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)

Describe at least two experiments, including the observed results, that caused the scientific community to accept changes to Dal
WINSTONCH [101]
The model after John Dalton's was J.J Thompson's plum podding model in 1897, which described electrons as dots or raisins(if you will) in a circle shaped pudding that was entirely positive using a Cathode Ray Tube(shot cathode rays between magnets). The model after that is the Niels Bohr model in 1913, which depicts atoms like positively charged center called the nucleus with negatively charged particles called electrons in a shell or cloud.

Which of the following correctly represents the transmutation in which a curium-242 nucleus is bombarded with an alpha particle
Alekssandra [29.7K]

<u>Answer:</u> The chemical equation is written below.

<u>Explanation:</u>

Transmutation is defined as the process in which one chemical isotope gets converted to another chemical isotope. The number of protons or neutrons in the isotope gets changed.

The chemical equation for the reaction of curium-242 nucleus with alpha particle (helium nucleus) follows:

_{96}^{242}\textrm{Cm}+_4^2\textrm{He}\rightarrow _{98}^{245}\textrm{Cf}+_0^1\textrm{n}

The product formed in the nuclear reaction are californium-245 nucleus and a neutron particle.
