Halogens (atoms with 7 valence electrons) and Hydrogen
or generally, atoms with their shells almost full
A .compound is the combination of two or more atoms
Answer:
A nonspontaneous process
Explanation:
The spontaneity of a reaction is given by the standard Gibbs free energy (ΔG°). We can calculate ΔG° using the following expression.
ΔG° = ∑np . ΔG°f(p) - ∑nr . ΔG°f(r)
where,
ni are the moles of reactants and products
ΔG°f(p) are the standard Gibbs free energies of formation of reactants and products
For the equation,
CO₂(g) → CO₂(aq)
ΔG° = 1 mol × ΔG°f(CO₂(aq)) - 1 mol × ΔG°f(CO₂(g))
ΔG° = 1 mol × (-386.0 kJ/mol) - 1 mol × (-394.4 kJ/mol)
ΔG° = 8.4 kJ
By convention, ΔG° > 0 means that the reaction is nonspontaneous.
14: All you need to do is find the 1/8 mark on the bone at 0 years. Find the bar that looks like it is equal to that 1/8 mark. It’s the bar right before 20. From the choices, the best estimate is d. 17,100.
15: The dependent variable is the amount of dissolved gases. This is because the amount of dissolved gasses is <em>dependent </em>on the air pressure (which would be the independent variable).
