For which electrode could you use an inactive material
kow [346]

Mercury and carbon two electrodes can't be used with an inactive or inert material.

<h3>What is an electrode?</h3>

The electrode is the element which is used to complete the electric circuit in welding. Some time electrode is connected with the positive terminal and sometimes with a negative terminal, it depends on the requirement of the welding process.

Inert electrode is an electrode that serves only as a source or sink for electrons without playing a chemical role in the electrode reaction. Precious metals, mercury, and carbon are typically used as inert electrodes.

Therefore, neither of the two electrodes can be used with an inactive or inert material.

Specify whether CF4 is polar. Match the correct word in the left column to the blanks in the sentence on the right.
zavuch27 [327]

Answer:

CF4 is non polar

polar, no net, nonpolar

Explanation:

The overall polarity of a molecule depends on the presence of polar bonds within the molecule and the orientation of the polar bonds to produce an overall dipole moment. This implies that the presence of polar bonds in a molecule does not automatically imply that such molecule is polar or will display on overall dipole moment. The orientation of the individual dipoles affects the overall dipole moment of the molecule.

A polar molecule results from an unequal/unsymmetrical sharing of valence electrons. While there may be unequal sharing of electrons in the individual bonds, in a nonpolar molecule like CF4 these bonds are evenly distributed and cancel out. There is no net dipole and the CF4 is non-polar. Hence the order of words chosen in the answer to fill in the blanks.
