What is the formula for the ionic compound that is formed from aluminum and oxygen?
aluminum oxide AlO3
Given the incomplete equation 4Al plus 3O2 2X what compound is X?
The aluminium oxide is AlO3.
What is the symbol for aluminum trioxide?
AlO3
Which of following solids would hae higher melting point AlO3 vs NaBr?
Aluminum oxide (Al2O3) would have a higher melting point than sodium bromide (NaBr). This is because aluminum and oxygen ions in Al2O3 are more strongly bonded through covalent bonds, while sodium and bromide ions in NaBr are held together by weaker ionic bonds. Stronger bonding requires more energy to break, resulting in a higher melting point.
What properties does granite have?
The density of granite is between 2,65 g/cm3 and 2,75 g/cm3; the melting point is in the range1 215-1 260 oC. Granite is formed from SiO2, AlO3, K2O, Na2O, CaO, etc. Because granite contain uranium and thorium in traces has a natural radioactivity.
What is the equation for iron III oxide plus aluminum yields aluminum oxide and iron?
Fe2O3 + 2Al --> Al2O3 +2 Fe The reaction is commonly known as thermite for the enormous amount of heat produced. The iron produced by the reaction is molten.
