The enthalpy change associated with the precipitation reaction is 84 kJ/mole
Why?
The chemical equation for the reaction can be written as
AgNO₃(aq) + NaCl (aq) → AgCl(s) + NaNO₃(aq)
To determine the enthalpy change, the following equation applies

To calculate the heat (Q):

Next, we need to calculate the number of moles involved in the reaction (n):
![n=[AgNO_3]*v(L)=(0.1M)*(0.05L)=0.005moles](https://tex.z-dn.net/?f=n%3D%5BAgNO_3%5D%2Av%28L%29%3D%280.1M%29%2A%280.05L%29%3D0.005moles)
With these two values, we can substitute them into the first equation:

Have a great day!
The mass calculated for the copper piece is 290 grams. The formula for mass is given by mass = density × volume, where the density of copper is 8.96 grams per mL. The volume of the copper piece, determined by the increase in volume, equals 137 mL - 105 mL = 32 mL. Multiplying the volume by the density gives us the mass of copper: mass = 8.96 g/mL × 32 mL = 286.72 grams. Since the volume is presented with two significant figures, rounding the mass to two significant figures results in 290 grams.
The production mechanism for t-butyl alcohol proceeds as follows:
The reaction and corresponding rate law for isobutene adsorption on the Amberlyst-15 catalyst can be described by:
I + S ⇄ I * S 
where
represents the concentration of unoccupied sites
denotes the adsorption equilibrium constant
indicates the forward rate constant
are the concentrations of isobutene and the site occupied by isobutene
The equation for the adsorption of water (W) onto the Amberlyst-15 catalyst is outlined as:
W + S ⇄ W.S 
The surface reaction's rate law can be described as:
W.S + I.S ⇄ TBA. S + Sn 
The desorption rate law for TBA from the catalyst is as follows:
TBA. S ⇄ TBA + S
