If this is wrong im sorry, Im gonna go with 8.
Mass of Zn = 0.103 g
Volume of HCl (V) = 50.0 ml
Density of solution (D) = 1.00 g/ml
Mass of HCl = D*V = 1.00 g/ml * 50.0 ml = 50.0 g
initial temp T1 = 22.5 C
Final temp T2 = 23.7 C
specific heat c = 4.18 J/g C
The heat (Q) required to raise the temp is given as:
Q = mcΔT = mc(T2-T1)
= (0.103+50)g * 4.18 J/g C * (23.7-22.5) C = 251.3 J = 0.2513 kJ
To find ΔH in kJ/mol
# moles of Zn = mass of Zn/Atomic mass = 0.103/65.39 = 0.00158 moles
a) ΔH = 0.2513 kJ/0.00158 moles = 159.05 kJ/mol
b) A calorimeter is an isolated system where there is no exchange of heat/energy.
Work done is given as: W = PΔV
since ΔV = 0, as the volume remains constant
W = 0
I found this on google
“The periodic table is important because its is organized to provide a great deal of information about elements and how they relate to one another in one-easy-to-use reference. The table can be used to predict the properties of elements, even those that have not been discovered.”
I hope this helps
Molecular simulation is the part of the drug discovery life cycle that most likely uses quantum computing.
<h3>What is drug discovery?</h3>
Drug discovery refers to the process to identify and validate medications in pharmaceutical research.
Drug discovery exploits computational approaches based on quantum modeling to accelerate this process.
In conclusion, molecular simulation is the part of drug discovery associated with quantum computing.
