2H2 + O2 + 2H20

If you have 50 grams of hydrogen (H2), how many moles of water (H20) could be

produced?

Study the following two reactions. Select all that apply. C (graphite) + O2 (g) → CO2 (g) + 94.05 kcal C (diamond) + O2 (g) → CO2 (g) + 94.

Consider the reaction N2 (g) + 3H2 (g) → 2NH3 (g) Suppose that at a particular moment during the reaction, molecular hydrogen is reacting at the rate of - 0.091 M/s.

When you overshoot during titration what is the result

Arrange the complexes in order of decreasing stability. Rank from most stable to least stable. To rank items as equivalent, overlap them. [Ni (en) (H2O) 4] [FeF6] [Fe (NH3) 6] [Ni (en) 3])

If you drop a 200 gram piece of metal with a temperature of 110 degrees Celsius into 1000 grams of water at 25° Celsius, what best describes what would occur?

A chemical reaction can start when enough activation energy is added to the reactants. Do you think the activation energy for chemical reactions in living things is high or low / Explain your answer

20 Which statement describes a reversible reaction at equilibrium? (1) The activation energy of the forward reaction must equal the activation energy of the reverse reaction.

Count the total number of atoms in CaCO3: 2 3 4 5 6

Question #21TrueFalse The general name for a substance added to a reaction that affects the rate but is not consumed in the reaction is called a complex a. True b. False
