Hydrogen gas reacts rapidly with oxygen gas in the presence of a platinum catalyst. which equation correctly represents this reaction?

2H₂(g) + O₂(g) → 2H₂O(g), in presence of Pt as a catalyst.

Explanation:

The reaction:

2H₂(g) + O₂(g) → 2H₂O(g), in presence of Pt as a catalyst.

2.0 moles of hydrogen gas react with 1.0 mole of oxygen gas to produce 2.0 moles of water vapor in presence of Pt as a catalyst.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
