Silicate minerals comprise the most common and abundant mineral group on Earth, silicates.
Answer:
B. 288. G
Explanation:
Moles of Al :
Given, Mass of Al = 20.4 g
Molar mass of Al = 26.9815 g/mol
The formula for the calculation of moles is shown below:
Thus,
The reaction between Al and I is shown below as:
2Al + 3I₂ ⇒ 2AlI₃
2 moles of aluminium react with 3 moles of iodine
1 mole of aluminium react with 3/2 moles of iodine
0.7561 moles of aluminium react with (3/2)*0.7561 moles of iodine
Moles of Iodine = 1.13415 moles
Molar mass of NaOH = 253.8089 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of Iodine = 288 g
Answer:
chemical knowledge
Explanation:
The pursuit of chemical knowledge for its own sake, no set goal Applied chemistry Research that is directed toward a practical goal or application, geared toward a specific goal
Scientific theory's will always change based upon new evidence. The 'Big Bang Theory' is always changing when new evidence arises.
However, on the other hand, scientific laws will never change.
