Answer:

There are two explanations to this: covalent network bonding and carbon-silicate cycle.

Explanation:

A network solid or covalent network solid is a chemical compound which is formed through a continued network of atoms or molecules held together by a covalent bond throughout the system. An example included C-C bond in graphite or C-Si bond in silicon carbide (tentative reaction equation below):

xSiO2 + yCO2→ SixCyO(2x+2y)

Si-Si bonds are not as strong as C-C bonds and can easily be displaced as the particles react with atmospheric CO2.

The second scenerio is when silicates such as calcium silicate CaSiO3, or wollastonite, reacts with atmospheric carbon dioxide and water to yield a calcium ion, Ca2+, a bicarbonate ion, HCO3-, and dissolved silica. This process occurs during carbon-silicate cycle and increase organic carbon content:

2CO2 + H2) + CaSiO3 → + SiO2CaCO3 + CO2 + H2)

Please help! If a forensic chemist discovers evidence through examination which would prove a person guilty of a crime, why then
Bogdan [553]

Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.

I hope this helped :) If not i'm sorry!

Two solid blocks are HEATED to the temperatures show. The blocks are placed so they touch. Which diagram shows the DIRECTION HEA
Setler [38]

Answer:

Heat flows from the block at high temperature to the one with lower temperature

Explanation:

The direction of heat flow is from a body at higher temperature to one with a lower temperature.

  • Temperature gradient determines the way and manner in which heat is dissipated.
  • As a system tend to increase entropy, it ensures that heat moves from hotter body to a colder body.
  • Heat movement here is by conduction as the body touches.
  • When both bodies reaches the same temperature, thermal equilibrium is established.

What type of bond forms between two oxygen atoms
mr_godi [17]

Answer:A double convalescent bond is where two pairs of electrons are shared between the atoms rather than just one pair. Two oxygen atoms can both achieve stable structures by sharing two pairs of electrons as in the diagram.

Kitty [74]

Answer:

All elements are neutral

Explanation:

The plum pudding model of the atom indicated that all elements are neutral. The model was proposed by J.J Thomson after he conducted his experiment on the gas discharge tube.

From the experiment he discovered electrons which he called cathode rays.

Therefore, he suggested the plum pudding model of the atom.

The model describes negatively charge sphere surrounded by positive charges to balance them.
