Answer:

There is a positive charge in the nucleus

Explanation:

The concept was envisaged by Ernest Rutherford. He was a renowned scientist and chemist. In the hypothesis, he proposed that an atom must have a concentrated positive charge around the nucleus or in the nucleus that contains the atom's mass. He also suggested that the nucleus contains a particle with a positive charge that was called a proton.

When a neutral hydrogen atom loses an electron, and positively-charged particles should remain. A proton should be 1840 times heavier than an electrons. Cathode rays should be attracted to a positively- charged plate.

Explanation:

Pure Gold is an element.

An element is a distinct substance that cannot be split-up into simpler substances. Such substances consists of only one kind of atom.

There are over a hundred elements known to date.

As an element, Gold is classified as a metal due to its very unique set of properties.

One of the indicator that gold does not react with oxygen is that it stays shiny. It does not give rusty look when exposed to air.

Substances that combines with oxygen have a rusty look or change appearance when expose to air. For example, iron.

How many moles of S are in 35.4 g of (C3H5)2S?
alexandr402 [8]
<span>0.310 moles First, look up the atomic weights of the elements involved. Atomic weight carbon = 12.0107 Atomic weight hydrogen = 1.00794 Atomic weight sulfur = 32.065 Molar mass (C3H5)2S = 6 * 12.0107 + 10 * 1.00794 + 32.065 = 114.2086 g/mol Moles (C3H5)2S = 35.4 g / 114.2086 g/mol = 0.309959145 mol Since there's just one sulfur atom per (C3H5)2S molecule, the number of moles of sulfur will match the number of moles of (C3H5)2S which is 0.310 when rounded to 3 significant digits.</span>
