Answer:
The alpha particles that were fired at the gold foil were positively charged. ... These experiments led Rutherford to describe the atom as containing mostly empty space, with a very small, dense, positively charged nucleus at the center, which contained most of the mass of the atom, with the electrons orbiting the nucleus.
Answer:
Chemical property
Step-by-step explanation:
When paper burns, it is converted into invisible carbon dioxide and water vapour, plus a little bit of ash.
These are new substances with different properties, so the combustion of paper is a chemical property.

Explanation:
One way to approach this problem is to determine the percent composition of hydrogen in water.
A formula that would represent a solution would be the one that has an (aq) sign. This means that the compound is present in an aqueous solution. Hope this answers the question. Have a nice day. Feel free to ask more questions.
The accompanying depictions show the electron distribution in the H₂O molecule is H : ₊°O°₊ : H.
The chemical formula of water is H₂O,
Electron configuration or electron distribution is the distribution of electrons of an atom or molecule (or other structure) in atomic or molecular orbitals, for example, the electron configuration of a neon atom is 1s²2s²2p⁶. Similarly,
The electronic configuration of O is 1s²2s²2p⁴,
So, it has a total of 6 valance electrons among them 2 are used to make bonds with H and the rest are present as lone pairs.
So, H₂O have two bonded pair of electrons and two lone pair of electrons. And the structure formed is,
H : ₊°O°₊ : H.
