Answer:
Rocks are the aggregate of minerals. There are three distinct categories of rocks, namely the sedimentary, metamorphic and the igneous rocks.
- The sedimentary rocks are formed from the deposition, compaction, and lithification of soft sediments that are transported from one place to another by the agents such as wind, water, and ice. For example, Sandstone and Shale.
- The metamorphic rocks are derived from the previously existing sedimentary, igneous or other metamorphic rocks, due to the influence of extremely high pressure as well as temperature conditions. For example, Quartzite and Marble.
- The igneous rocks are those rocks that are formed from the cooling and crystallization of magma. For example, Granite and Diorite.
All these three types of rocks are formed by different processes and their mode of origins are also different.
Answer:
El enlace iónico se da entre dos átomos diferentes (metálico y no. metálico), mientras que el enlace covalente se produce entre dos átomos iguales (no-metálicos). En el enlace covalente hay un compartimiento de electrones, mientras que en el enlace iónico hay una transferencia de electrones
Explanation:
The less dense areas in a sound wave is called a rarefaction or rarefactions if there are multiple.
To answer this question, you need to know the molecular weight of zinc so you can determine how many mol zinc you have. Zinc molecular weight is 65.38gram/mol. Then the calculation would be: 48.3gram/(<span>65.38gram/mol)= 0.74 mol
Since you are asked the amount of atom, you need to multiply the unit in mole with Avogadro number. The calculation should be: 0.74 * 6.02 * 10^23= 4.45* 10^23 molecules</span>
PH = -lg[H+]
pH = -lg[6.38·10-6] = 5.2
