The fact that hbo2, a reactive compound, was produced rather than the relatively inert b2o3 was a factor in the discontinuation of the investigation of the diborane as a fuel. what mass of liquid oxygen (lox) would be needed to burn 296.1 g of b2h6?

1027.62 g

Explanation:

For  :-

Mass of  = 296.1 g

Molar mass of  = 27.66 g/mol

The formula for the calculation of moles is shown below:

Thus,

From the balanced reaction:-

1 mole of react with 3 moles of oxygen

Thus,

10.705 mole of react with 3*10.705 moles of oxygen

Moles of oxygen = 32.115 moles

Molar mass of oxygen gas = 31.998 g/mol

Mass = Moles * Molar mass = 32.115 * 31.998 g = 1027.62 g

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
