Answer #1
  1. ANSWER: A

EXPLANATION:

The basic concepts of chemistry like Quantum theory, Schrodinger wave equation, Quantum mechanical model of atom etc depends on both Classical mechanics and Quantum mechanics.

2) ANSWER: A

EXPLANATION:

The rate of a reaction depends on the concentration of reactants. In the reversible reaction ,if the time goes on the concentration of reactants decreases and concentration of products increase. Therefore the rate of a chemical reaction from its initial value until the forward reaction rate equals to the reverse reaction rate ie to attain the equilibrium.

    please help with all pre-lab Dynamic Equilibrium Simulation with Pennies 1 of 11 on Equilibrium is a state where there are no observable changes over time. Equilibrium is achieved when the rate of the forward reaction equals the rate of the reverse reaction. R =P In this activity, we will simulate a reversible reaction where R = P: the reactant molecules (R) are pennies, which react and are transferred from the side to the P side, while the product molecules...
