BRAINLIEST!!HELP PLEAS2. Use the following chemical equation to answer the question. 4K(s) + O2(g) → 2 K20 (s)
If a staff member at a laboratory has 12.0 grams of potassium metal, what is the
theoretical yield of potassium oxide (K2O) that the scientist could potentially
produce from the reaction with oxygen gas?

The equation of the chemical reaction between potassium (K) and oxygen (O2) is: 4K + O2 --> 2K2O

From the equation it is seen that 4 moles of potassium react with with one mole of oxygen gas (O2) to give 2 moles of potassium oxide.

The molar mass of...

Explanation:

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
