queous hydrochloric acid HCl will react with solid sodium hydroxide NaOH to produce aqueous sodium chloride NaCl and liquid water H2O. Suppose 6.93 g of hydrochloric acid is mixed with 2.4 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 2 significant digits. g

Explanation:

NaOH   +   HCl   =   NaCl   +   H₂O

1 mole      1 mole                     1 mole

6.93 g of HCl = 6.93 / 36.5 mole = .19  mole

2.4 g of NaOH = 2.4 /40 mole of NaOH = .06 mole

.06 mole of NaOH  is less than .19 mole of HCl so

limiting reagent is NaOH

.06 mole of NaOH will react with .06 mole of HCl to give .06 mole of water .

water formed by given mass of reactants

= .06 moles of water

= .06 x 18 gram of water

= 1.08 g of water .

= 1.1 g of water .

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
