Hi,
The answer should be letter E, Thomson.

Answer:

Thomson.

Explanation:

J.J.Thomson performed an experiment called cathode ray experiment in which he used a sealed tube fitted with two electrodes.

When a high voltage was applied, the cathodic electrode emitted some particles which moved towards anode. These particles were negatively charged and discovered as electrons.

So he discovered electrons.

Which of the following is not a result when a change to an equilibrium system is applied? Increasing the rate of the forward rea
Scorpion4ik [409]

2) Increasing the rate of the reverse reaction will cause a shift to the left.

Hopefully, If it is wrong my full apologies.



OR IF THATS WRONG, TRY THIS

a - Increasing the rate of the forward reaction will cause equilibrium to be more product-favored (i.e. shift to the right, not the left)

In this experiment you used an excess of the BaCl2 solution. How would your results be affected if you did not use an excess of
Igoryamba

if we did not use an excess of the BaCl2 solution it would decrease the mass percentage of sulfate in the unknown sample.

The net precipitation equation would be.

Ba2+(aq) + SO42-(aq)  → BaSO4(s)

If BaCl2 (Ba2+) is not taken in excess then the precipitation would not be completed as some of the sulfate ions would still be remaining in the solution. This would decrease the mass percentage of sulfate in the unknown sample.

If some tiny pieces of filter paper still remained mixed with the precipitate(BaSO4) then the mass of sulfate would increase and it gives a high mass percentage of the sulfate.

mass percentage of sulfate = (mass of sulfate/mass of sample)*100
