Calculate the mass of precipitate that will form if 0.75 l of 0.50 m lead nitrate is mixed with 0.850 l of concentrated sodium bromate. ksp for lead bromate = 7.9 x 10-6.

Answer : The mass of formed is 164.4 grams.

Explanation :

The balanced chemical reaction will be,

First we have to calculate the moles of .

From the balanced chemical reaction we conclude that,

Moles of = Moles of = 0.375 mole

The moles of precipitate formed = 0.375 mole

Now we have to calculate the moles of that dissolve in .

The dissociation of lead bromate is written as:

The expression for solubility constant for this reaction will be,

Total volume of the solution = 0.75 + 0.850 = 1.60 L

The moles of that dissolve in = 0.020 mole

The moles of precipitate formed = 0.375 - 0.020 = 0.355 mole

Now we have to calculate the mass of formed.

Therefore, the mass of formed is 164.4 grams.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
