Answer:
i dont know what you're asking here. But if you're asking what it is then:
Explanation:
Aluminum Hydroxide + Hydrogen Chloride = Aluminum Chloride + Water
Al and Oh3: Aluminum Hydroxide
H and Cl: Hydrogen Chloride
Al and Cl3: Aluminum Chloride
H2O: water
btw the first letter of every element should be capitalized. While the second and theird are lowercased.
The statement that is true among
the following sentences is ‘Minerals can be elements or compounds’. Minerals cannot
be liquid in form and they are not organic. Minerals are inorganic and present
as solid in phase. When placed in water, they do not dissolve at all.
Answer:
However, when formal units are used to measure length, the measurement can usually be read from a scale on a ruler or tape, which shows units of a particular size. Unit iteration involves knowledge of repeatedly placing identical tightly packing units so that there are no overlaps or gaps.
Explanation:
Answer : 6.41 moles of silicon are in the sample.
Solution : Given,
Moles of magnesium = 9.62 moles
The given chemical formula for talc is, 
From the given chemical formula we conclude that
The stoichiometry of magnesium and silicon is 3 : 2
3 moles of magnesium is equivalent to 2 moles of silicon
9.62 moles of magnesium will be equivalent to 
moles of silicon
Therefore, the number of silicon present in sample are 6.41 moles.

melts an ore to separate useful metals from the rest of the elements in the ore
is called smelting. The ore is heated beyond its melting point to extract the
metal with the help of oxidizing agents such as air or reducing agents such as
coke. </span>
