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.

How many moles of KOH are required to produce 4.79 g K3PO4 according to the following reaction? 3KOH + H3PO4 -----&gt; K3PO4 + 3
8_murik_8 [283]

Answer:

0.677 moles

Explanation:

Take the atomic mass of K = 39.1, O =16.0, P = 31.0

no. of moles = mass / molar mass

no. of moles of K3PO4 used = 4.79 / (39.1x3 + 31 + 16x4)

= 0.02256 mol

From the equation, the mole ratio of KOH : K3PO4 = 3 :1,

meaning every 3 moles of KOH used, produces 1 mole of K3PO4.

So, using this ratio, let the no. of moles of KOH required to be y.

\frac{3}{1} =\frac{y}{0.02256} \\

y = 0.02256 x3

y = 0.0677 mol

If you don't find exactly 0.677 moles as one of the options, go for the closest one. A very slight error may occur because of taking different significant figures of atomic masses when calculating.

Why is enthalpy important?
belka [17]
The Law of Conservation of Energy states that, within a closed system, the total amount of energy remains constant. However, energy may change from kinetic to potential and vice versa. The total energy will not have changed. <span>Enthalpy is a measure of the amount of energy that exists in a system at constant pressure. </span>
