If a sample of N2O4 contains 5.55 x 10^22 nitrogen atoms, what is the mass of the sample (in g)?

Express the following number in scientific notation. 0.026890 =

The climate of the continental united states is generally 1. tropical 2. temperate 3. arctic 4. highland

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
