Answer:
4.5 moles of H2O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
C2H5OH + 3O2 —> 2CO2 + 3H2O
From the balanced equation above,
1 moles of C2H5OH reacted to produce 3 moles of H2O.
Finally, we shall determine the number of mole of H2O produced by the reaction of 1.5 moles of C2H5OH. This can be obtained as follow:
From the balanced equation above,
1 moles of C2H5OH reacted to produce 3 moles of H2O.
Therefore, 1.5 moles of C2H5OH will react to produce = 1.5 × 3/ 1 = 4.5 moles of H2O.
Thus, 4.5 moles of H2O will be produced.
If all of the bonding electrons in a molecule are bonded in two-hybrid sp orbitals are likely to have a linear shape.
<h3>What are sp orbitals?</h3>
One of a set of hybrid orbitals is produced when one s orbital and one p orbital is combined mathematically to form two new equivalent, perpendicular orbitals.
A linear molecule is one in which the atoms are arranged in a straight line (less than a 180° angle). The sp hybridization occurs at the central atom of molecules with linear electron-pair geometries.
Carbon dioxide (O=C=O) and beryllium hydride are examples of linear electron pairs and molecular geometry.
Hence, option A is correct.

you find them on a periodic table
Answer:
a rock containing a lot of iron
Explanation:
Iron ore is an ore of iron and this implies a rock that contains a substantial amount of iron.
An ore is a naturally occurring rock type that hosts a certain type of metal or solid that can be won at profit with some gangue minerals. Iron ore is one such type of substance from which significant amount of iron can be extracted for use by man. The remaining part quite not useful is the gangue.
