How many moles of O2 could be obtained from one mole of KClO3 with the equation 2KClO3–> 2KCl+3O2

8.98 dm3 of hydrogen gas is collected at 38.8 °c. find the volume the gas will occupy at -39.9 °c if the pressure remains constant.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.

Ineed this awnser fast select the correct answer. this chemical equation represents the burning of methane, but the equation is incomplete. what is the missing coefficient in both the reactants and the products? ch4 + → co2 + a. 0 b. 1c. 2d. 3 e. 4
