avagrados law relates the volume of gas to the number of moles of gas when temperature and pressure are constant. according to this law, how would the volume of gas change if a reaction produced 3 moles of gas from 1 mole of gaseous reactions

Identify the electromagnets with poles that are reversed from the electromagnet shown above

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

If a gas has an initial pressure of 101kpa and a volume of 10l, then it expands to a volume of 20l, what is the new pressure?
