Answer:
2Al+1.5O2→Al2O3
Thus, 2 mol of Al combine with 1.5 mol of oxygen to form 1 mol of Al2O3.
2 mol of Al corresponds to 2×27=54 g.
Thus, the weight of Al used in the reaction is 54 g.
Answer:
100 °C, because it is the boiling point of water.
Explanation:
The Rock Cycle<span> is a group of changes. Igneous </span>rock<span> can change into sedimentary </span>rock<span> or into metamorphic </span>rock<span>. Sedimentary </span>rock<span> can change into metamorphic </span>rock<span> or into igneous </span>rock<span>. Metamorphic </span>rock<span> can change into an igneous or sedimentary </span>rock<span>. Igneous </span>rock<span> forms when magma cools and makes crystals.</span>
1 mole of NH42SO4 contains 42 moles of H. We take the 42 moles of H and multiply that times Avogadro's number (6.02x10^23) and get 2.5284x10^25 atoms of hydrogen
