The hydronium ion is an oxonium ion whose chemical formula is H3O + or H + (aq). It is found in the solid, gaseous or liquid state (protonation of a molecule of water).
The concentration of hydronium ion is directly linked to the pH of the tea (or any solution) by this equation.:
C° (hydronium) = 10^(-pH)
if the pH of the tea is 6 for example, than:
C° (hydronium) = 10^(-pH) = 10^(-6).
<span>Yes,
there are mammals that lay eggs instead of giving birth to a live young. These mammals
are called Monotremes. One best example to this is the platypus and echidnas.
Platypus, which is also known as the duck-billed platypus, is a semiaquatic
egg laying mammal. Echidnas on the other hand are also called as spiny eaters.
Echidna and platypus are only the surviving members of the Tachyglosside. And are
the sole extant egg laying mammal</span>
The groundwater is being discharged faster than it is being recharged is the data suggested.
Option D

Ground water level is the level of underground storage of water above the impermeable rock layer. The underground water is getting filtered through different layers of permeable rocks before it enters the final layer. So it’s fresh and ready to be consumed as it is taken out. Thus for centuries, it’s being used as the source of drinking water.
But with increasing population, the ground water is being consumed at the rate very faster than it can be refilled from different sources like precipitation, rivers and other water bodies. So its level tends to get lower and lower as this continues until the point it gets finished.
