Applying 1st law of thermodynamics:
Q = Delta U + WB
WB is the workdone by the system
<span>WB = 346 J </span>
As,
<span>Delta U = ( m ) ( CV ) ( T2 - T1 ) </span>
<span>CV = ( Delta U ) / ( m ) ( T2 - T1 )
</span>Putting the values in equation:
<span>CV = ( 8485 J ) / ( 80.0 g ) ( 225 C - 25 C ) </span>
<span>CV = 0.5303 J / g - C degree </span>
Now putting in original equation:
<span>Q = Delta U + WB </span>
<span>Q = ( 8485 ) + ( 346 ) = 8831 J
8831J is the specific heat of the gas</span>
Maybe the first or third ☝️ one
I believe the correct answer from the choices listed above is option A. The reactant for the given chemical reaction would be NaHCO3 and HCl. <span>A </span>reactant<span> is a substance that changes in a chemical reaction. It is the starting material in a reaction. Hope this answers the question.</span>
Answer:
It's a rapid motion and collisions of molecules with the walls of the container that causes pressure.
