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. Reset Help 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.

Reset Help This ion forms ionic bonds with nonmetals. This ion has a 1- charge. This is a polyatomic ion. The neutral atom from which this ion is formed is a metal. The atom from which this ion is formed gains an electron to become an ion. The atom from which this ion is formed loses an electron to become an ion. This ion has a total of 18 electrons.

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
