Mols CuSO4 = M x L = 1.50 x 0.150 = 0.225
<span>mols KOH = 3.00 x 0.150 = 0.450 </span>
<span>specific heat solns = specific heat H2O = 4.18 J/K*C </span>
<span>CuSO4 + 2KOH = Cu(OH)2 + 2H2O </span>
<span>q = mass solutions x specific heat solns x (Tfinal-Tinitial) + Ccal*deltat T </span>
<span>q = 300g x 4.18 x (31.3-25.2) + 24.2*(31.3-25.2) </span>
<span>dHrxn in J/mol= q/0.225 mol CuSO4 </span>
<span>Then convert to kJ/mol

Explanation:
Hello there!
In this case, since this imaginary gas can be modelled as an ideal gas, we can write:
Which can be written in terms of density and molar mass as shown below:
Thus, by computing the pressure in atmospheres, the resulting density would be:
Best regards!
You have to solve it and color in the numbers i guess? It doesnt show all of the work
If the mass of both the reactants is 10kg then the mass of the products also equals 10kg.
It is due to the law of conservation of mass.
Mass can neither be created nor be destroyed.
Answer:
Nature involves the charecterists we inherit through our genes, hence why we often hear the phrases “You’re just like you’re mother/father” from friends or other family members. Whereas, nurture includes the influence of the environment or our surroundings within childhood, on our later personalities and behaviour.
