An aqueous solution containing both Sr2+ and CO32– ions is mixed in order to precipitate SrCO3(s). given there are 1.40 mL of 2.

53 M Sr2+ ions, calculate the mass of SrCO3 that is formed. assume that all of the Sr2+ ions are consumed. the net ionic reaction is shown below.

First, we calculate the number of moles of Sr2+ ions.

moles Sr = 2.53 M * 0.0014 L

moles Sr = 0.003542 mol

 

There is 1 mole of Sr for every mole of SrCO3, so the moles is equal.

moles SrCO3 = 0.003542 mol

 

The molar mass of SrCO3 is 147.63 g/mol, so the mass is:

mass SrCO3 = 0.003542 mol * 147.63 g/mol

<span>mass SrCO3 = 0.523 grams</span>

How does nuclear fission of Uranium - 234 result in electricity being generated?
nevsk [136]

Answer:

See explanation

Explanation:

The use of Uranium - 234 to generate electricity depends on a fission reaction. The uranium nuclide is bombarded by fast moving neutrons leading to a chain reaction. Control rods and moderators are used to keep the nuclear reaction under control.

As the nuclear reaction proceeds, heat is generated and steam is consequently produced. This steam is used to turn a turbine and electricity is thereby generated.
