Answer:
77.98 g/mol ≅ 78.0 g/mol.
Explanation:
- The molar mass of any compound can be calculated by the sum of the atomic masses of different atoms in the compound multiplied by its no. in the compound.
Molar mass of Al(OH)₃ = (Atomic mass of Al) + 3(Atomic mass of O) + 3(Atomic mass of H)
Atomic mass of Al = 26.98 g/mol. & Atomic mass of O = 16.0 g/mol & Atomic mass of H = 1.0 g/mol.
<em>∴ Molar mass of Al(OH)₃</em> = (26.98 g/mol) + 3(16.0 g/mol) + 3(1.0 g/mol) = <em>77.98 g/mol ≅ 78.0 g/mol.</em>
Answer:
Interphase: the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
Mitosis: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). The major purpose of mitosis is for growth and to replace worn out cells.
Cytokinesis: Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... Mitosis and each of the two meiotic divisions result in two separate nuclei contained within a single cell.
Explanation:
I learned about this and it was pretty confusing. But once you start learning this more, you'll definitely get it! :D
Explanation:
2-methyl pentane
At first, we need to select a long chain.
Then, we should number that chain (Numbering will start from that side from which attachment is closer)
Then, For IUPAC name, at first we write the position at which substituent is attached then, name of subsitent and finally the chain name and suffix.
Here,
position of substituent = 2
name of substituent = -methyl
chain name = pent
suffix = -ane
Then,
IUPAC name is 2-methyl pentane
Hydrothermal metamorphism involves chemical reactions between oceanic lithosphere and warm fluids near mid-ocean ridges
Hydrothermal metamorphism is most common along mid-ocean ridge spreading centers, where warm seawater percolates through hot, cracked basalt. Metamorphism of basalt occurs as a result of chemical interactions between hot saltwater and basalt. On continents, crustal rocks can be metamorphosed by invading, hot fluids associated with igneous intrusions, resulting in hydrothermal metamorphism.
The interaction of a rock with a high-temperature fluid of changing composition results in hydrothermal metamorphism. The compositional mismatch between an existing rock and the entering fluid causes a series of metamorphic and metasomatic processes.
Hydrothermal metamorphism changes Mg-Fe-rich hydrous minerals like talc, chlorite, serpentine, actinolite, tremolite, zeolites, and clay minerals. Hydrothermal metamorphism is frequently responsible for the formation of rich ore deposits.

Answer: Stochiometric coefficients
Explanation: The chemical equations must be balanced to follow the law of conservation of mass which says that the mass of products must be same as the mass of reactants.
This is a skeletal equation and needs to be balanced by adjusting the stochiometric coefficients. In order to keep the mass same, the number of atoms must be same on both sides.
