Step-by-step explanation:
(log 0.04 − 2 log 0.3) / (1 − log 15)
<em>Change 1 to log 10.</em>
(log 0.04 − 2 log 0.3) / (log 10 − log 15)
<em>Use log property: a log b = log bᵃ.</em>
(log 0.04 − log 0.09) / (log 10 − log 15)
<em>Use log property: log a − log b = log (a/b).</em>
log (0.04/0.09) / log (10/15)
<em>Reduce fractions.</em>
log (4/9) / log (2/3)
<em>Change 4/9 to (2/3)².</em>
log ((2/3)²) / log (2/3)
<em>Use log property: log bᵃ = a log b.</em>
2 log (2/3) / log (2/3)
<em>Divide.</em>

Answer:
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
balanced equation : 4 Al +3O2 → 2 ALO3
Step-by-step explanation:
Al + O2 → Al2O3
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6
the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.
