Whose model of the atom did J.J. Thomson prove to be incorrect with his Cathode-Ray tube experiments?

Chemistry

Answer:

John Dalton

Explanation:

J.J. Thompson’s cathode ray experiment proved that Dalton’s atomic theory was incorrect,  

Dalton proposed that atoms are indivisible and they are the smallest part of a substance. But Thompson’s cathode ray experiment showed that atoms are made up of negatively charged particles. Option B is correct.

Option A is incorrect. Neils Bohr gave the atomic model after J.J. Thompson and he explained the quantization of electron energy.  

Option C is incorrect. Erwin Schrodinger proposed that electrons move in electron clouds, electrons do not have a definite position and there is a probability of finding electron in space.

Option D is incorrect. James Chadwick discovered the neutron.

JJ Thomson proved John Dalton's theory wrong, as Thomson discovered the electron. This showed that there were particles that were smaller than an atom, despite Dalton claiming that the atom is the smallest unit of matter.

When each of the following pairs of aqueous solutions is mixed, does a precipitation reaction occur? If so, write balanced molec
Aleks04 [339]

Yes, a precipitation process does take place here. BaCO₃ and KOH are the byproducts of this double displacement reaction, and since BaCO₃ is soluble in solution, it precipitates as a solid.

Molecular: Ba(NO₃)₂(aq) + K₂CO₃(aq) → 2K⁺(aq) + 2NO₃¯(aq) + BaCO₃(s) ⬇︎

The complete ionic reaction can be written as follows:

Ba²⁺(aq) + 2NO₃¯(aq) + 2K⁺(aq) + CO₃²¯(aq) → 2K⁺(aq) + 2NO₃¯(aq) + BaCO₃(s) ⬇︎

All the ions in solution have been written out. Now, on to the net ionic equation:

Ba²⁺(aq) + CO₃²¯(aq) → BaCO₃(s) ⬇︎

<h3>what is precipitation?</h3>

Any liquid or frozen water that condenses in the atmosphere and falls to the ground is known as precipitation. Snow, sleet, and rain are just a few of the variations. One of the three main processes that make up the global water cycle is precipitation, along with evaporation and condensation.

Water vapor in the clouds condenses into increasing-sized droplets of water, forming precipitation. Droplets fall to the Earth when they are sufficiently heavy. The water droplets may freeze to produce ice if a cloud is colder, as it would be at higher elevations. Depending on the temperature within the cloud and at the Earth's surface, these ice crystals eventually discharge to the Earth as snow, hail, or rain.

A kernel of popcorn contains a small amount of water and when heated the popcorn pops. How can you explain this to someone
Aliun [14]
When you put a popcorn kernel in a microwave, the microwave heats up the water. The water then evaporates, and the air wants to escape. There will be so much pressure that the skin/shell of the kernel will break, exposing the corn.
