calculate the equivalent weight of acid on the basis of given reaction. NaoH + H2So4 gives NaHSo4 + H20.

98

Explanation:

Based on the reaction:

NaOH + H2SO4 → NaHSO4 + H2O

Where 1 mole of the base (NaOH) reacts per mole of the acid (H2SO4)

The formula of equivalent weight is:

Equivalent weight = Molecular mass / Number of equivalent moles

Where Molecular mass of sulfuric acid is 98g/mol

And number of equivalent moles = 1 -Because 1 mole of acid reacts per mole of base

Equivalent weight is:

98 / 1 =

98

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
