A mixture initially contains A, B, and C in the following concentrations: [A] = 0.600 M , [B] = 0.950 M , and [C] = 0.550 M . The following reaction occurs and equilibrium is established: A+2B⇌C

At equilibrium, [A] = 0.460 M and [C] = 0.690 M . Calculate the value of the equilibrium constant,

Aphysical reaction is a process in which one or more reactants change into one or more products with different properties. select the best answer from the choices provided t f

When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number a. electrons within the moleculeb. bonding and unshared pairs around central atomc. unshared pair within the molecule( i really need it )

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
