Which answer choice best describes why the results of Ernest Rutherford's gold foil experiment led him to propose the concept of

a nucleus? A.) The positively charged alpha particles were deflected more often than expected, which indicated that the gold atoms' negative charges were located at the center of each atom. B.) The positively charged alpha particles were deflected less often than expected, which indicated that the gold atoms' negative charges were not evenly distributed throughout each atom. C.) The positively charged alpha particles were deflected less often than expected, which indicated that the gold atoms' positive charges were located around the outside of each atom. D.) The positively charged alpha particles were deflected more often than expected, which indicated that the gold atoms' positive charges were not evenly distributed throughout each atom.

<h3><u>Answer;</u></h3>

D.) The positively charged alpha particles were deflected more often than expected, which indicated that the gold atoms' positive charges were not evenly distributed throughout each atom.

<h3><u>Explanation</u>;</h3>
  • <em><u>During the experiment, alpha particles bombarded a thin piece of gold foil. The alpha particles were expected to pass easily through the gold foil. Every now and then, however, an alpha particle bounced back- an unexpected result. Rutherford concluded that these particles were striking a tiny region of positive charge.</u></em>
  • The discovery of the nucleus was a result of Rutherford's observation that a small percentage of the positively charged particles bombarding the metal's surface were deflected back towards the source.
  • He concluded that each atom contained a very small, very dense, positively charged center which he called the nucleus.

Answer:

D

Explanation:

The positively charged alpha particles were deflected more often than expected, which indicated that the gold atoms' positive charges were not evenly distributed throughout each atom.

sucrose is composed of carbon hydrogen and oxygen which of the following is not needed in order to determine the precent by mass
Dimas [21]

Explanation:

It is often desirable to determine the mass percent of elements in a given compound.

To determine the mass percent of elements:

  • Evaluate the formula mass of the compound. This is done by summing the atomic masses of the atoms in the compound together.
  • The mass percentage is determined by pacing the mass contribution of each element or group to the formula mass of the compound and multiply by 100.

Label the signals due to ha, hb, and hc in the 1h nmr spectra.
trapecia [35]
Structure along with ¹H-NMR is shown below.

Signal for Hₐ;
                     Based on multiplicity of of the peak, a Singlet peak (the only singlet peak present in spectrum) at 2.2 ppm was assigned to Hₐ. As the methyl group in not coupling with any other proton so it gave a singlet peak.

Signal for Hb;
                     Based on multiplicity of of the peak, a Quartet peak (the only quartet peak present in spectrum) at 2.4 ppm was assigned to Hb. As the methylene group in coupling with methyl group having three protons so it gave a Quartet peak.

Signal for Hc;
                     Based on multiplicity of of the peak, a Triplet peak (the only triplet peak present in spectrum) at 1.1 ppm was assigned to Hc. As the methyle group in coupling with methylene group having two protons so it gave a Triplet peak.
