  • Fossils are the preserved remains of organisms that lived several years ago.
  • Fossils are usually found in sedimentary rocks and thick layers of ice in temperate and polar regions.
  • Body fossils are the remains of the body parts of an organism that has been preserved. They can be skeletal parts, teeth, eggs e.t.c

A certain compound is made up of one carbon (c) atom, two bromine (br) atoms, and one oxygen (o) atom. what is the chemical form
padilas [110]
Answer:
           Chemical Formula  =  COBr₂

           Structural Formula  =  Attached Below

           IUPAC Name  =  Carbonic Dibromide

           Common Name  =  Bromophosgene

As we know Carbon has the tendency to form four covalent bonds, Oxygen can form two covalent bonds and Bromine can form a single bond. Keeping this in mind we can say that in given compound carbon is forming two single bonds with two bromine atoms and a double bond with oxygen atom. Therefore, the valencies of all elements in the given compound are satisfied and completed.

Bad White [126]

Answer:

-1043,8 KJ

Explanation:

Hello!

It is necessary to accommodate the reactions to get the reaction of my interest.

Reaction A reverses what modifies its energy in its sign (+72.6 KJ).

Reaction B doubles, which also doubles its energy (-514.4 KJ x 2).

Reaction C reverses what modifies its energy in its sign (-87.6 KJ).

By sum of the energies I get the energy of the global reaction.
