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.

Answer:
Molecular formula: S4K8O16 empirical formula: SK2O4
Explanation:
First we find the moles of each by first finding grams (using the percent) and then using stoichiometry to convert into moles:
Sulfur: 696 *.18 = 125.28grams S*
Potassium: 696 *.4487 = 312.2952 *= 7.99117 mole K
Oxygen: 696 * .367 = 255.432 * = 15.9654 mole O
Then we divide each value by the atom with the smallest number of moles to find the mole ratio:
3.907/3.907= 1
7.99117 mole K/ 3.907= 2.043
15.9654 mole O/ 3.907= 4.08
The empirical formula is SK2O4
To find the molecular formula, we divide the mass given (696) by the mass of the empirical formula (174.22) to get 4. We then divide each atom by 4.
Molecular formula: S4K8O16
Isotopes are the same elements with the same number of portions but different numbers of neutrons
For instance, the element carbon exists as several isotopes, each having the exact same number of protons (otherwise, it would no longer be carbon if the # of protons changes), and a different number of neutrons
Answer:
Explanation:
Hello there!
In this case, since the heat of fusion is a property that allows us to calculate the heat involved during the change from solid to liquid (fusion) and is calculated as shown below:
In such a way, given the heat involved during this process and the mass of copper, we calculate the heat of fusion as shown below:
Or in kJ/mol:
