Answer:

plate tectonics is a scientific theory that describes the large-scale motion of Earth's lithosphere

tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust

Which points of Dalton's atomic theory is supported by these findings?

Sauron [17]

Dalton's Theory:
1. all elements is composed of very small particles called atoms
2. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and properties. 
3. atoms cannot be divided, created, or destroyed
4. Atoms of different elements combine in simple whole number ratios to form chemical compounds 
5. In chemical reactions, atoms are combined, separated, or rearranged.
So as we can see; the first two sentences are correct while the third sentence not supported in the theory

What is the hybridization around the O atom?

baherus [9]

Your answer is......... with little bit explains....and read correctly.......The nitrogen is sp3 hybridized which means that it has four sp3 hybrid orbitals. Two of the sp3 hybridized orbitals overlap with s orbitals from hydrogens to form the two N-H sigma bonds. One of the sp3 hybridized orbitals overlap with an sp3 hybridized orbital from carbon to form the C-N sigma bond. The lone pair electrons on the nitrogen are contained in the last sp3 hybridized orbital. Due to the sp3 hybridization the nitrogen has a tetrahedral geometry. However, the H-N-H and H-N-C bonds angles are less than the typical 109.5o due to compression by the lone pair electrons.

Select the precipitate that forms when aqueous ammonium sulfide reacts with aqueous copper(ii) nitrate. refer to the solubility

natima [27]

Answer:

- The precipitate that forms from the reaction of Ammonium Sulfide and Copper (II) Nitrate is the insoluble Copper (II) Sulfide (CuS).

- Overall ionic equation

2NH₄⁺ + S²⁻ + Cu²⁺ + 2NO₃⁻ → 2NH₄⁺ + 2NO₃⁻ + CuS (s)

- Net Ionic equation

S²⁻ + Cu²⁺ → CuS (s)

Or better written as

Cu²⁺ + S²⁻ → CuS (s)

Spectator ions include 2NH₄⁺ and 2NO₃⁻.

Explanation:

Ammonium Sulfide - (NH₄)₂S

Copper (II) Nitrate - Cu(NO₃)₂

The overall equation for this reaction is a double displacement reaction and the balance form is represented by

(NH₄)₂S (aq) + Cu(NO₃)₂ (aq) → 2NH₄NO₃ (aq) + CuS (s)

Copper (II) Sulfide (CuS) is the insoluble precipitate formed from this reaction.

Note that the compounds in aqueous form are the ones that can allow the existence in ionic form, the insoluble solid compound stays in that form without ionizing, hence, the overall ionic equation is

2NH₄⁺ + S²⁻ + Cu²⁺ + 2NO₃⁻ → 2NH₄⁺ + 2NO₃⁻ + CuS (s)

Then, the ions that occur on both sides of the overall ionic equation, are called spectator ions and they include 2NH₄⁺ and 2NO₃⁻.

These spectator ions can then cancel out, leaving us with the net ionic equation

S²⁻ + Cu²⁺ → CuS (s)

Hope this Helps!!!
