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.

What mass of al is required to completely react with 25.0 grams of mno2?
horsena [70]
Mass of MnO2 = 25 g 
The reaction would be 3MnO2 + 4Al --> 3Mn(s) + 2Al2O3
 Molar mass of Al = 26.982 g/mol
 Molar mass of MnO2 = 54.938 + 2(15.999) = 86.936 g/mol
 Calculating the moles = 25 / 86.936 = 0.2876 mol.
 Mole ratio MnO2 and Al considering the equation = 3 mol of MnO : 4 mol of Al
 Calculating the moles of Al = 0.2876 mol MnO2 x (4 mol of Al / 3 mol of MnO)
 Number of moles of Al = 0.3834
 Getting the mass in grams as asked = 0.3834 mol x 26.982 g/mol = 10.34 grams.

1. A 1500kg car is being lifted by a hydraulic jack attached to a flat plate. Underneath the plate is
AURORKA [14]

Answer:

the pressure in the pipe in the case when there is no net force on the car is  81,726 N/m^2

Explanation:

a. The computation of the pressure in the pipe in the case when there is no net force on the car is shown below

As we know that

Pressure = F ÷ area

Also

F = mg

Now

= (1500 × 9.8) ÷π (0.24)^2

= 81,726 N/m^2

Hence, the pressure in the pipe in the case when there is no net force on the car is  81,726 N/m^2
