What is one similarity between metals and metalloids?
Arturiano [62]

The correct answer that explains similarities between metal and Metalloids as regards the question is They both conduct electricity

  • Metalloids can be regarded as elements that are  similar to metals, this is because they posses valence orbitals which is described as highly delocalized over macroscopic volumes.

  • As a result of this they can serve as electrical conductors.

  • metalloids posses small energy gap which is located between the valence band as well as the conduction band, as a result of this they are considered as  intrinsic semiconductors when compare to pure conductors like metal.

  • Example of metal is Calcium, sodium and that of Metalloids are silicon and  germanium

Therefore, metal and Metalloids are similar because of their conductivity of electricity

When taking a measurement with a pH meter, keep the instrument in the ______________ until it is needed. Rinse the pH meter with
nydimaria [60]

Answer:

Storage solution; deionized water; stabilizes.

Explanation:

The pH scale measures the concentration of hydrogen ions in acidic and alkaline solutions.

In chemistry, it literally means power of hydrogen ions and it is a measure of the molar concentration of hydrogen ions in a particular solution, thus specifying the acidity, neutrality or basicity of chemical solutions.

Mathematically, the pH of a solution is given by;

pH = -log_{10}(H^{+})

Hence, a solution with a pH of 7 is neutral. Also, a solution with a pH below 7 is acidic but basic (alkaline) if it's pH is above 7.

A pH meter can be defined as a scientific instrument or device designed and developed for the measurement of the hydrogen-ion concentration in water-based solutions, in order to determine their level of acidity or alkanility.

When using a pH meter to take a measurement, you should keep it in a storage solution until it is needed. Also, a deionized water should be used to rinse the pH meter and gently pat dry.

Furthermore, the pH meter should be placed in a given sample solution and a reading of the measurement taken when the pH of the solution stabilizes.
