular formula.
Equation is as follow,
<span> SnCl</span>₂ <span> + PbCl</span>₄<span> </span>→ <span>SnCl</span>₄ <span> + PbCl</span>₂
Oxidation State of Sn on left hand side in SnCl₂ is +2, while that in SnCl₄ on right hand side is +4. Means Sn has lost two electrons. Hence, it is oxidized and has worked as a reducing agent (has reduced Pb from Pb⁺⁴ to Pb⁺²).
Oxidation State of Pb on left hand side in PbCl₄ is +4, while that in PbCl₂ on right hand side is +2. Means Pb has gained two electrons. Hence, it is reduced and has worked as an oxidizing agent (has oxidized Sn from Sn⁺² to Sn⁺⁴).
Answer:
Explanation:
2 NO2(g) ⇄ N2O4(g)
Adding Argon to this reaction will have NO effect. Catalysts nor inert gases have an affect on equilibrium conditions.
Only changes in concentration, temperature conditions and pressure-volume conditions (unless both sides have equal molar volumes) will affect the equilibria.
NH4OH(aq) ⇄ NH3(g) + H2O(l)
Removing ammonia from reaction equilibrium causes the reaction to shift right to replace removed ammonia. => Think of the reaction as being on a seesaw => removing ammonia from the product side tilts the seesaw left causing the NH₄OH to decompose and deliver more NH₃ and H₂O to the product side to increase weight on that side and level the seesaw. :-)
