Answer:
molar mass for the
compound aluminum carbonate, Al2(CO3)3
233.99 g/mol
Answer:
-2092 kJ
Explanation:
Let's consider the chemical reaction that causes chromium to corrode in air.
4 Cr + 3 O₂ → 2 Cr₂O₃
We can calculate the standard Gibbs free energy (ΔG°) using the following expression.
ΔG° = ΔH° - T × ΔS°
where,
- ΔH°: standard enthalpy of the reaction
- ΔS°: standard entropy of the reaction
ΔG° = -2256 kJ - 298 K × (-0.5491 kJ/K)
ΔG° = -2092 kJ
Answer:
gradient
Explanation:
Unlike the change in pressure and density, which decrease with altitude, changes in air temperature are not regular. A change in temperature with distance is called a temperature <em>gradient.</em>
The neutralization pH of an HCI solution with KOH solution is 7
The ionization reaction of the compound given are as follows:
1.) HI(aq)
HI(aq) -----> H+(aq) + I-(aq)
2.) LiOH(s)
LiOH(s) ------> Li+(aq) + OH-(aq)
Ionization<span> is the process by which an atom or a molecule acquires a negative or positive charge. Hope this helps. Have a nice day.</span>
