Hydrogen is collected by downward displacement of water as it is less denser than water. Hence it comes out at the surface of water . It is insoluble in water so it does not dissolve in water
Hydrogen gas is almost insoluble in water,it can be collected by displacement of water using an inverted apparatus. Hydrogen is highly explosive when mixed with air. Hydrogen is explosive when mixed with air so burns with explosion near the mouth of gas jar but burns out inside the jar because the burning requires the presence of oxygen which in not present inside the jar
diatomic hydrogen is written as H2 (2.02 grams H2) <------- if each hydrogen atom is 1.01 grams, then two hydrogen atoms are 2.02 grams 2.0 moles H2 X 2.02 grams H2 ------------- (divide to cancel moles) = 4.04 grams/mole H2 ÷ one mole = 4.04 grams H2
The answer to this question would be: <span>85c </span>Solubility is influenced by the temperature of the molecule. Higher temperature will result in a higher solubility. That is why brewing using hot water will be easier than using cold water. Higher temperature also means higher reaction rate.
