Where do the gaseous elements tend to be located on the table

kotegsom [21]

Answer:

Group 8 or Group 0

Explanation:

Group 8 or Group 0 are generally inert gases with Helium as the first member in that group. Their complete duplet (in the case of Helium) and Octet (in the case of Neon) configuration makes them very stable and chemically un-reactive.

Calculate the mass of 0.0455 mol of Ni

Lera25 [3.4K]

Answer:

2.67g Ni

Explanation:

To convert from moles to mass, use molar mass as a conversion factor.

Nickel has a molar mass of 58.69g/mol.

0.0455mol ( $\frac{58.69g Ni}{1 mole Ni}$ ) = 2.67g Ni

At high temperatures, sulfur combines with iron to form brown-black iron(II) sulfide:

taurus [48]

The percent yield : 79.9%

<h3>Further eplanation </h3>

Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

Fe(s)+S(s)⇒FeS(s)

The reaction produces 6.29 g of iron(II) sulfide⇒an actual yield

The maximum amount that can be produced is 7.87 g ⇒ A theoretical yield

$\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\\%yield=\dfrac{6.29}{7.87}\times 100\5=79.9\%$

A low-melting crystalline compound that does not conduct electricity in the solid or liquid state is classified as a ________ so

iogann1982 [59]

These characteristics are possessed by molecular solids. Examples of molecular solids are hydrocarbons. The atoms are bonded by relatively weak intermolecular forces like dipole forces. Hence, they easily melt. When dissolved in water, they don't dissociate and form ions unlike ionic solids. Therefore, they don't conduct electricity whether in solid or liquid form.
