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.

Give the ion symbol for the ion that has 27 protons and 24 electrons.
Natalija [7]

Answer:

Z³⁺

Explanation:

The ion symbol can be depicted as Z³⁺ .

In this atom, the number of protons is 27 and the number of electrons is 24.

Protons are the positively charged particles within an atom.

Electrons are the negatively charged particles within an atom.

 To find the charge;

   Charge  = Number of protons  - number of electrons

  Charge  = 27   - 24  = +3

The atom is positively charged and it can be depicted as Z³⁺

At which of the following temperatures is the average kinetic energy of the molecules of a substance the least? 23.2 °C 35.2 °C
svp [43]
At 15.2°C. Kinetic energy of molecules highly depends on the temperature — the warmer it is, the faster the molecules will move, especially in fluids (gases and liquids). If we consider that the formula for average kinetic energy of molecules is:

Ek = 3/2*k*T where k is Boltzmanns constant and 3/2 is, well, 3/2, kinetic energy of molecules really only depends on the temperature.
