<h2>Answer :2PbSO4 → 2PbSO3 + O2 </h2>
Answer: Employments of friction based electricity incorporate contamination control, Xerox machines, and painting. They utilize the property that inverse electrical charges pull in. There are different utilizations including the properties of aversion and the making of electricity produced via friction flashes
friction based electricity is an awkwardness of electric charges inside or on the outside of a material. The charge stays until it can move away through an electric flow or electrical release.
In view of similar kinds of examinations like the one you performed, researchers had the option to set up three laws of electrical charges: Inverse charges pull in one another. Like charges repulse one another. Charged items pull in nonpartisan articles.
Answer: A weak acid solution consists of mostly nonionized acid molecules.
Explanation:
Strong electrolytes are those solutions which undergo complete dissociation when dissolved in water. The dissociation of strong electrolytes is given by a right arrow.
Weak electrolytes are those solutions which do not undergo complete dissociation when dissolved in water. The dissociation of weak electrolytes is given by a rightleft arrow.
Weak acids are those substances which dissociate partially to give
ions when dissolved in water. Thus most of molecules remain unionized in solutions.

Strong acids are those substances which dissociate completely to give
ions when dissolved in water.

HClO, perchloric acid is a weak acid. Unlike strong acids like HCl or H2SO4 it not dissociate completely but partially such that an equilibrium exists between the dissociated ions and the undissociated acid. The equilibrium is as shown below:
HClO + H2O ↔ H3O⁺ + ClO⁻
Since HClO is a weak acid, the reverse reaction is favored over the forward reaction. Thus apart from water, HClO will be present in large amounts.
