In the reaction of zn with hci, 140.15 g of zncl2 was actually formed, although the theoretical yield
was 143 g. what was the percent yield?

Percent yield of ZnCl₂ = 98 %

Explanation:

Data Given:

Actual yield of ZnCl₂ = 140.15 g

Theoretical yield of ZnCl₂ =  143 g.

percent yield = ?

Solution:

Formula used

          Percent yield = Actual yield / Theoretical yield x 100%

Put values in the formula

           Percent yield = 140.15 g / 143 g x 100%

           Percent yield = 98.007 %

Rounded to significant figure

Percent yield of ZnCl₂ = 98 %

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
