Selina claims that combining copper sulfate and zinc created a chemical reaction. Identify the evidence of chemical or physical changes in the experiment. Explain why Selina is correct or incorrect using evidence from the experiment. Describe what happened to the copper sulfate and zinc atoms during the experiment. Explain your answer.

where are the choice options?

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
