Battery acid is acidic in nature so its pH will be more.if we add a base its acidity level decreases and it becomes a poor acid. here water acts as a base to decrease the pH value and acidic nature of a acid substance that is battery acid.
Answer:
sorry friend cant help ya here.
Explanation:
im not rlly that smart :/
it's very practical, because it's on base 10, so conversion between stuff like meters to kilometer is always just a multiplication with 10 to some power
like 1 km = 1000m (10³m)
or 1 m = 10^-3km = 0.001km
same reason for other SI units.
except time, that's base 60, or 12, or 24. that's more complicated, but there isn't any real competition

Cacti or cactuses are member of the plant family and are often referred to as spiny plants that are usually found in the desserts.
Evolution - In biology, is described the ascent or descent in the characteristics of a species over a series of generations
and natural selection favors its modification.
When two species populations evolve to become more similar to each other we say say they have a convergence evolution.
Hint: Evolution of analogous structures is always an example of convergent evolution.
