The starship enterprise uses the compound, B5H9 and oxygen gas as fuel. This is the balanced equation: 2B5H9 + 12O2 = 5B2O3 + 9H2O
If one fuel tank holds 126 g of B5H9 and the other holds 192 g of Oxygen how much B2O3 will be produced? What is the limiting reagent? How much of the excess fuel will be left over? If 171.3 g of B2)3 is actually produced, what is the percent yield?

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

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?
