Drag the appropriate items to their respective bins.
View Available Hint(s)
The forward and reverse reactions
proceed at the same rate.
Chemical equilibrium is a dynamic
state.
The ratio of products to reactants is
not stable.

The state of chemical equilibrium will
remain the same unless reactants or
products escape or are introduced into
the system. This will disturb the
equilibrium.
The concentration of products is
increasing, and the concentration of
reactants is decreasing.
The ratio of products to reactants
does not change.
The rate at which products form from
reactants is equal to the rate at which
reactants form from products.
The concentrations of reactants and
products are stable and cease to
change.
The reaction has reached equilibrium.
The rate of the forward reaction is
greater than the rate of the reverse
reaction.

Units Valuearrow_forwardLearning Goal: This question reviews the format for writing an element's written symbol. Recall that written symbols have a particular format. Written symbols use a form like this: 35 Cl 17 In this form the mass number, 35, is a stacked superscript. The atomic number, 17, is a stacked subscript. "CI" is the chemical symbol for the element chlorine. A general way to show this form is: It is also correct to write symbols by leaving off the atomic number, as in the following form: atomic number mass number Symbol 35 Cl or mass number Symbol This is because if you write the element symbol, such as Cl, you know the atomic number is 17 from that symbol. Remember that the atomic number, or number of protons in the nucleus, is what defines the element. Thus, if 17 protons are in the nucleus, the element can only be chlorine. Sometimes you will only see 35 C1, where the atomic number is not written. Watch this video to review the format for written symbols. In the following table each column…arrow_forward
