Answer:
IUPAC name the compound with their number of each atom.
Explanation:
a) manganese dioxide: (Mn +4) ⇒ MnO2
b) mercurous chloride was canceled by the IUPAC, it is correct Mercury chloride. (Hg +1) ⇒ Hg2Cl2
c) Ferric nitrate: Iron (III) nitrate.
d) It is correct.
e) cupper dibromide
Delta Hf = dHf
<span>dHf rxn = (n*dHf products) - (n*dHf reactants). </span>
<span>Substitute 5113.3 kJ for dHf rxn and solve for the only unknown in the equation which is dHf C8H18.
</span>-5133.3-[(8x-393.5)+9(-241.8)] = 190.9
<span>Since it is an enthalpy of formation, the value has to be negative, </span>
<span>thus the correct answer is -190.9</span>
It's also called a continental<span> plate, convergent or divergent boundary, or c</span>ontinental<span> drift.</span>
Answer:
The temperature would be reduced by half
Explanation:
Charles' Law => V ∝ T => V = kT => k = V/T
For two sets of T vs V conditions, the system constant (k) remains unchanged and k₁ = k₂ => V₁/T₁ = V₂/T₂.
Therefore, if V₁ is reduced to 1/2V₁ = V₂ => V₁/T₁ = 1/2V₁/T₂ => V₁/T₁ = V₁/2T₂
and solving for T₂ => 1/T₁ = 1/2T₂ => 2T₂ = T₁ => T₂ = 1/2T₁
∴ The initial temperature (T₁) would be reduced by half or, T₂ = 1/2T₁
