The discovery of the atomic nucleus, or perhaps better stated the development of theory of the nucleus, is credited to Ernest Ru

therford in 1911. He was a kiwi physicist who worked in the laboratory of JJ. Tomson, who developed the earlier Plum Pudding model of the atom. A few years earlier, in 1904, Japanese physicist Hantaro Nagaoka postulated the saturnian model of the atom where he envisioned a very heavy positively charged center of the atom with electrons orbiting much like the rings of Saturn. What are the similarities and differences between the Nagaoka and Rutherford models of the atom? If he developed his theory about 7 years earlier than Rutherford, why is Nagaoka not credited with the discovery of the nucleus? Hint: what's a nucleus anyways

Answer:

Both of the studies said that the mass of the atom is centered in the nucleus, which is positive, and there are electrons (negative particles) orbiting it. So, Rutheford and Nagaoka discovered that the atom can be divisible and it has an empty space.

But, in the model of Nagaoka, the nucleus was huge, and for Rutherford, the nucleus was really small, and the mass was concentrated. By his experiment with the gold sheets, the theory was appropriated. That's why Rutherford is credited with the discovery of the nucleus. Nagaoka was incorrect in his suppositions.

Convert 26.02 x 1023 molecules of C2H8 to grams. Round your answer to the hundredths place.
aliina [53]

Answer:

x= 138.24 g

Explanation:

We use the avogradro's number

6.023 x 10^23 molecules -> 1 mol C2H8

26.02 x 10^23 molecules -> x

x= (26.02 x 10^23 molecules  * 1 mol C2H8 )/6.023 x 10^23 molecules

x= 4.32 mol C2H8

1 mol C2H8     -> 32 g

4.32 mol C2H8 -> x

x= (4.32 mol C2H8 * 32 g)/ 1 mol C2H8

x= 138.24 g

How does a difference in 1 pH unit change in terms of H+ concentration? Ex: How does a pH of 3 differ from the pH of 4? Which on
yuradex [85]

Answer:

A difference of 1 would mean there is either x10 more or less depending on where you are starting.

Explanation:

The pH of 3 differs from 4 because the acidity of 3 is 10x higher than that of 4. This is due to how the scientific notation of 3 in relation to pH is 10x^-3 while that of 4 is 10^-4 so in terms of the stronger acid that would be the one with the pH of 3.

Neptune's Triton is being pulled closer and closer to the planet as it orbits. What will likely be a result of this gravitationa
Ksenya-84 [330]

Answer:

the planet's gravity will cause Triton to fly into Neptune

Explanation:

Gravitational force is a force of attraction between two bodies with considerable masses.

One of the mass tends to pull the other to it's center.

As the force of gravity between two bodies grow, the more massive body will be drawn to the other one.

  • The effect is that one body will eventually collide with the other.
  • Since the planet pulls very hard on its moon
  • On the long run, we can expect Triton to fly into Neptune in the foreseeable future.
