Giving brainliest ✅✅ 5. Which reaction is an example of heterogeneous catalysis? (1 point)

A Ethene gas reacts with hydrogen gas by using a nickel catalyst.

B Hydrogen peroxide decomposes by using an aqueous iodide ion catalyst.

C Formic acid decomposes by using an acidic catalyst.

D Sulfur dioxide gas is converted to sulfur trioxide gas by using nitrogen chloride gas.

A

Explanation:

A common example of heterogeneous catalysis is the hydrogenation reaction of simple alkenes. The conversion of ethene (C2H4) to ethane (C2H6) can be performed with hydrogen gas in the presence of a metal catalyst such as palladium (“Conversion of Ethene to Ethane with Hydrogen and a Metal Catalyst”).

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
