Chemistry

Answer:

Sulfuric acid

Explanation:

Acid strength (in water) is measured as the equilibria of dissociation of the acid into hydronium and its conjugated base. The greater the Ka value, greater the acid strength.

This equilibrium constant is denominated Ka Ka=\frac{[H+]}{[HA]} where [H+] stands for the molar concentration of hydronium and [HA] stands for the molar concentration of the non-dissociated acid.

The Ka values for these acids are: 1.02x10^{-2} for HClO2; 6.4x10^{-4} for HF; 5.8x10^{-10} for HBO3; 1.2x10^{-2} for H2SO3 and 1.x10^{3} for H2SO4

So, as the greatest Ka is from H2SO4 it is the strongest acid in this list.

Which of the following best explains why you sanded the copper wire before burning it? to create less friction between the coppe
artcher [175]

The copper wire was sanded before burning in order to make sure that copper metal was exposed on the surface of the wire.

Answer: B

Explanation

The copper wire when placed in atmosphere without coating leads to oxidation of copper metal with respect to the impurities present in the atmosphere.

As copper is electropositive in nature, so electronegative ions present in the universe will try to react with copper and the copper will react easily with other elements.

So generally copper wire is coated with color or polymer coating.

In this case, the copper wire without any coating is sanded, so that the eddy sheets or polishing materials on friction with copper wire will remove the impurities by the electrostatic law of conservation of charges and charge transfer.

As the impurities are removed when copper wire is sanded, the copper atoms will be exposed on the surface of the wire leading to burning of copper in the copper wire.
