Answer:
There are 6.022 × 10²³ atoms in one molecule of aluminium
Answer: Heterogenous mixtures are the ones in which we can see the different components clearly. Air is considered to be homogenous, because we don't see the different noble gases' particles floating around. Salt water is also homogenous, because salt dissolves almost completely into water, becoming hard to see without the proper equipment salt particles in it. Steel is also homogenous, since the metals that compose it are mixed during the heating. The only heterogenous would be soil, because we can see different particles in it, with different sizes, shapes, colors, etc without having to use special equipment.

<span>the answer:
The net ionic equation,
H3PO4 (aq) + 3 OH− (aq)------- PO4−3 (aq) + 3 H2O (l),
</span> H3PO4 is a strong acid, (presence of hydrogen H)
OH- is a strong base, (presence of OH-)
so the true answer is <span>strong acid-strong base</span>
