Consider the decomposition of ammonium hydroxide into ammonium oxide and water. If 5.00 g ammonium hydroxide are present in a 2.00 L container with 1.12 x 10-1 mol ammonium oxide and 4.30 x 10-2 mol water at equilibrium, what is the equilibrium constant? Does this reaction favor the reactants or the products?

Naoki's bicycle has a mass of 10 kg. if naoki sits on her bicycle and starts pedaling with a force of 168 n, causing an acceleration of 2.8 m/s2, what is naoki's mass?

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
