Making observations is the first step in the scientific method. Why don't scientists stop with the first step when creating an e

xperiment?
A. Scientists don't stop with the first step of their experiment because they don't think that just using their observations is a very good place to start to prove their hypothesis.
B. Scientists don't stop with the first step of their experiment because they not only want to observe but they want to test their observations to be sure they are correct.
C. Scientists don't stop with the first step of their experiment because they want other scientists' opinions because they may not trust their own observations.
D. Scientists don't stop with the first step of their experiment because they would rather plan and run experiments than just observe the world around them.

Describe the experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom.
svetlana [45]

Explanation:

Rutherford conducted an experiment in which he took a thin gold particle film on which he passes alpha- particles. He noticed that:

  • Most of the alpha particles get through the film and can be detected by the detector.
  • Around small portion of the alpha particle deflected at small angles.
  • A very very few alpha particle (approximately 1 out of 1 million alpha particles) just retraced their path which means come back from the center.

He concluded that:

<u>Most of the space of the atom is empty and in the center of the atom , there is solid mass which is the cause of the alpha particles to come back. He gave the term nucleus to this solid mass.</u>

Which species acts exclusively as spectator ions in this reaction
adelina 88 [10]

Answer:

K^+ and NO3^-

Explanation:

In a balanced ionic equation, we usually see the species that react to yield the main product in the reaction.

Consider the reaction;

Pb(NO3)2(aq) +2 KI(aq) -------> PbI2(s) + 2KNO3(aq)

The main product in this reaction is PbI2. Hence the balanced ionic equation is;

Pb^2+(aq) + 2I^-(aq) ------> PbI2(s)

Notice that K^+ and NO3^- did not participate in this reaction. All ions that are part of the molecular equation but do not participate in the ionic reaction equation are called spectator ions. Hence K^+ and NO3^- are spectator ions in this reaction as can be seen clearly above.
