To solve the problem, we need to find two things: the oxidation state of phosphorus in H₃PO₄ and the number of P-OH bonds in the molecule. Let's break it down step by step.Step 1: Determine the number of P-OH bonds in H₃PO₄<
Oxidation: The charge of an element is expressed by its oxidation number. For a neutral element, the oxidation number is zero, and when the element releases an electron, the oxidation number is expressed as positive and when it gains an electron, it is expressed as negative. ...
A natural disaster is an event with a natural, as opposed to human, cause that results in large-scale loss of life or damage to property. It could be related to weather, geology, biology or even factors outside the Earth. Examples are earthquakes, hurricanes, droughts and flooding. Disease...
