Assuming all volume measurements are made at the same temperature and pressure, how many liters of oxygen gas would it take to react completely with 7.25 liters of hydrogen gas? show all of the steps taken to solve this problem. (4 points) balanced equation: 2h2 (g) + o2 (g) yields 2h2 o(g)

If the same amount of cacl2 is added to equal volumes of water and maple syrup, which will have the higher temperature?

Si una estrella no tiene paralaje medible, ¿qué puedes inferir?

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
