A. When the substance is in its gaseous state.
<u>Explanation:</u>
When a substance is expanding against its constant volume and pressure, its temperature increases except when the substance is in gaseous state and not in liquid or solid state. So the internal energy increase in the system not only increases and maintaining the volume and pressure of the system remains constant in its gaseous phase. In the first law of Thermodynamics, it is used specifically that to especially in the case of gaseous system.

Answer:
Barium and Chlorine
Explanation:
Ionic bonds are formed between metals and non metals where the metals lose electrons and become positively charged and the non metals gain electrons and become negatively charge. The opposite charges cause them to be attracted to each other and Bond. The only metal in those options above is Barium. Therefore an ionic bond will be formed between Barium and Chlorine.
4. It is an endothermic process. The body of someone taking a shower would be absorbing heat from the environment, another example of this would be cooking an egg
5. Ice melting is endothermic. The ice is absorbing heat from the environment, water freezing would be an exothermic reaction as it is transferring heat into the environment
6 however i do not have an answer for. I may just be a little dense but I'm not entirely sure what it is asking when it asks what the system is.
For the Lewis diagram of the cyanide ion, a
figure is shown.<span>
There are 3 pairs of bonding electrons. There is a
one lone pair each for the carbon and the nitrogen atoms.</span>

Answer:
The correct answer is Option C (E1) and Option B (carbocation).
Explanation:
- Intramolecular immunity idols are considered as that of the formation mechanism with E1 responses or reactivity.
- Reactants with E1 were indeed obligations of both parties, meaning that an E1 reaction was conducted thru all the two stages known as ionization but rather deprotonation. Involves the absence of either an aromatic ring, a carbocation has been generated throughout the ionization solution.
Some other possibilities offered aren't relevant to the procedure outlined. So the above alternative is accurate.
