Gaseous dichlorine monoxide decomposes readily to chlorine (green) and oxygen (red) gases.
Alja [10]

Chemical symbols are represented with their coefficients in a balanced reaction. Ethane and oxygen are the reactants, whereas carbon monoxide and water are the products.

4 HCl (g) + O₂ (g) → 2 Cl₂ (g) + 2 H₂O (l)

<h3>What is Carbon monoxide?</h3>

Carbon monoxide, a colorless, incredibly lethal, odorless, tasteless, and flammable gas with the chemical formula CO, is a little less dense than air. Carbon monoxide is a compound made composed of one carbon atom and one oxygen atom joined by three bonds. This is the simplest molecule in the oxocarbon family. The term "carbonyl" refers to the carbon monoxide ligand in coordination complexes. It is an essential part of many industrial chemistry procedures.

Carbon monoxide plays important biological roles in all phylogenetic kingdoms.

Answer:

  1. Compress
  2. Fixed
  3. Melts
  4. Melting Point
  5. Freezing Point
  6. High
  7. Crystalline
  8. Lattice
  9. Unit cell
  10. Amorphous solids

Explanation:

Solids tend to be dense and difficult to <u>compress.</u>

They do not  flow or take the shape of their containers, like liquids do, because  the particles in solids vibrate around <u>fixed</u> points.

When a solid  is heated until its particles vibrate so rapidly that they are no longer  held in fixed positions, the solid <u>melts</u>.  

<u>Melting point</u> is the  temperature at which a solid changes to a liquid. The melting and <u>freezing point</u>  of a substance are at the same temperature.

In general,  ionic solids tend to have relatively <u>high</u>  melting points, while  molecular solids tend to have relatively low melting points.

Most  solids are <u>crystalline</u>

The particles are arranged in a pattern known  as a crystal <u>lattice</u>

The smallest subunit of a crystal lattice is the <u>unit cell</u>  

Some solids lack an ordered internal structure   and are called <u>amorphous solids.</u>

What is carbon fixation? carbon atoms are joined with oxygen molecules to make carbon dioxide carbon atoms are added to molecule
Sidana [21]

Carbon fixation is the process of conversion in which carbon-dioxide (inorganic carbon) converts into organic compounds with the help of living organisms and example of this process is photosynthesis.

From the definition, it is confirmed that there is no formation of carbon dioxide takes place i.e. carbon doesn't joined with oxygen molecules.

Thus, carbon fixation is the process in which carbon atoms are added to the molecules of hydrogen and oxygen to make carbohydrates.

frez [133]
M1 * v1 = m2 * v2 
<span>2.50 * v1 = 1 * 75 
</span>2.50 * v1 = 75
2.50 * v1 /75= 75/75
<span>v1= 30 ml
