Ozone depleting chemicals are most likely belong to <u>halogen </u>group on the periodic table.
<h3>Ozone depleting chemicals are most likely to belong to which group on the periodic table?</h3>
Ozone depleting chemicals are the halogen group on the periodic table. Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromo-fluorocarbons and methyl chloroform. Fluorine, chlorine, bromine, iodine, astatine and tennessine are the elements of halogen group elements. These elements greatly affected the ozone layer.
So we can conclude that Ozone depleting chemicals are most likely belong to halogen group on the periodic table.

Answer:
0.250L of solution. 0.250 moles of solute.
Explanation:
As you can see in the image, there is a beaker with an amount of solution. 1/2L are 500mL and each line of the beaker represents 100mL. That means the volume of the solution is approximately 250mL = 0.250L
Molarity is an unit of concentration defined as the moles of solute per liter of solution. A solution that is 1.000M contains 1.000 moles of solute per liter of solution.
As the volume of the solution is 0.250L, the moles are:
0.250L * (1.000mol/L) = 0.250 moles of solute
Answer:
Heat
Explanation:
Temperature is the average thermal energy (or heat) in a substance. Sound isn't really related, thermometers measure temperature, and chemical reactions can produce heat, but none of those are measured by temperature.
Answer:
The rate decreases as the concentration of the reactants decreases.
Explanation:
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
During a reaction, the concentration of a reactant decreases exponentially with time while that of a product increases exponentially with time. This is because a reactant is consumed in a reaction while products builds in that same reaction.
The reaction rate therefore is directly proportional to the concentration of the reactants.
