Question

someone who’s good with science this is for you btw I’ll brainlist and rate 5 star due today.



Write the word equation for each of the following metal oxidation reactions also the chemical equations below it.


1) Osmium reacts with oxygen in the air to form a highly toxic chemical called osmium oxide
​​​​+​​​=
​​​​+​​​=

Answer 1

Answer:

Solid Osmium transition metal reacts with Oxygen gas to produce solid Osmium tetroxide.

Os(s) + 2O₂(g) -> OsO₄(s)

Explanation:

Osmium tetroxide is another way of writing Osmium (VIII) oxide.

Leaving powdered osmium exposed to air in a room will slowly create osmium tetroxide at room temperature.

Similarly, osmium tetroxide vapor will readily be released from a liquid solution at room temperature.
