Use the standard reduction potentials to calculate the standard free-energy change ΔG, and the equilibrium constant, K, at 298 K for the reaction. 4Ag(s) + O2(g) + 4 H^+ (aq) → 4Ag+(aq) + 2H2O(l)

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
