Chegg Aqueous hydrobromic acid will react with solid sodium hydroxide to produce aqueous sodium bromide and liquid water . Suppose 17.0 g of hydrobromic acid is mixed with 14. g of sodium hydroxide. Calculate the minimum mass of hydrobromic acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.

0 grams as HBr is the limiting reagent and gets completely consumed.

Explanation:

To calculate the moles :

According to stoichiometry :

1 mole of require = 1 mole of

Thus 0.210 moles of will require=  of

Thus is the limiting reagent as it limits the formation of product and is the excess reagent.

Thus no mass of hydrobromic acid that could be left over by the chemical reaction

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
