Answer:
Salt is produced by the reaction of an acid with a base.
Explanation:
A salt consists of the positive ion(cation) of the base and the negative ion (anion) of an acid. The reaction between a base and an acid (neutralisation) leads to formation of a salt.

Explanation:
example: humans (biosphere) can build a dam out of rock materials (geosphere) or water in a lake ( hydrosphere ) seeps into the cliff walls behind the dam becoming ground water ( geosphere) or evaporate into the air ( atmosphere)
Answer:
Fran's upstream time = 37.93 hrs
Fran's downstream time = 30.13 hrs
Explanation:
given data
speed in still water = 2.62 km/h
River flows = 0.3 km/h
Fran to swim upstream = 88 km
solution
we will apply here distance formula that is
distance = speed × time ...................1
put here value
so here
Fran's upstream speed = 2.62 km/h - 0.3 km/h = 2.32 km/h
Fran's downstream speed = 2.62 km/h + 0.3 km/h = 2.92 km/h
so
Fran's upstream time = = 37.93 hrs
Fran's downstream time = = 30.13 hrs
Answer:
because white pieces of paper have a rough surface that means diffused reflection takes place.
