If the LEL for hydrogen = 4% and the UEL = 74% what mass of hydrogen was contained in the 500mL tin when it exploded?

(conditions at the time of the experiment were 23oC and 750 mmHg)

Unsure how to go about this question...please show working out for me :)

the freezing point of a solution containing 0.2 gram of actic acid in 20 gram of benzene is lowered by o,45 celsuis. calculate molar mass of actic acid and van hoff factor.

Tell about the difference of inner and outer transition elements in detail.

A flask in a sealed room that is devoid of oxygen contains 16.05 g of magnesium silicide. An acid HA, where A is a halogen, is added, and a double-replacement reaction occurs. One of the products is a solid, but the other is a gas that escapes from the flask. The mass of the contents of the flask is measured to be 39.85 g. Assuming that the reaction went to completion (that is, neither reactant occurred in excess),
(a) determine the name of the acid.
(b) mathematically prove which product was the gas.

How much energy (in kilojoules) is needed to heat 5.40g of ice from -10.5∘C to 35.0∘C? The heat of fusion of water is 6.01kJ/mol, and the molar heat capacity is 36.6 J/(K⋅mol) for ice and 75.3 J/(K⋅mol) for liquid water.
