Answer:
Mass # = Protons + Neutrons= 35
The charge is -1 because 17 protons arent equal to the 18 electrons each has a -1 charge
Explanation:
A Thermochemical Equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH. In variable form, a thermochemical equation would look like this:
A + B → CΔH = (±) #
Where {A, B, C} are the usual agents of a chemical equation with coefficients and “(±) #” is a positive or negative numerical value, usually with units of kJ.

For the calculation of number of moles of HCl
that is produced by 2.73 moles of H₂.
Considering the reaction shown below:
H₂ + Cl₂------->2HCl
This can be seen from the reaction that 1 mole of H₂ produce=2 mole of HCl
So , 2.73 mole of H_{2} will produce= 2.73\times 2 mole of HCl
That is 2.73 mole of H_{2} will produce= 5.46 mole of HCl
So 5.46 mole of HCl will be produced by 2.73 mole of H_{2}
Answer: I think it’s heating the particles in the ethanol caused them to react and bond with gases in the air which carried the liquid ethanol particles around the room
