Given the following equation: 2F2 + 2H20 + 4HF + O2 What mass of fluorine is needed to completely react with 3.6 grams of water? Molar mass of F2 = 38.00 g/mol Molar mass of H20 = 18.02 g/mol)

7.59 g

Explanation:

To solve this, you need to look at the stoichiometry of the equation.  For every 2 moles of H₂O, 2 moles of F₂ are needed to completely react.  This means that however many moles of H₂O you have, the same amount of moles are needed for F₂.

Convert grams of H₂O to moles using the molar mass.  moles = 0.1998

Since moles of H₂O are equal to moles of F₂, you have 0.1998 moles of F₂.  Now, convert this to grams using the molar mass.  grams = 7.59

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
