How many moles of CO2 are produced when 80.0 grams of O2 are used
C3H8 + 5O2 = 3CO2 + 4H2O

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

Which of the following are good traits of a hypothesis? it will be able to be testedit can predict an outcomeit will explain the observationsall of these
