ii. Use the solubility table to label the state symbols of each compound in the reaction. (1 point) AgNO3 + KCL = AgCl + KNO3
rjkz [21]

Answer:

  • AgNO₃ (aq) + KCl (aq) → AgCl (s) + KNO₃ (aq)

Explanation:

In a <em>solubility table</em> you find:

  • AgNO₃ (silver nitrate) is highly soluble
  • KCl (potassium chloride) is soluble
  • AgCl (silver chloride) is insoluble
  • KNO₃ (potassium nitrate) is soluble

In a chemical equation the states of soluble compounds is identified as aqeous, using the letter "aq" in parenthesis, and the state of insoluble compounds is identified as solid, using "s" in parenthesis.

Then, the reaction showing the states of the reactants and products is:

  • AgNO₃ (aq) + KCl (aq) → AgCl (s) + KNO₃ (aq)

Which of the following is generally FALSE? Group of answer choices Elements in the same group have the same valence electron con
Whitepunk [10]

Answer: Option (c) is the correct answer.

Explanation:

Generally, when we move from top to bottom in a group then there occur increase in the number of electrons due to which there will also occur increase in the number of shells.

As atomic size is the distance between the nucleus and valence shell of an atom. Hence, more is the number of shells present in an atom more will be its atomic radius.

Thus, we can conclude that the statement atomic radius of elements in a group decreases as you go from top to bottom, is generally FALSE.
