The element that has the fewest valence electrons available for bonding I believe is Hydrogen.
The arrows that represent the phase transitions in which heat energy is gained is : (A). 1, 2 and 3
<h3>Meaning of phase transitions</h3>
Phase transitions can be defined as the changing of matter from one form to another due to the addition or gaining of heat or due to the removal or loss of heat.
Phase transitions in matter are majorly between three phases which are: Solid, Liquid and Gas.
In conclusion, The arrows that represent the phase transitions in which heat energy is gained is : (A). 1, 2 and 3

Answer:
See explanation
Explanation:
In a chemical reaction, a particular reaction path may be favoured due to the fact that it is energetically more favourable(lower energy sigma complex is formed).
The more the resonance structures produced in a particular reaction pathway, the more energetically favourable it is.
In the chlorination of bromobenzene, ortho attack and para attack are preferred because each of these pathways involves a sigma complex with__4________resonance structures. Attack at the meta position involves formation of a sigma complex with only____3_______ resonance structures. The reaction will proceed more rapidly via the_____lower_______ energy sigma complex, so attack takes place at the ortho and para positions in preference to the meta position.
The volume occupied by the given mol of helium gas at the given temperature and pressure is 91.6L.
The Ideal gas Law, also called the overall fuel equation, is the equation of kingdom of a hypothetical ideal gas. It is a superb approximation of the conduct of many gases below many situations, even though it has several limitations.
The precise gas regulation states that PV = NRT, wherein P is absolutely the pressure of a gasoline,volume V is the quantity it occupies, N is the quantity of atoms and molecules inside the fuel, and T is its absolute temperature.
Given;
Amount of helium n = 2.59 mole
Pressure p = 0.826 atm
Temperature T = 356 K
The volume of Helium = ?
PV = nRT
V = nRT/P
V = 2.59 mole * 0.826 atm * 356K/0.826
V = 75.6626/0.826
V = 91.6 L
