Metalloids make up the elements that line the line. Both metallic and nonmetallic qualities can be found in them. More electrons are typically gained than lost by the elements to the line's immediate right.

On the periodic table, the nonmetals are to the right of the stair-step line. In chemical processes, metals frequently lose electrons and produce positive ions.

<h3>What is Periodic Table ? </h3>

The chemical elements are shown in tabular form on the periodic table, sometimes referred to as the periodic table of the elements. It is frequently used in physics, chemistry, and other sciences and is frequently regarded as a symbol of chemistry.

<h3>What are Metalloids?</h3>

The term is usually applied to a group of six to nine elements (boron, silicon, germanium, arsenic, antimony, tellurium, and possibly bismuth, polonium, astatine) near the middle of the P block or main block of the periodic table increase.

  • Metals are typically hard, bright, fusible, malleable, and ductile elements with excellent electrical and thermal conductivity.
  • Non-metals are elements that do not have metallic properties. Metalloids are elements with properties intermediate between those of metals and nonmetals.
  • In some cases, these elements are referred to as semimetals.
  • Examples of metalloids include boron, silicon, tellurium, germanium, arsenic, antimony. Others include aluminum, astatine, polonium, etc.

Predict: In each "Climate type" box, Highlight the condition you think will lead to the fastest weathering for the given weather
yanalaym [24]

Answer:

Frost Wedging - Hot and dry

Clay Formation - Cold and Wet

Dissolving - Cold, and dry

Explanation:

The frost wedging happen when the climatic condition is hot and dry. The dry weather compensates the heat and the rock wedging happens quickly. For clay formation the weather has to be cold and wet. The cold weather will make the sand indulge with rock particles resulting in the clay formation.

Calculate the concentration of CO2 in water at 25 degrees Celsius when the pressure of CO2 over the solution is 4.5 atm. At 25 d
OLEGan [10]

Answer : The concentration of CO_2 is, 0.12 M

Explanation :

Using Henry's law :

C_{CO_2}=k_H\times p_{CO_2}

where,

C_{CO_2} = concentration of CO_2 = ?

p_{CO_2} = partial pressure of CO_2 = 4.5 atm

k_H = Henry's law constant  = 3.1\times 10^{-2}mol/L.atm

Now put all the given values in the above formula, we get:

C_{CO_2}=3.1\times 10^{-2}mol/L.atm\times (4.5atm)

C_{CO_2}=0.1395M\approx 0.12M

Thus, the concentration of CO_2 is, 0.12 M

If 0.0714 moles of N2 gas occupies 1.25 L space, how many moles of N2 have a volume of 25.0 L? Assume temperature and pressure s
vfiekz [6]

Answer:

1.428 moles

Explanation:

If 0.0714 moles of N2 gas occupies 1.25 L space,

how many moles of N2 have a volume of 25.0 L?

Assume temperature and pressure stayed constant.

we experience it 0.0714 moles: 1.25L space

x moles : 25L of space

to get the x moles, cross multiply

(0.0714 x 25)/1.25

1.785/1.25 = 1.428 moles
