Answer: -2.4 kJ/mol
Explanation:
We can relate
to
according to:
![\Delta G=\Delta G\°+RTln(\frac{[products]^n}{[reagents]^m})](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5CDelta%20G%5C%C2%B0%2BRTln%28%5Cfrac%7B%5Bproducts%5D%5En%7D%7B%5Breagents%5D%5Em%7D%29)
Where [products] is the concentration of products, [reagents] is the concentrarion of reagents, n and m are the corresponding stoichiometric coefficients, T is the temperature in Kelvin and R is the gas constant.
Converting 37°C to Kelvin by adding 273, mM to M dividing by 1000, and substituting we get:

That gives us a value of -2.4 kJ/mol, the fouth option.
Answer:
Choices 2 and 4
Explanation:
HCL is formed witthe the elements Hydrogen and Chlorine. Whatever is on the left side of the equation must match up with the right side of the equation.
2. H + Cl --> HCl (we have one hydrogen and one chlorine)
4. 2HCl --> H2 + Cl2 (since the two is distributed to both the H and the Cl, H has 2 and Cl has two on the left side AND on the right side of the equation)
Answer:
a) 2NaOH+H2SO4→Na2SO4+2H2O2NaOH+H2SO4→Na2SO4+2H2O
b) Số phân tử NaOH : Số phân tử H2SO4 = 2:1
Số phân tử NaOH : Số phân tử Na2SO4 = 2:1
Số phân tử NaOH : Số phân tử H2O = 2:2
