27 gm of Al will react completely with:
`4Al + 3O_(2) rarr 2Al_(2)O_(3)`

27 g of Al will react completely with…… g of O_(2)

27 g of Al will react completely with…… g of O_(2)

27 g of Al will react completely with…… g of O_(2)

Complete the reaction: 4Al + 3O_2 rarr

DeltaH_(f)^(@) for Al_(2)O_(3) is -1670kJ . Calculate the enthalpy change for the reaction :4Al+3O_(2) rarr 2Al_(2)O_(3) .

According to the following reaction, calculate the amount of Al which is required to form 0.5 mole of sodium meta-aluminate. 4Al+3O_(2)rarr 2Al_(2)O_(3)" , "Al_(2)O_(3)+2NaOHrarr 2NaAlO_(2)+H_(2)O

Find our the ratio of coefficients of metals. Al ^ MnO_(2) rarr Al_(2)O_(3) + Mn .
