During an experiment, the percent yield of calcium chloride from a reaction was 82.38%. Theoretically, the expected amount should have been 105 grams. What was the actual yield from this reaction? CaCO3 + HCl → CaCl2 + CO2 + H2O

105.3 grams
101.1 grams
95.6 grams
86.5 grams

86.5 grams

Explanation:

You would do 105 times 82.38% or 0.8238, and you would get 86.49, but you would round up to the nearest tenth which is 86.5,

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
