A reaction mixture initially contains 0.236 mol FeS and 0.670 mol HCl. Once the reaction has reached completion, what amount (in moles) of the excess reactant is left

Answers

Answer:

= 0.198 mole H₂S in excess

Explanation:

A quick way to determine limiting reactant is to convert reactant values given to moles and divide by respective coefficient. The smaller value is the limiting reactant other reactants will be in excess. However, when working problem, use mole values given to solve, not results of division.

       FeS         +        2HCl          => FeCl₂ + H₂S

0.236mole/1      0.670mole/2

   = 0.236             = 0.335

limiting reactant is FeS; HCl will be in excess.

Problem solution

0.236mole FeS used + 2(0.236 mole HCl used)

=> 0.236 mole FeCl₂ + 0.236 mole H₂S + (0.670 - 0.472) mole HCl in excess or, 0.198 mole H₂S in excess.

Hope this helps.    :-)

What’s the frequency of radiation that has a wavelength of 13 um, about the size of bacterium?

Answers

Answer:

2.3)X10^13-Hz

Explanation:

What’s the frequency of radiation that has a wavelength of 13 um, about the size of bacterium?

a micro meter is 10^-6 meter

frequency of light times wavelength = c  the speed of light 3X10^8 M/sec

so

frequency times 13 X10^-6 =3X10^8  M/

so

FR3EQUENCY = 3X10^8/13X10-6

=(30/13)10^13 =2.3)X10^13-Hz

(e) alkaline earth element with the least massive atoms​

Answers

Hopefully this helps you

The alkaline earth element with the least massive atoms is beryllium (Be). Beryllium, located in Group 2 of the periodic table, possesses the lowest atomic number and atomic mass within the alkaline earth elements.

Among the alkaline earth elements, which are found in Group 2 of the periodic table, beryllium (Be) stands out for having the least massive atoms. The periodic table is organized in a way that elements are ordered by increasing atomic number, which corresponds to the number of protons in an atom's nucleus. For alkaline earth elements, the atomic numbers increase from beryllium (Be) with atomic number 4 to radium (Ra) with atomic number 88.

Atomic mass, on the other hand, takes into account the sum of protons and neutrons in an atom's nucleus, as electrons contribute very little to the overall mass. Since beryllium (Be) has the lowest atomic number in the alkaline earth group, it also has the fewest protons and neutrons among its isotopes, leading to a lower atomic mass compared to other elements in the same group.

Relate microscopic bonding properties to solid state properties

Answers

There are many factors that we can take into account when attempting to relate microscopic bonding properties to solid-state properties, for example, the rigid and immobile nature of solid states and their molecular bonds.

Solid-state properties are simply put, the properties we can observe and measure when studying an element in solid form. These solids have specific characteristics such as:

Structural rigidityThey do not change shapeDo not change the volume they occupy

and so on, which although not initially obvious, are caused by the microscopic molecular bonds of their atoms.

The microscopic properties of solids are very similar to that of the solid-state properties. The atoms of a solid are very close together and strongly bonded to one another, because of this the atoms form a very rigid structure that resists changes to their shape or volume, much like the macroscopic properties of the solid. This serves to show how these properties may cause the solid-state effects we can observe normally.

Answers

Answer:

Before we can sketch the Lewis structures of molecules, we must first understand the octet rule. The octet rule asserts that when atoms combine to create compounds, electrons are gained, lost, or shared among them, resulting in a stable electron configuration defined by eight valence electrons as a result. These rules are used in conjunction with the main-group components of the second period.

I am convinced that this government is so constituted that the representatives will generally be composed of the first class in the community, which I shall distinguish by the name of the natural aristocracy, of the country.In every society, men of this [aristocratic] class will command a superior degree of respect; and if the government is so constituted as to admit but few to exercise the powers of it, it will, according to the natural course of things, be in their hands.
