This should be most likely true
Answer:
has 6 valence electrons as its in group 6
the atom will gain electrons
the charge will be 2- as it will gain 2 electrons to be a full configuration
Since the mole ratio is 1 to 1 for this reaction, you can just use M1V1 = M2V2 to solve, given that 1 refers to HBr and 2 refers to LiOH.
M1 = ?
V1 = 0.40 L
M2 = 0.50 M
V2 = 0.20 L
M1(0.40) = (0.50)(0.20)
Solve for M1 —> M1 = (0.50)(0.20)/0.40 = 0.25 M HBr
Answer:
ΔG° = - RTLnK is used to find the standard cell potential given the equilibrium constant
Explanation:
for an ideal disolution:
⇒ ΔG = RT∑ni LnXi
∴ ΔG = ( μi - μi*)ni
∴ μ : chemical potential
∴ μ*: chem. potential of the pure component at T and P.
⇒ ΔG = μi - μi* = RT LnXi
for a equilibrium reaction:
⇒ ∑ νi*μi = 0
⇒ ΔGr = ΔG°+ RT Ln Kx = 0
⇒ ΔG° = - RT LnKx
Matter only moves if a force pushes or pulls is true
