Aqueous hydrochloric acid will react with solid sodium hydroxide to produce aqueous sodium chloride and liquid water . Suppose 34. g of hydrochloric acid is mixed with 9.30 g of sodium hydroxide. Calculate the minimum mass of hydrochloric acid that could be left over by the chemical reaction. Round your answer to significant digits.

25.51g

Explanation:

We'll begin by writing a balanced equation for the reaction. This is illustrated below:

HCl(aq) + NaOH(aq) —> NaCl(aq) + H2O(l)

Next, let us calculate the molar masses of HCl and NaOH. This is illustrated below:

Molar Mass of HCl = 1 + 35.5 = 36.5g/mol

Molar Mass of NaOH = 23 + 16 + 1 = 40g/mol

From the equation above,

36.5g of HCl reacted with 40g of NaOH.

Therefore Xg of HCl will react with with 9.3g of NaOH i.e

Xg of HCl = (36.5 x 9.3)/40

Xg of HCl = 8.49g

Therefore, 8.49g of HCl was used up in the reaction.

To obtain the left over Mass of HCl, we'll subtract the mass used in the reaction from the mass given from the question. This is illustrated below:

Mass of HCl from the question = 34g

Mass of HCl used in the reaction = 8.49g

The left over mass of HCl = 34 - 8.49

The left over mass of HCl = 25.51g

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
