18.1g

Explanation:

Given parameters:

Number of moles of SO₂ = 0.567moles

Unknown parameters:

Mass of Sulfur = ?

Solution:

The reaction equation is given below:

S + O₂ ⇒ SO₂

To solve this problem, we work from the known to the unknown. This suggests that we use the number of moles of the product to work the mass of the sulfur.

From the reaction equation,

1 mole of SO₂ is produced by reacting 1 moles of S

0.567moles of SO₂ will be produced by 0.567moles of S

Since we know the number of moles of the reactant, we can find the mass of sulfur now:

Mass of sulfur = number of moles of sulfur x molar mass of sulfur

Molar mass of S = 32g/mol

Mass of sulfur = 0.567 x 32 = 18.1g

Why do vinyl raincoats become brittle as they get old, even if they are not exposed to air or to any pollutants

Leto [7]

Answer:

The substances made from polyvinyls are generally brittle and hard. This property prevails because the polymer strands present in the polyvinyls form a very regular and well-organized packing composition in the solid-state. The Van der Waals associations between the strands make the substance brittle. To make the substance soft and suitable to use as a raincoat, the incorporation of small molecules is done within the molten polymer before the hardening of the plastic.

These polymer strands act as plasticizers and prevent the strands of polymer from forming a hard and brittle conformation.

The ionization energies (kJ/mol) of hydrogen, nitrogen, sodium, chlorine, and fluorine are 1,312, 1,402, 496, 1,256, and 1,681,

Norma-Jean [14]

Answer: Sodium will most likely to become a monoatomic ion with fluorine when these atoms interact.

Explanation:

Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.

With increase in atomic size of the atom, there will be less force of attraction between the nucleus and the valence electrons of the atom. Hence, with lesser amount of energy the valence electrons can be removed.

More is the value of ionization energy more it is difficult to remove an electron. Therefore, lesser is the reactivity of element.

Hence, we can conclude that sodium will most likely to become a monoatomic ion with fluorine when these atoms interact.
