What are the spectator ions if the following substances are placed in the beaker to react? BaNO3(aq) + Na2SO4(aq)

2NaOH+H2​SO4​→Na2​SO4​+2H2​O= 65/18 = 3.61moles125/142 = 0.88MTotal moles = 4.91H2O = 3.61/4.91 = 0.74Na2SO4 = 0.88/4.91= 0.179

Molar mass of Na2SO4= 142.04 g/mol95.5/142.04= 0.6720.672mol/1.15kg= 0.585mol/Kg

Concentration of the solution in the beaker =1.43M

Probably, you mean the clock reaction. In this reaction amount of KIO3 is crucial. So, we need firstly to pour solution of KIO3 into the volumetric flask and then, well-known...

For the Na2SO4 solution m/v is (63g/260mL)*100%= 24.23% . For a carbonated drink m/v is (38/360)*100% =10.55%

n(NaOH) = 3.50 molesSolution:The equation of a chemical reaction:2NaOH + H2SO4 --> Na2SO4 + 2H2OAccording to the chemical equation: n(NaOH)/2 = n(Na2SO4). n(Na2SO4) = n(NaOH)/2;n(Na2SO4) = 3.50 moles / 2...

The initial solution contains:n = M × Vwhere n - number of moles, M - molarity, V - volume.From here:n = 8 M × 0.4 L = 3.2 molThe final...

Solution:a) Magnesium cloride (MgCl2) is highly soluble in water.In water it dissociates to ions: magnesium ion (Mg2+) and two cloride ions (Cl-).MgCl2(aq) → Mg2+(aq) + 2Cl-(aq)b) Potassium fluoride (KF) is...

According to reactivity series of metals, aluminium is more active. Hence, aluminium will substitute nickel from its salt, while nickel will not substitute aluminium. The answer - nothing will happen...
