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.

An adiabatic throttling valve expands an ideal gas. The internal energy of the ideal gas?
just olya [345]

The internal energy of the ideal gas is zero

The change in internal energy  for an isothermal process is zero.

An ideal gas has no interactions between particles, therefore no intermolecular forces.

pressure change at constant temperature does not change the internal energy.

Adiabatic throttling expansion has less work done and lower heat flow.

That lower the internal energy.

The temperature decreases during the adiabatic expansion

Hence the internal energy of the ideal gas is zero
