Answer:
pV=nRT; p=nRT/V
p=0.552Mol*8.314J/MolᵒK*305K/0.0085m³=164675.887Pa
p=1.625atm
1.625atm*14.7psi/1atm=23.888psi
Naproxen is known to be a weak acid. In order to calculate
its ka and pka, use the equation of getting the ph of weak acid which is ph=
-1/2 log [(Ka)(Mwa)]. The Ka value is 3.18x10^-5. The pKa can be obtained
through pKa = - log Ka. The pKa is 4.5.
Because we don't know the final state, let's test if it goes through melting stage.
Q = mΔHfus, where ΔHfus for water is 333 kJ/kg
Q = 333 kJ/kg(0.1 kg) = 33.3 kJ
So, it means the final state is liquid water. The remaining Q would now be: 35.1 - 33.3:
Q = mCp,iceΔT + mCp,waterΔT
Q = (0.1 kg)(2.108 kJ/kg°C)(0 - -4.5) + 0.1 kg(4.187 kJ/kg°C)(T - 0) = 35.1 - 33.3
Solving for T,
<em>T = 2.03°C</em>
Based on the chemical equation, to balance the equation we use 2 as a coefficients of HCl on left hand side of reaction.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.
Given chemical reaction is:
Zn + HCl → ZnCl₂ + H₂
Above reaction is not balanced equation as number of chlorine and hydrogen atoms are not same, so balanced equation will be:
Zn + 2HCl → ZnCl₂ + H₂
Hence we add 2 as a coefficient of HCl to balance the equation.
