HClO4 is stronger acid than HClO? Give reason

mamaluj [8]

HCIO4 is a stronger acid than HCIO because as the number of oxygen increases the oxidation number in the central atom increases which weakens the O-H bond strength and increases the acidity.

Which equation is used to calculate the electric potential in an electric field from a point charge?

scZoUnD [109]

Answer:

The electric potential (voltage) $V$ produced by a point charge $Q$ , at any point in space, is given by the following equation:

$V=k\frac{Q}{r}$

Where:

$k=8.99(10)^{9} Nm^{2}/C^{2}$ is the Coulomb's constant

$r$ is the distance

The result is a scalar quantity, is defined as the electric potential energy per unit of charge and determines the electric influence exerted by the charge on that point of space.
